PLEASE TRY THE NEW VERSION OF THIS PROJECT:
SOFTWARE CODE (Arduino and Nextion files):
V2 CODES from: https://s21rc.net/s21rc-ldmos-sspa-controller-v2-0/
or
V2.1.x Lite from: https://github.com/s21rc/ldmos_sspa_controller_v2.1_lite
PCB GERBER: s21rc_ldmos_controller_v1.6.zip
!! V1.x OLD VERSION - NO LONGER DEVELOPED!!
TFT file for 5 inch display uploaded.

Features:
- Arduino Nano [easy code to understand]
- Max watt, max SWR, Max Temp for Bar graph settings can be changed in Arduino code.
- Display Power output in bar graph and numeric
- Display SWR in bar graph and numeric
- Display Temp in bar graph and numeric
- Display Band in Numeric, also band button shows current display. Touch button for band selection.
- Antenna 2 selection (optional - currently no GPIO left)
- Shows FAN speed (LOW/MID/HIGH/HOT/ALRM)
- Band change by 8 pole rotary band switch (position 1 will enable touch switch).
- No Band change when TX on, if you change band switch or select different band from touch - it will change when TX goes of.
- PWM FAN control depends on temperature.
- Temp sensor DS18B20 3 pin IC
- Volt monitor.
- Current monitor from DXWORLD-E protection board (BTS.....)
- Shows SWR/High Po/High current LED status on LCD
- Shows PTT status (on air)
- Shutdown bias V at 54.9 Degree (you can set it)
- Shows operator callsign on front display (change it inside Arduino code)
- For touch band selection, band change memorize in eeprom, comes back same band after power on or reset.
If you need any clarification or help raise a "issues" here in GIT, or drop me an email.
