Update: It turns out, that the voltage regulator of a cheap Arduino Pro Mini clone I tried out is not capable to source the power needed for the RFM69HW, so please checkout the regulator on your Pro Mini before you try out this board!
I'm currently using a few ITEAD Nano io shield in my NRF24 network. There is a stronger voltage regulator on board, which allows to connect NRF24L01+PA+LNA version. I don't have to fumble with dupont wires to connect the radio and so on.
As I'm currently switching to RFM69 due to the lack of range with NRF24 in my house I searched for a similar board for RFM69 and found none. I decided to give kicad a try and here is my first board.
I've designed the board with this in mind:
I'm using straight headers (female) for FTDI on the Arduino Pro Mini.
As this is my first design I've ordered and already received a batch of these boards. The boards are working fine, but I've made a mistake connecting the barrel jack (I've switched VCC & GND). ;-) The mistake is fixed in the release here.
