I really like this design and looking forward to the final working product. I am interested in this for a project where I need to place multiple temp/humidity sensors in multiple containers and I am looking to design and 3D print a small case that would hold an 18650 battery, Arduino pro mini, RFM69, and temp sensor.

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
