BOARD LAYOUT QUICK-REFERENCE

The table below shows the intended purpose of each of the pads on the board. Detailed instructions for wiring up the board are later in the manual.

TOP OF BOARD
ESC- Battery voltage negative, wired to ESC.
ESC+ Battery voltage positive, wired to ESC.
G Ground
S1, S2, S3, S4 Motor signal outputs 1-4.
SBUS Serial receiver (SBUS, iBus, SpekSat) input. UART1. Can be used with both inverted and non-inverted protocols, but iBus telemetry and SpekSat binding don’t work on this pad. Can also be used for ESC Telemetry if you’re freaky like that.
TELE SmartPort telemetry input (inverted) UART3.
3.3/5 5v or 3.3v output for receiver. Use solder bridge on underside of board to select voltage.
+7.6 7.6v filtered output for FPV camera and vTX. Max 1.2 amps.
RX6 UART6 receive pad. Use this for non-inverted receiver input such as iBus or SpekSat. iBus telemetry and SpekSat binding work on this pad. Can also be used for other receive functions like ESC telemetry.
CAM_S Video signal input from FPV camera.
CAM_C FPV Camera OSD Menu Remote Control function. Connect to camera OSD input pin.
LED Programmable LED output pin. Usable with Betaflight LEDStrip feature. Also, can be reassigned to SoftSerial via Betaflight resource remapping feature to provide one additional UART
TX4 / RX4 UART4 TX and RX pads. TX4 is primarily intended for use with vTX remote control function such as SmartAudio or Tramp Telemetry.  UART4 is the only one UART on the board with both TX and RX pads available. If UART4 is needed for some other purpose, reassign LED pad to SoftSerial and use vTX remote control that way.
BUZZ- Negative leg of piezo buzzer.
BUZZ+ Positive leg of piezo buzzer.
VIDEO Video out to FPV video transmitter.

 

BOTTOM OF BOARD
5v 5v output for accessory devices. Max 1.2 amps total across all 5v pads.
BAT+ Main battery lead positive wire.
BAT- Main battery lead negative wire.
+5v/3.3v Solder bridge for selecting 5v or 3.3v output to receiver pad on top of board.
