Today's digital projects require the use of components working at two or more different voltages simultaneously.
Most Arduino and compatible boards work at 5V, while sensors work at 3.3V
This simple board that takes a 7-12V input voltage and outputs a selectable 5V and 3.3V regulated voltage. All headers are 0.1" pitch for simple insertion into a breadboard.
Input power can be supplied to either the DC barrel jack or the two pin header labeled + and -. Output power is supplied to the pins labeled GND and VCC. Board has both 2 selection jumpers to select the output voltage for each output. You can select any combination: 5V and 5V, 5V and 3.3V, 3.3V and 5V or 3.3V and 3.3V
The two pairs of GND and VCC pins are spaced such that when connected to our Basic Breadboard both power buses will be powered.
The voltage regulators are good for 1A each (with thermal shutdown), but due to heat dissipation limitation, we recommend to use a max load of 250mA.
Breadboard not included.
