The Turnigy 1/16 BLDC Buggy makes a good donkeycar platform so I made some parts for it. There are no mounting holes for a PCA9685 because I’m using a Teensy( on a JHat ) to not only emulate the PCA9685 but also to read the RC receiver signals and present a USB joystick device so I can use the stock RC transmitter to drive/control.
