$20.70 / set of 3 - untested (will update)
Motor driver chip good to ~40V / 2A cont (3A pk) and power dissipation limited to 25W or by size of the (probably insufficient as designed) heatsink used.
Screw terminals and Hard Disk power connector used for convenience. Need either a jumper or Rsense across each G/S (ground/sense) terminal pair, and a 7805 ONLY if supplying power solely via +Vmotor. Pads for either PTH or SMD resistor/LED pairs on motor outputs are independent from other half of each H-bridge; BOTH will light if pulled high.
Flyback clamping diodes are DO-214AC package/pads, and should be rated for at least 2A, 40-50V.

This is a signal bus board, acting like a slotting device for ease of connection between two edge connector slots.
