H-bridge board has all the transistors of the original board on it for 4 full H-bridges that can drive all of the four bi-directional motors.

Layout is as follows , with the connectors of the motors facing you:

• First block, gpio18, w1, gpio4, w7, Left tread
• Second block, gpio17,w0, gpio23,w4, Right treads
• Third block: gpio27,w2, gpio22,w3, hip
• Fourth block: gpio24, w5, gpio25,w6, arms
