Taranis X9D Hardware Connections

The following documents the hardware inside the Taranis X9D transmitter

  • MCU: STM32F205VET6 512kB Flash, 128kB RAM 100pin package
  • 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
