The SparkFun ESP32 Thing Power Control Shield enables the ESP32 Thing to switch up to 5A of a DC load, providing a wide variety of options to control your next project! With a default voltage range of 5--28VDC, power can be connected to this shield in one of two ways. The first is the barrel connector, but with a maximum current rating of 2.5A (designed for light loads). The second option is on the 3-pin screw terminal, which has connections for VCC, ground and a 5V output. The supply voltage is regulated down to 5V to power the ESP32 Thing, as well as a fan to keep the board cool under heavy loads.
Due to a drawback with the MC33926 only possessing one current sensor per driver, we've added a feature to the Power Control Shield for loads smaller than 5A. For smaller loads, clearing the solder jumper and soldering in the appropriate feedback resistors can maximize the sensitivity of the 12-bit analog-to-digital converter (ADC) built into the ESP32 Thing. We have a full table written in our Hookup Guide below.
