bbbmini pcb

About three months ago Mirko Deneke introduced the BBBMINI  a DIY Cape for the BeagleBone Black.

The BBBMINI should make it easy to start with Ardupilot running on Embedded Linux. It also keeps the DIY spirit, so it has no SMD parts to solder and only 0.1” pinheader to connect external hardware. So you do not have to struggle with DF13 connectors if you want to change the cable pinout.

Mirko got good feedback and decided to make things easier which seems some people stuck with, when they build a BBBMINI.

The first thing is wiring a BBBMINI up on a Proto Cape board. It is prone to errors and remote support is difficult. The Proto Cape wiring is also not so reliable. So he sat down and designed the BBBMINI PCB.

BBBMINI PCB:

  • 0.1” / 2.54mm pinheader
  • Use GY-9250 and GY-63 sensor breakout board
  • Free SPI connector for additional sensors like a second IMU, …
  • Free I2C connector for additional hardware like external Mag, LED Controller, Ultrasonic Rangefinder, …
  • Free UART for additional hardware like Telemetry Radio or second GPS
  • CAN Bus TRX so BBBMINI is UAVCAN ready
  • 12 PWM OUT
  • Extra PWM OUT for X-Quad
  • 1 RC IN

There is now a Rev 1.2 version of the PCB which fix a power issue of the Rev 1.0. After successful testing  all necessary files will be released on the BBBMINI GitHub page.

Also there is now a prebuild Image which you just write to a sdcard and direct boot from the sdcard with RT-Kernel and Device Tree already loaded at startup.

Debian 8 with BBBMINI support:

  • GCC 4.9 so you can compile Ardupilot direct on the BeagleBone
  • Kernel 4.0.4 RT PREEMPT already installed and loaded at startup
  • Device Tree for BBBMINI already loaded at startup
  • Further information is available on the BBBMINI GitHub page.
