Channel Breakout, Power Breakout Boards

 

Power Breakout Board, comes with mosfet polarity protection. No onboard regulator, intended for projects that have a dedicated high wattage supply already (no puny 7805).

 

 

Channel breakout board, supports up to 16 ports (Supports servos too), and powered by the connector on the right hand side, therefore you can power them off their own dedicated supply.

Biped Howto: Moving servos

+++ UPDATE (12-march-2014): Rename title as "Biped Howto".

Hi, I will try to explain, in a very simplistic manner, the way in which servo motors can be controlled.

Servo motors are controlled by a PWM signal, in which the active part of the signal (known as duty cycle) define the amount of degrees the servo will rotate.
