We generally recommend using a 4- or 5-cell NiMH or NiCD battery pack to power the switch. The battery pack will typically be connected to an RC receiver or servo controller, which passes the power on to the RC switch.
The included relay is an Omron G5LE-14-DC5 (1MB pdf) and is rated for up to 10 A under most conditions.
The Pololu RC Switch with Relay is available in two versions:
- The assembled version ships with the 5V Omron relay, header pins, and terminal block soldered in. A 1×2-pin male header and a shorting block are also included with the assembled version and can be used to configure the device. The assembled version can be incorporated into an existing RC system without the need for any additional soldering.
- The partial kit version gives you the flexibility to choose different connections. It includes a 5V Omron relay, 0.1″ 12-pin male header, a 0.1″ 12-pin right-angle male header, a 3-pin terminal block, and a shorting block. These strips can be broken into smaller strips and optionally soldered to the board, or wires can be soldered directly to the board for the most compact installation.
Warning: When soldering the terminal block into the partial kit version, be sure to use the larger set of holes. If you use the smaller holes, which are intended for 0.2″ male header pins, there will not be enough space to mount the relay.
