Nano Memory Slot
It is called Nano Memory Card, and it is designed to fit a nano SIM card slot. The newly announced Mate 20 and Mate 20 Pro phones will only accept this NM card. According to the phone-maker, the NM. AMD has paired 4 GB HBM memory with the Radeon R9 Nano, which are connected using a 4096-bit memory interface. The GPU is operating at a frequency of 1000 MHz, memory is running at 500 MHz (1000 Mbps effective). Being a dual-slot card, the AMD Radeon R9 Nano draws power from 1x 8-pin power connector, with power draw rated at 175 W maximum. How to use a nano SIM in any phone The mechanics of using a nano SIM in a non-nano phone are simple enough. First choose the appropriate adapter – in this case the nano to micro one – pop in your SIM card and then pop the SIM/adapter combo in the card slot. Nano SIM cards will be the best bet for most newer phones.
From a hardware perspective the NANO SD is simply a NANO with a microSD card inserted. The microSD card slot is hidden between the two PCBs and fully operational on all NANOs out there. That means every NANO can be upgraded to a NANO SD. As a result the NANO SD is mainly operated like a NANO, it can do all a NANO can plus some extra. There is not much difference when you look onto the base operations. This data sheet summarizes the main specs.
What makes the NANO SD a better NANO?
To say it in one sentence, it adds some of the core Meteobridge PRO functions to the NANO. And on top of this it adds an exclusive feature, a Dashboard base on the HomweWeatherStation template from weather34.com. Please allow us to highlight a few aspects that might be of particular interest to you.
Local Storage of Data
The fundamental difference compared to a regular NANO is that the NANO SD has 2 GB of permanent storage while the NANO just has 16 MB onboard flash mostly covered by the operating system and the application programs. Equipped with 2 GB the NANO SD can hold about 20 years of data. NANO SD holds data for last 72 hours in a per minute resolution and older data in a per hour resolution. Hourly data can be inspected and edited through the NANO web interface. So it just needs a few clicks to select a sensor and the year, month and day to inspect. Data can be changed by simply clicking onto the corresponding value in the table at the bottom. When you change a value on per hour level, the changes will also be propagated to affected data of the day, month and year automatically. This makes handling of logged data rather intuitive and you don't need separate tools for it.NANO SD also allows to export data of user-defined time frames in various time resolutions. Specification of year, month, day is done in the upper part first. Then you can select a template that defines the structure of the export in the middle part. By pressing one of the export buttons a CSV data export is generated in the export folder of the microSD card. To transfer this data to your PC for follow-up processing or archiving you don't have to move the microSD card, but simply mount the NANO SD as a PC network share. This works natively on PC, Mac or Linux clients. That way the data store of the NANO can be used by all computers in your home network.
Generating Graphs
The NANO SD can generate powerful interactive charts based on the data stored locally. All you need to do is to select a chart type and time period to inspect and a time resolution. Having done so it just takes a few seconds for the chart to show up. When you move the cursor into the chart area a vertical ruler provides information about the point in time selected and data boxes for all sensors will show numerical data. Furthermore, you can customize the charts by clicking onto the sensors. This will activate or deactivate display of the touched sensor. The handles at time line's start and end can be moved to zoom in to areas that need further inspection.These charts are not restricted to be shown in the NANO's web interface only. They can be requested as html responses from within your network or from the Internet (when remote access is enabled) by calling one of the specified link URLs. You can also store a self-contained copy of the chart to the chart folder of your microSD card by pressing the 'Export to charts folder' button and from there it is shared as a piece of javascripted HTML in your network. We have exported the shown chart HTML to our web server and you can inspect it with all its interactive features at this link: exported chart
Templates
Data export and chart generation are based on templates stored in the template folder of your NANO SD. Therefore, the output format is not hard coded but can be adapted to your needs. This will of course need you to define new templates, but by starting with copies of the pre-defined ones you can tap into this step by step. This also means that other people more familiar with this topic can design templates for you that exactly meet your demands. This level of versatility on data exports and chart generation in particular is rather unique in the world of consumer weather data processing. Graphs are build with the amcharts toolkit which is one of the market leaders in javascript charts and has a detailed documentation in the web which helps you to understand how to adapt charts to your needs.
Uploading Data Exports and Graphs
Having graphs or data exports on the NANO SD in your home network is fine, but many users would like to have periodically generated charts uploaded to their web servers. This allows for making the data public without giving other user access to a device in your home network. Therefore, NANO SD can periodically generate data and charts and can upload it to the Internet. This can be done via FTP or SFTP. Setting up these features just needs a few clicks. You can freely select the interval of data generation and upload and whether the file should be deleted from the NANO's local storage when upload is done. Folder and filename to be used for storage on the web server can be specified in a way that allows to include date information. This is useful to build up an archive of daily chart over time, for example. The example on the right generates every hour a graph of todays weather data, then uploads it, gives it a name containing year, month and day and finally removes it from the NANO SD storage to avoid filling up local storage.
Beside uploading to a web server you also can generate data exports or charts and send them by email with the data or graph as an attachment.
HomeWeatherStation Dashboard
The tiny shape of the NANO SD should not trick you regarding its power. We managed to port the famous HomeWeatherStation template including the needed PHP stack onto the NANO SD and as a result the current and historical data can be accessed in a beautiful and convenient way. You don't have to install anything, just a few clicks on 'Weather Network' tab are needed. The dashboard even allows to show forecast and current conditions data. To have that added you simply add individual API keys DarkSky and WXcheck are providing for free for private use. Having the remote login feature of Meteobridge enabled, you can even inspect the Dashboard from the Internet and you can share the link with friends as it does not need the Meteobridge password that protects the admin web interface. To cite a user: 'A Davis Envoy + NANO SD + Tablet = Awesomeness!'
As you see there is quite a lot a NANO SD can do more than a pure NANO.

Choice of microSD Card
To avoid lots of system fails caused by worn out consumer microSD cards we restrict microSD cards that can be used in the NANO to 1GB and 2GB industrial SLC cards. These are world-wide available from Mouser and other electronic distributors. We decided to enforce use of these high endurance cards to avoid having tons of unnecessary support requests and not to harm the reputation of the NANO SD by failed cards. Please trust in our experience with flash storage issues that there is simply no reasonable way to avoid buying of high-price, high-endurance SLC storage. These are the currently supported microSD cards:

Nowadays, the smartphone market is filled with different type of smartphones. You will find variation in the processor, RAM, storage space, camera, technology and various other features. Some phones are better than others in one thing or other. So, even we can’t know which phone we are going to buy after 3 months. However, the overall technology is improving. It’s moving forward. And, in the forward direction, we can be sure about at least these things that fast variants of the current phone will be coming, new phones with more RAM, slim design will appear.
Looking at the statistics, we can be sure about one more important thing – Nano SIM cards are the future. Mini SIM cards (2FF) have already become obsolete as this SIM card size is only being used by old or very low budget phone. Read the rumors, facts & reviews about upcoming smartphones on TechieWord. New smartphones which are coming to the market or the good smartphones who are ruling the market from past few years (in every price category) support either Micro SIM cards or Nano SIM Card. And, if you seek for popular smartphone, most of them support only Nano-SIM card.
So, if you’re going to buy a new SIM card from any telecom operator, choose their combi SIM card which comes with Mini SIM & Micro SIM cards support or trio SIM which supports all three type of SIM cards Mini SIM (2FF), Micro SIM (3FF) and Nano SIM (4FF) all in one SIM. If you own a trio SIM you can use it as a Nano SIM or club together the pieces to create Micro SIM or Mini SIM out of it.
However, if you are not looking for buying new SIM card but use your current number (SIM Card) to your new smartphone instead which supports only Nano SIM card then the only option left is to cut Mini or Micro SIM card to Nano SIM Card Size. You need to cut your SIM card very carefully to Nano SIM card size because if any mistake happens and you end up cutting SIM card circuits, it will be dead and you won’t be able to use it anymore on any device. But, no worries we are here to guide you step-by-step on how to cut your Mini or Micro SIM to Nano SIM.
Before following this article to know how to cut your SIM card to Nano SIM Card, remember once you’ve cut the SIM card there’s no going back. After cutting your SIM Card to Nano-SIM card size, you can’t use it in any other phones having Micro or Mini SIM card slot.

How to Convert Mini/Micro SIM to Nano SIM
While cutting your Regular or Micro SIM Card to Nano SIM card, the size of your SIM card should be accurate to Millimeters (not more and not less) to make it work properly as Nano SIM card. So, it’s risky to cut the SIM Card by just measuring dimensions. To cut your SIM card safely to Nano SIM card, follow these steps to ensure success:
Step 1: Get the SIM Card Cutting Template
The best way to cut SIM card is to do it using SIM cutting template because there is no UNDO in real life. If you make any mistake, there is no going back. So, you need to cut SIM card to the exact Nano SIM Card size and for that, use the standard SIM card cutting template.
Download SIM Card Cutting Template from here which contains template to cut MiniSIM to MicroSIM, MicroSIM to NanoSIM and MicroSIM to NanoSIM. Print this SIM Card Template at 100% scale on a DIN A4 sheet and you will have the perfect SIM Card cutting template with exact sizes to trace for your SIM Card.
Step 2: Trace Cut Lines to your SIM Card
Once you have printed out the template, choose whether you want to cut MiniSIM to MicroSIM, MicroSIM to NanoSIM or MicroSIM to NanoSIM and on the desired section, put your SIM card over the cut lines sketch. Now, trace the cut lines over your SIM card which have been hidden by SIM card.
Use a permanent marker to trace cut lines over your SIM card and to ensure precision, you can even tape the SIM card above sketch (like above image).
Step 3: Cut The SIM Card
Now, the most careful step comes when you need to cut the SIM card. Once you’ve traced cut lines, pick SIM card from the SIM Card template. Now, take a sharp knife and cut your SIM card to appropriate size slowly.
Once done, insert your newly created Nano SIM card to the Nano SIM card slot and check it. Your SIM card should be working correctly.

Nano Memory Slot App
Using the above method, you will be able to cut your Regular (Mini) or Micro SIM card to Nano SIM card size perfectly but by this method, you won’t be able to use the Nano SIM to Micro SIM or Regular SIM. However, if you use trio or even SIM card cutters (available on Amazon) it can cut your SIM card to the desired size in such a way that you can club the pieces together to form Micro or Regular SIM card out of it again.
