Breadboard Power Supply
The Breadboard Power Supply includes AMS1117 – 5V voltage regulator and AMS1117–3.3V voltage Regulator, providing fixed supply voltages. It features three voltage input options: a screw terminal connector, DC adapter connector and USB connector. It can operate on 6-12V DC power supply and has separate screw terminals for 3.3V and 5V outputs.
The AMS1117 series of adjustable and fixed voltage regulators are designed to provide up to1A output current and to operate down to 1V input-to-output differential. The dropout voltage of the device is guaranteed maximum 1.3V,decreasing at lower load currents.
Hardware and PCB were designed with Cadsoft Eagle 7.1.0 version.
