This is a tiny module to power your hardware projects. Which consists of a Li-ion battery holder to attach the Unprotected Cap 3.7V Li-ion Battery, along with TP4056 charging module to charge the battery through a USB Type-C charger and MT3608 boost converter to boost the Voltages up-to 20V. There are two ICs the DW01A and the FS8205A for protection of the unprotected cap battery. The row of P1 headers are for choosing the Voltages between 5V, 9V, 12V, 15V and 20V to obtain these Voltages simply short the FB and the pin labled to these values up-to. There is also a SPDT Slide Switch to ON or OFF the current supply of the board from the battery. CAUTION! It is NOT generally recommended to use Voltages above 12V as this may lead to quick battery drain or an accident if any small mistake occurs, if you are using Voltages higher than 12V please double check the components and the connections.

Usage Guide

• Use a jumper cap to short the FEEDBACK and 5V-20V pin in the P1 Headers
• Use the SPDT switch to ON and OFF the Voltage supply
• Use the 3 pin Male headers to use voltage there are two GND indicated with - and a VOUT pin indicated with +
• Ensure you have put the battries in!

WARNING! Don't short more than one jumper at a time this may fry the MT3608
