The SA818S VHF/UHF transceiver and audio circuits have not yet been tested, even on a breadboard.
Rotator and Doppler control are in operation, but have not yet been tested on this PCB.
ESP32-S3 and peripheral schematic
This sheet shows the LCD and touch panel, DS3231 clock, ADS1115 position sensing, rotator connections, power supply, and USB OTG circuitry.
SA818S VHF/UHF transceiver and AF amplifier schematic
This sheet shows the VHF and UHF SA818S modules, PTT and antenna connections, and a PAM8406D AF amplifier. These circuits have not yet been tested.
Preliminary SatBox PCB component placement and routing
Rotator and Doppler control have been tested on a universal prototyping board, but not on this PCB. The PCB is planned to be ordered from JLCPCB.
