The board uses the SX1276/8 chip and differs from V1.0 and V2.0 by having LED on pin 25 and Reset on pin 23. Only one definition is needed for all bands 433/470/868/915 MHz. Pin 14 used for Reset on V1.0 and V2.0 is used by the SDCard on V1.6.

I believe this code would be correct for ConfigurationManager.cpp {0x3c, 21, 22, 0, 0, 25, 1, 18, 26, 33, 32, 23, 19, 27, 5, 0.0f, "433/470/868/915 MHz TTGO T3 V1.6"}

This is the board template being used without any issues. {"name":"TTGO T3 V1.6","aADDR":60,"oSDA":21,"oSCL":22,"oRST":0,"pBut":0,"led":25,"radio":1,"lNSS":18,"lDIO0":26,"lDIO1":33,"lBUSSY":32,"lRST":23,"lMISO":19,"lMOSI":27,"lSCK":5,"lTCXOV":0.0}

Could the TTGO T3 V1.6 be added to the dropdown of supported Board Types? #135
