Erle-Brain 2, the newest Linux autopilot from Erle Robotics

Hi everyone, I’d like to introduce a new version of our brain: Erle-Brain 2, a more powerful unit, smaller, faster and cheaper brain for building robots and drones.

Erle-Brain 2 ships with a cost of €199, includes a quad-core Cortex-A7 with all the sensors needed to create copters, rovers, planes or even hexapods. It includes integrated optional 1080 HD 5MP camera, Wi-Fi, Bluetooth, 3G/4G networks, USB, Ethernet, I2C, HDMI and UART.

The weight of the whole system is 100g and the size is a bit smaller than his predecessor with 96 x 70 x 25mm.

Some specifications regarding the sensors included:

  • Accelerometers: MEMS digital-output triple-axis accelerometer with a full scale range of ±8g (or alternatively ±16g) and integrated 16-bit ADCs
  • Magnetometers: MEMS triple-axes 16 bit (15μT/LSB) with a full scale measurement range is ±4800μT
  • Gyroscopes: MEMS triple-axes with a full-scale range of ±1000 (or alternatively ±2000) °/sec and integrated 16-bit ADCs
  • Barometers: digital pressure sensor with 10 cm resolution

Erle-Brain 2 has been built on top of the Raspberry Pi 2. This decision has been made mainly due to its popularity and existing support for this board already. We are looking forward to collaborate with other existing options based on this exact same board. Erle Robotics delivers a close solution of a complete Linux autopilot both at the hardware and software level.
