TinyLily Motor Board

DESCRIPTION When TI came out with the world’s smallest DC motor driver chip, we knew we had to build a board around it. Based around the 2mm x 2mm TI DRV8837 Motor Driver (H-Bridge) IC, this board is incredibly tiny at only 10mm in diameter, yet can drive a 5V 500mA motor!  (Note: Although the DRV8837 is rated at 11V at 1.8Amps, with the small size and small heatsinking, we do not recommend exceeding 5V at 500mA).  The DRV8837 is extremely easy to use and interface to your favorite processor board (such as a TinyDuino, TinyLily or a standard Arduino), and uses a simple PWM to control motor speed, direction, coasting and braking. The board includes a bypass capacitors and all the I/O of the DRV8837 brought out to sewtabs, as well as heatsinking the chip to a large plane on the bottom side of the board to help with heat dissipation. The TI DRV8837 has one H-bridge driver consisting of N-channel power MOSFETs to drive a DC motor or one winding of a stepper motor, or other devices like sol
