A mini shield for an Arduino Mini Pro to simplify the connection to the RFM69W or RFM69HW "below" the Arduino (see the pictures for clarification).
It includes space for a 1206 capacitor to stabilize the supply voltage, (tested with 10uF) and includes all the necessary connections for the radio.
Also included is pcb pad to connect horizontally a PCB SMA plug, or a wire antenna.
