There is a magnetic buzzer, OLED display connector, 4 RGB (bling) LEDs and FWD/REV LEDs on board. It took some time to get the motor moving, but that was due to the driver IC running at 5V, but the i2C address pin was running at 3.3V - oops. Oh, and JLCPCB are still running their $2 special for a 6-8 layer PCB, so it only cost A$9 or so for a 6 layer PCB, with epoxy filled via's and ENIG finish. Way over kill, but it sure has a nice smooth PCB!
Once I had confirmed everything worked ok, I thought it might be nice to try and squeeze another DRV8830 motor driver IC and connector onto the board, so the next iteration of the board is now in transit back from JLCPCB.
