Today's 'oh crap' moment!
Latest project...piggyback for the Chinese LMX boards with an RP2040. Supports GPS for JT modes and eeprom(if ever needed). Software from G4EML and hopefully will merge my LMX2820/MAX2871 contribution once finished testing. V2 will support 5 pin GPS and pass through NMEA and 1pps (and fix footprint)
