@tiana I have not used it, but it is possible to create different revisions. See https://www.openhardware.io/view/4/EasyNewbie-PCB-for-MySensors#tabs-revisions as an example.

Here the picture of the assembled board. The top board is a temperature sensor so not necessarily needed.

Please provide the required documentation for the CERN license. See here if anything is unclear.

@Alan-Minor said in Small nRF24L01+ Shield for ESP8266 Wemos D1 Mini: @NeverDie "Move" the trace to a different pin. AFAIK, yes.

There are also other solutions that have I2C bus pins on the shield and if you are going to make a battery powered node, I'd suggest to use an I2C sensor as it will be much more battery friendly
