DL0WH_BiTuner_Firmware
Based on the DJ0ABR tuner hardware this project is a replacement for the controller PCB and its firmware. The new PCB does have a STM32L476RGT6 MCU device and has got preparations for SWR metering.
V1.2 PCB after placement and routing was done:
V1.2 MCU Pinout:
Ready for samples:
The board is again ready for production.
Version list:
V1.2 SWD connector bad size - 2019-02-01
* Library content for the CORTEX JTAG/SWD connector was wrong, fixed.
* PCB board house failed on trace distances of 6 mils. Design expanded to 8 mils.
V1.1 LQFP64 bug fix - 2019-01-18
* Due to a bad LQFP64 package within the STM32L4 library (who made that crappy library?) the device did not fit at the PCB. That made a turn-around to take time and money. Never trust any library again.
V1.0 initial version - 2019-01-04
