This module allows you to easily supply power to your own experiments or experimental setups on breadboards. The circuit board is simply plugged on and then supplies the Bread-board with 3,3 and 5V. The voltage is individually adjustable for each side.
Additionally 3,3 and 5V and ground on pins are available. The board can be supplied with power by most mobile phone chargers due to the Micro USB port. A standard USB and a DC IN input are also available. If the DC IN is used as input source, the USB ports can also be used for power consumption. With the switch, you can select between USB or DC IN for the input source.
