Power Erle-Brain2

Erle-Brain2 is typically powered via its “power” port, as shown in the picture below. The power port simultaneously powers Erle-Brain2 and reads voltage and current analog measurements.

Warning

Always use a power module to feed Erle-Brain2 while flying your drone

Connect remote control inputs

Erle-Brain2 is compatible with PPM remote control (RC) receivers. For traditional single-wire-per-channel (PWM) receivers a PPM encoder can be used to convert the receiver outputs to PPM-SUM.

For more information see Compatible RC Transmitter and Receiver Systems (Erle-Brain 2).

GPS+Compass

The uBlox GPS + Compass Module is the recommended GPS for Erle-Brain2. The GPS port is connected with the six-position DF13 cable, and the Compass port is connected to the I2C port with the four-position DF13 cable, as shown in the wiring chart above.

Note

Be aware of how you connect ESCs wires to PWM rail. The signal wire (white or orange color) should be connected at the top, the ground wire (black or brown color) at the bottom.

For planes connect the control channel wires to the main output signal pins:

  • Pin 1 = Aileron
  • Pin 2 = Elevator
  • Pin 3 = Throttle
  • Pin 4 = Rudder

USB ports

Erle-Brain2 has four USB ports. Some of the devices you can connect are listed in the following section.

WiFi dongle

Use a (regular or high gain) WiFi dongle to create a hotspot that can, for example, be used for sending telemetry data and commands to a Ground Station. Erle-Brain2 automatically generates a WiFi hotspot when the dongle is connected.

Note

Edimax AC (regular and high gain) are the officially supported dongles. These can be purchased from Erle-Brain with your autopilot/vehicle.

Bluetooth dongle

Use a Bluetooth dongle to connect additional devices, such as joysticks.

Note

You will need to configure BlueTooth interface to make it work

Connect other peripherals

Depending on your hardware there may be any number of other peripherals attached, including sensors, cameras, grippers etc. These can be found as sub-pages of the topic Optional Hardware.
