+ | ===== Modification of RFM12 power pin (PCB < V1.1) ===== | ||
+ | |||
+ | In PCBs >= V1.1, the RFM12 power pin is connected to an ATMega I/O pin to make it possible to restart the transceiver if communication fails. | ||
+ | |||
+ | If you want to modify your old PCB version to have this feature as well, cut two traces carefully (marked red in the picture) and connect two pins of the RFM transceiver to the ATMega (marked green in the picture). | ||
