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.

Hi @GertSanders, Do you happen to still have the Eagle project files from version 3 you created and shared on OSH Park? I'd like to add a set of pads for the mini smd version of the NRF24L01. If not, I'll just use the version 2 files from openhardware.io and try my best to recreate the changes you made between them. Kind regards, AH

@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.

@TommySharp Hmm dont really remember, but I think this was the solution https://github.com/knolleary/pubsubclient/issues/46

@cadet I'm no expert but I would have looked at the data sheet and measured up to make sure that the hardware are not defective in any way. http://ww1.microchip.com/downloads/en/DeviceDoc/39662c.pdf Or the radio. //Mattias

It depends if you want to use an antenna with some gain or not
Do we have any option to bridge NRF24L01 and RFM69?

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.
