Solar powered switch-mode charger (CN3801), protector (HY2112) and 5V booster (MT3608) for LiFePO4 batteries.
The charger provides maximum power point tracking (MPPT) and can easily be modified to work with LiPo batteries.
# 1. Overview #
Li-Ion battery charger, protector and 5V/3A booster. Use unprotected Li-Ion batteries with low internal resistance which are rated for a discharge current of at least 7A! Connect the battery with short wires of 20AWG or thicker! Attach a heatsink on the back side of the PCB when drawing more than 2A of current continuously! Use a slide switch that can withstand a current of 6A!
Li-Ion battery charger, protector and 5V/2A booster. Use unprotected Li-Ion batteries which are rated for a discharge current of at least 5A !
USB plug with 12V boost converter.

This is the MT3608. It is a exact copy of the famus MT3608 board.
It is a DC-DC step up adjustable boost converter. It can take input voltages as low as 2V and step up the output to as high as 28V. The MT3608 features automatic shifting to pulse frequency modulation mode at light loads. It includes under-voltage lockout, current limiting, and thermal overload protection.
This module has a mult...
[FULLY TESTED, but new revision coming with tweaks] An MSP430-based board including lipo charger (500mA), boost converter (5V), and wireless control (NRF24L01), to drive APA102C RGB LEDs. Each building block can be used on other boards to create a number of IoT boards.

This circuit uses the Buck/Boost Converter circuit for typically for use in a lab bench power supply. It features both adjustable voltage AND current using potentiometers.
Without a buck/boost converter,a computer power supply can only provide a 3.3V, 5V and 12 supply lines. With the buck/boost converter created with the aid of a 555 timer, adjustable voltage is allowed. A simple transistor is us...
