Xbee Shield description:
Xbee Shield specification:
Xbee Shield pinout:
Unlike most shields this one has the headers reversed: it has female headers on the shield, and expects male headers to be fitted to the Arduino. This shield therefore can’t be used with a normal Arduino that has female headers.
Uses TX/RX pins for Zigbee connectivity.
The Maker claims it also uses pins D3-D7, but I can’t find any explanation of why and there are no design files published. I’ve left them marked as used until I get clarification.
