Here's a similar, related project for an Arduino Pro Mini: https://www.openhardware.io/view/480/Compact-nRF24L01-Pro-Mini-Bottom-Shield

I also have project for mini.
The project have pads for battery, battery protection IC, LIPO charger USB for charging... battery voltage measurements....
But the project is not released yet, because high temperature during charging.

Here is the code works with devDuino v2.2 It shows how all of the sensors on board (via com port) and also makes it possible to (expect) to download the firmware over the air. (for example through MYSController) /* This sketch is for a devDuino SN v2.2 with the support OTA http://www.seeedstudio.com/wiki/DevDuino_Sensor_Node_V2.2_(ATmega_328) and MySensors 1.5 For testing all the equipment, press the button D4 when a voltage is applied.

@NeverDie said in LCDUINO: the LCD components don't appear to be named, not even on the schematic Looks like a typical text LCD like 1602 on the picture.

Thank you @mfalkvidd! I have been busy and had many issues to figure out for myself, but I still can't understand how binding with openHAB works. How does the information from nRF24 get to openHAB? I have MySensors Binding add-on installed in openHAB. I would be very grateful if someone could help with this last step. After this my first little sensor will be ready to go live.

@NeverDie Sorry for delay... This is example (improved version with 3d printed fixer)
