#224

Keeping promises is very important. So let’s check if the suppliers of our newer LoRa boards keep their promises. The first ESP32 boards were disappointing as I showed in video #182.
In today’s contest are:
- TTGO LoRa32 board Version 2.0
- TTGO LoRa32 board Version 2.1
- TTGO LoRa32 T-beam board
- LoRa32u4 II
I will measure the maximal output power and assume, that the receiving channel behaves similarly to the transmitting circuit. Not really true, but good for an approximation.
