Tested hardware for BBBMINI

This is a list of tested hardware for the BBBMINI. If you have other hardware in use, please let me know, so I can update the list.

RC Receiver

    • Hi Mirko,

      I will test without resistors and update.


  • To use the second module IMU, it is connected in SPI_0 or SPI_1? this second module does not use GPIO to interrupt. You can add GPIO for buzzer and safety switch?


    • from the software discussion:

      "yes you are right. checkout the dual_mpu9250_ak8963 branch and connect the second imu like as the first one (but to spi port0 P12)."

  • Here's a picture of my 1.4 mod to get the Battery Voltage & Current readings.

    The output of the 3DR-clone power module goes to 2 x  10k pots. output of arm goes to AIN0 (P9-pin39) for voltage and AIN1 (P9-pin 40) for current. I soldered a standard RC connector and fixed it on the board with a small  gage wire wrapped  around connector + crazy glued.


    Set the config parameter as:


    • Hi Patrick,

      thanks for you picture - I was with trouble measuring voltage and after configuring mine like yours is working now :)


    • Cool ,

      Glad it could help :-)

  • Managed to get an ESP8266-07(with external antenna) working on my BBBmini. Just bench tested it for over an hour connected to Mission Planner - and it still works. I used the info at  https://pixhawk.org/peripherals/8266 & https://github.com/dogmaphobic/mavesp8266. To get it into boot mode I had EN - high, GPIO-0 low, GPIO-2 high, GPIO-15 low. For normal use - EN - high, GPIO-0 disconnected, GPIO-2 high, GPIO-15 low. 3.3v used. 921,600 baud rate.


    • Developer

      Great i have a pair of these dongles in the mail, keep this stuff coming!

      They are just too cheap to resist :)

    • Yeah Linus

      ESP8266  + Arduino NANO + FTDI232 = Dont leave home without it :-)

    • Jon,

      Nice job. I understand why a Pixracer user might want this but is there an advantage for BBB users vs a standard wifi mini dongle?
