The microcontroller board I use for most of my projects is implmented using a PIC from Microchip. The processors I’ve selected are from the PIC16F1777/8/9 family since they seem to be the 8 bit PICs that have the most options for interfacing to analog circuitry.
Wireless connectivity is implemented using the LoRa standard. I chose this since I don’t need a lot of speed for simple PIC applications and the excellent link budget is really nice for home projects. I’m using a now unavailable transceiver board that is essentially a direct interface to the Semtech SX1280 chip with the RF front end and on-board antenna.
Aka daughter boards (haha). These boards plug into the PIC brain board using headers.
