Meteobridge NANO SD
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
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.
Uploading Data Exports and Graphs
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.
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:
- swissbit SFSD1024N1BM1TO-I-DF-2A1-STD (microSD Card, 1 GB, SLC Flash, -40°C - 85°C)

How to insert a microSD Card into the NANO?
Inserting the microSD card between the two PCBs can be easily done with the help of a simple to build one-time paper tool. Please read details here or watch the video below.
NANO SD tutorial videos
To give you an impression how easy NANO SD features can be used, we compiled a few tutorial videos. Don't expect youtube entertainment. It is more a commented click stream but we think that explains best how it works and how to realise use cases that might be relevant to you.
NANO SD new functions
This video shows the most prominent additional functions the NANO gets by adding a microSD card. Operation of the two new tabs "History" and "Graphs" is explained and demoed.
Generating and Uploading
This video shows how data exports and chart generation can be put on a time schedule and how to automatically upload results to your web server via FTP.
