SSTV board for 2m band (144.500 MHz in Poland) in PC104 form factor.
Filter for 144.500 MHz - SA818 (and DRA818) is noisy
LEDs: :blue_circle:(power), 🟢(ok), 🟡(warning), 🔴(failure, NOT power indicator)
TO DO:
- add switch? remove-before-flight? to power on board
- check circuit for time delayed start of MP3
- add LED indicators for UART MP3?
- add JST? connector for li-pol battery - for now support only for single 18650 cell (dimension needed)
- rearrange elements on PCB to have standalone SSTV module after EOF
- where put u.FL connectors, soldering pads for antenna?
- additional filtering on MIC line?
- doublecheck pull-up and pull-down resistors
