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.
