Pretty Good Cheap Power Supply Unit – PGCPSU. Get the best tiny power supply for your battery powered projects!

PGCPSU is a three in one power supply board: it integrates a lithium battery charge management circuit with 5V and 3.3V DC-DC converter-based output rails to power most projects in a very compact form factor. We took special care in selecting inexpensive yet well-fitting parts to make up for a great little power(ful) supply!
