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.

V 1.5 Bug fixed. Touch disabled when TX.

V 1.4 Arduino-LDMOS-SSPA-Controller-v1.4.ino Pin assignment corrected for PCB V1.1

V 1.3 Arduino-LDMOS-SSPA-Controller-v1.3.ino Arduino LDMOS SSPA controller with Nextion HMI display

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.
