Reverse engineering the secrets of an RA-02 LoRa module

The electronupdate blog does a teardown of the RA-02 LoRa module.

Removing the RF shield shows a circuit board with 3 semiconductors:

1. The SX1278 Lora module
2. An RF switch
3. A NPN Transistor

Removing the SX1278 from its package shows the die photo (above).
