The RadioMaster TX16S Replacement Main Board is the central logic unit for your transmitter, housing the primary STM32 microcontroller that runs EdgeTX or OpenTX. This genuine OEM part replaces a dead, shorted, or water-damaged motherboard, restoring full communication between your gimbals, switches, touchscreen, and RF modules.
When swapping the main board, gently release the locking tabs on all ZIF ribbon cable connectors before pulling the delicate wiring. Ensure the connections to the scroll wheel, bottom charging board, and screen are seated completely straight to avoid navigation or display errors on your first boot.
