SparkFun Rotary Switch Potentiometer Breakout
The SparkFun Rotary Switch Potentiometer Breakout is a small board the allows you to add resistors to a 10-position rotary switch, turning it into a potentiometer with 10 discrete steps. Multiple applications require potentiometers that are hard to find due to specific resistance values or cus...
Non-Invasive Current Sensor - 30A
This non-invasive current sensor (also known as a split-core current transformer) clamps around the supply line of an electrical load to measure how much current is flowing through it. The sensor acts as an inductor, responding to the magnetic field around a current-carrying conductor, and output...
USB LiIon/LiPoly charger [v1.2]
·
This is a Lithium Ion and Lithium Polymer battery charger based on the MCP73833. It uses a USB mini-B for connection to any computer or 'USB wall adapter'. Charging is performed in three stages: first a preconditioning charge, then a constant-current fast charge and finally a constant-volta...
