Get multiple DC outputs and smart servo control all in one clean shield!
The BMP26T030 is a medium-power supply expansion board built for the BMduino UNO board. Simply plug in a DC adapter or an external battery pack to deliver 4 independent voltages at once (easily pick 3.3V, 5V, 9V, 12V, or 18V) through its internal buck circuit! It also includes two types of 1-wire UART servo ports, making it effortless to power and run digital bus servos for your maker projects.
This product can be directly plugged into our designed BMduino UNO development board for use. Simply align the header pins on the back of the BMP26T030 with the sockets on the development board and plug it in, without any extra wiring needed.
