Taranis X9D Hardware Connections
The following documents the hardware inside the Taranis X9D transmitter
-
LCD Display:
RMG21264-01 212×64 B&W 4-grey level display
The RMG21264-00 uses the ST7586S Driver (up to 386x160x4) but the
RMG21264-01 seems to use an ST456RB 16-level LCD driver (missing datasheet)
Radio: CC2500 (Module on board no direct access)
Digital volume control: CAT5137 on i2c BUS
256kbit EEPROM: ST M24256
