Switch a battery-powered load from a microcontroller using this MOSFET Power Controller. A JST connector accepts the battery, and input pads connect to a digital control signal. Sewable pads also support e-textile assemblies, providing an interface when the intended load needs more current than a controller pin can directly supply.
