Included hardware
The Pololu 4-Channel RC Servo Multiplexer is available in two versions:
• The assembled version [https://www.pololu.com/product/2806] ships with the headers pins
soldered in to every through-hole except the extra slave power connection pins, as shown
in the left picture below. A shorting block is included for optional use with the FAILMODE
jumper pins. The assembled version can be incorporated into an existing RC system without
the need for any additional soldering. The header pin spacing is the same as on standard RC
receivers, so the board works directly with standard hobby RC servos [https://www.pololu.com/
category/23/rc-servos] and servo cables [https://www.pololu.com/category/112/servo-cables].
• The partial kit version [https://www.pololu.com/product/2807] gives you the flexibility to choose
different connections. It includes a shorting block and two 1×25-pin male headers. These
strips can be broken into smaller strips and soldered to the board, or wires can be soldered
directly to the board for the most compact installation.
