RoboBrrd Brain (APMB)!

Your RoboBrrd needs a brain! Use this Arduino Pro Mini Breakout board that was specifically designed for RoboBrrd to get it up and running.

The input and output pins are clearly marked, so you will never get confused with where the servos, LEDs, and light sensors should be plugged in.

It is also much lighter than the original RoboBrrd Brain Board (but still no guarantees that it will actually be able to fly!).

Using the Arduino Pro Mini as a ‘drop in’ controller will give you flexibility with the electronics. If you need to borrow the controller for a different project, just remove it from the RoboBrrd Brain board. When you want to control RoboBrrd again, plug the Arduino back in! Simple and effective!

This also comes with an enclosure ‘sled’. Makes it easier to hot glue feathers to it. Or, for actual mounting purposes.

Already have one? Scroll down for the soldering steps!

Step 1


You will need a few female and male headers for your Arduino Pro Mini.

2x 2-Female
2x 2-Male
2x 12-Female
2x 12-Male
1x 6-Male (90 degrees)

Step 2


Solder the male headers to the Arduino Pro Mini.

Solder the female headers to the breakout board.

Refer to the image above to see which row the female headers go into. (And double check with your Pro Mini when soldering)

Step 3


Solder the additional headers in place.

4-Female: LEDs
4-Female: LDRs
2-Female: Vin->V+ PWR SEL
2-Male: Vcc->V+ PWR SEL
Shorting block: On Vcc->V+ PWR SEL
3x 3-Male: SERVOS

Step 4


Plug in the Arduino Pro Mini and corresponding breakout boards!



Here is what the final board looks like, front and back.
