KiCad
The Cad of
this take some time, first try to put in CPU on the board didn’t succeed , so the final is with the CPU module
from . Same small mistakes is now fixed, and all function is verified. The
result is a board with a lot of function. Extra Dac for AGC , 8 i/o and one UART, 4 ADC
channels this is for future use. Tested
and working is AREF analog reference for CPU module, RTC + EEPROM, VFO + BFO
(Si5351), LP-Filter (CW/SSB), Input for CW key, MIC amplifier, MIC compressor,
SD-CARD, TFT and Touch display, temp sensor, encoder and ton-generator for CW.
Connection for the earlier done board PA, LP-Filter, Frontend 02.
Next is a modified
TRX board stay tuned!
