Embedded Mesh Rider Radio Evaluation Kit

The Embedded Mesh Rider Radio Evaluation Kit uses the same PCB as the External Radio with the following important changes.

1. In Fig. 1, (i) the reset button is not connected to the Mesh Rider Radio. Use the pin-hole reset on the Mesh Rider Radio instead.
2. In the AUX1 Connector (d), pins 1 and 2 use 0V - +3.3V TTL signalling levels instead of RS232.
