Communications

You could use a dongle WiFi to create an hotspot using Erle-Brain 2. This way, you don't need using wires to connect the device. Erle-Brain 2 is pre-configured to create an WiFi hotspot in the 5GHz bandwidth, in order to be able of using together 2.4GHz RC and WiFi.

The WiFi can be used for communicate with the autopilot, transfer files such as logs, plan a mission using a GCS (Ground Control Station), enable video streaming even control the drone.

You could plug an Ethernet wire to Erle-Brain 2 to have Internet access. You can use a internet access to install new software or to access the brain from your local network, this allow to communicate with other devices.

Erle-Brain 2 by default will obtain an IP address from the network DHCP server.

First at all, remember that you need to copy the image into the microSD Card. If you don't know how to do it follow this instructions:

Then, plug the microSD card with the image you want to run into the microSD slot. The microSD card should have been flashed correctly.

If you wish to work under Erle-Brain 2 as standalone device, is possible to do it! You will need a screen with HDMI port, an USB keyboard and an USB mouse.

Erle-Brain 2 has 12 channel of PWM output. Each channel has 25 mA current sink capability at 5V. In these channels, the most typical devices that you could connect are: ESCs, servos, gimbal servos,... The PWM can be used for powering the system, refer to Power section.

The next image show which are the PWM channels (In red channel numbers):

The top row (~) provides the PWM signal, the center (+) provides 5v and the bottom (-) is the GND signal. Make sure you plug the device connector in the right way.

If you wish to plug a game console control, you could attach a BlueTooth dongle and use this communication technology.

The radio control receiver must be connected in the channel 14 rail, as shown below:

Be caution when disconnecting devices from DF13 connectors, the first times connectors could be stiff.

The Erle-Brain 2 contains two I2C bus connectors, which gives access to the I2C bus. In this bus you could connect lots of different sensor and devices, i.e.: compass, gas sensors, temperature sensors, ...

Copter/Plane/Rover support sharing information with a ground station (or transmitter) using telemetry.

If you wish to use a telemetry device in Erle-Brain 2, you have two ways of attaching it. You could use the UART port to attach it:

If you connect the telemetry into UART port, in the autopilot launch file put here (to connect to GCS):

$APM_BIN_DIR/ArduCopter.elf -A udp:127.0.0.1:6001 -C /dev/ttyAMA0 $FLAGS

Or you could plug it to one of the USB ports:

If you connect the telemetry into USB port, in the autopilot launch file put here (to connect to GCS):

$APM_BIN_DIR/ArduCopter.elf -A udp:127.0.0.1:6001 -C /dev/ttyUSB0 $FLAGS
