Pinout

CubeBlack Board

On each connector the red dot indicates pin 1.

UART Mapping

  • SERIAL0 -> USB
  • SERIAL1 -> UART2 (Telem1)
  • SERIAL2 -> UART3 (Telem2)
  • SERIAL3 -> UART4 (GPS)
  • SERIAL4 -> UART8 (GPS2)
  • SERIAL5 -> UART7 (spare, CONS)

The Telem1 and Telem2 ports have RTS/CTS pins, the other UARTs do not have RTS/CTS.

The CONS port was originally used as a debug console, but is now a general purpose UART (debug output is now on USB).

Connectors

Unless noted otherwise all connectors are JST GH

5 (blk) SDA I2C2 +3.3V
6 (blk) GND GND

CONS port

The CONS port is an additional UART connected to SERIAL5. The pinout in the CONS port table below is ordered so that the GND pin is closest to the cube. The TX pin is closest to the servo rail.

Pin Signal Volt
1 GND GND
2 RX (IN) +3.3V
3 TX (OUT) +3.3V

SBUS Out port

The SBUSo port is a port attached to the IO processor which can be used to output all servo channels via SBUS. It is enabled by setting the BRD_SBUS_OUT parameter.

The pinout below for the SBUSo port is labelled so that GND is closest to the cube. The 5V pin on the SBUS output port is connected to the servo rail.

When SBUS output is disabled (by setting BRD_SBUS_OUT to 0) you can use the port for analog RSSI input from receivers. To enable for RSSI input you need to set:

  • BRD_SBUS_OUT 0
  • RSSI_TYPE 1
  • RSSI_PIN 103

You cannot have both SBUS output and analog RSSI input at the same time.

Pin Signal Volt
1 GND GND
2 5v(Vservo) +5.0V
3 TX (OUT) +3.3V

SPKT port

The SPKT port provides a connector for Spektrum satellite receivers. It is needed to allow for software controlled binding of satellite receivers.

The pinout of the SPKT port given below is given with the 3.3V power pin closest to the cube (pin 3).

Pin Signal Volt
1 RX (IN) +3.3V
2 GND GND
3 3.3v +3.3V

3 (blk) SDA +3.3 (pullups)
4 (blk) GND GND

FMU and IO SWD

When the case is removed there are two SWD connectors, one for FMU and the other for IOMCU. The IO SWD connector is the one closer to the servo rail. The GND pin of both connectors is the one furthest from the servo rail.

RC Input

RC input is configured on the RCIN pin, at one end of the servo rail, marked RCIN in the above diagram. This pin supports all RC protocols. In addition there is a dedicated Spektrum satellite port which supports software power control, allowing for binding of Spektrum satellite receivers.

PWM Output

The CubeBlack supports up to 14 PWM outputs. First first 8 outputs (labelled "MAIN") are controlled by a dedicated STM32F100 IO controller. These 8 outputs support all PWM output formats, but not DShot.

The remaining 6 outputs (labelled AUX1 to AUX6) are the "auxiliary" outputs. These are directly attached to the STM32F427 and support all PWM protocols as well as DShot.

All 14 PWM outputs have GND on the top row, 5V on the middle row and signal on the bottom row.

The 8 main PWM outputs are in 3 groups:

  • PWM 1 and 2 in group1
  • PWM 3 and 4 in group2
  • PWM 5, 6, 7 and 8 in group3

The 6 auxiliary PWM outputs are in 2 groups:

  • PWM 1, 2, 3 and 4 in group1
  • PWM 5 and 6 in group2

Channels within the same group need to use the same output rate. If any channel in a group uses DShot then all channels in the group need to use DShot.

Battery Monitoring

The board has two dedicated power monitor ports on 6 pin connectors. The correct battery setting parameters are dependent on the type of power brick which is connected.

Compass

The CubeBlack has two builtin compasses. One is a HMC5843 and the other is a part of the MPU9250 IMU. Due to potential interference the board is usually used with an external I2C compass as part of a GPS/Compass combination.

GPIOs

The 6 PWM ports can be used as GPIOs (relays, buttons, RPM etc). To use them you need to limit the number of these pins that is used for PWM by setting the BRD_PWM_COUNT to a number less than 6. For example if you set BRD_PWM_COUNT to 4 then PWM5 and PWM6 will be available for use as GPIOs.

The numbering of the GPIOs for PIN variables in ArduPilot is:

  • PWM1 50
  • PWM2 51
  • PWM3 52
  • PWM4 53
  • PWM5 54
  • PWM6 55

Analog inputs

The CubeBlack has 7 analog inputs

  • ADC Pin2 -> Battery Voltage
  • ADC Pin3 -> Battery Current Sensor
  • ADC Pin13 -> Battery2 Voltage
  • ADC Pin14 -> Battery2 Current Sensor
  • ADC Pin4 -> Vdd 5V supply sense
  • ADC Pin15 -> ADC 6.6V port
  • ADC Pin103 -> RSSI voltage monitoring

IMU Heater

The IMU heater in the CubeBlack can be controlled with the BRD_HEAT_TARG parameter, which is in degrees C.

Loading Firmware

The board comes pre-installed with an ArduPilot compatible bootloader, allowing the loading of *.apj firmware files with any ArduPilot compatible ground station.
