[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 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 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...
