RF wattmeter and Band Decoder on Arduino or PSoC5 modules with Python desktop monitoring and control app. Remote operation via USB Serial or Ethernet (new).
M5Stack uses the ESP32 CPU and I believe the 2nd ADC is taken over by the Wi-Fi features. This makes it necessary to use an external Wi-Fi connection, ethernet, and ADC.
IF you have Wi-Fi remote monitoring it usually does not need a local graphics screen so will move this feature to a headless version platform choice. Having both makes sense if the cost to build these was high to build/buy only 1. These are cheap though.
