 The main reason for the development is to use the £5 Raspberry Pi Pico in place of the £32 FTDI USB interface on the MiniTiouner PCB.  Using the Pico interface also enables 2 channels to be decoded and displayed at the same time.
-Once proven it is envisaged that PicoTuner will replace the MiniTiouner Mk2 PCB for all new builds, however limited stock of the MiniTiouner PCB and FTDI module will be held in the BATC shop for those who wish to continue to use the MiniTiouner software which is NOT compatible with PicoTuner.
