About the BatteryBoost PCB

BatteryBoost is an open source PCB design by stasiselectronics, published on GitHub under the CERN-OHL-S-2.0 license. It is a 2-layer board measuring 80 × 40 mm, with 40 components from 31 distinct parts.

Other key parts include the SP34063AEN, TP4056 and AP9101CK6. By type, the board carries 14 resistors, 9 capacitors, 4 diodes, 3 ICs, 3 transistors and 3 connectors.

It belongs with the power & battery designs in this gallery.

From the project

Open Source Hardware project for a battery powered DC voltage boost converter. Battery charge and protection integrated with an inexpensive Switch Mode Power Supply to convert 3.7 V to anywhere between 5 V and 24 V DC.

This respository contains the source files for a boost circuit designed to boost the voltage from a lithium battery to anywhere between 5 and 24 Volts.

The module includes a battery management system to help make recharging as easy as plugging in the microUSB cable.

This board has been designed in KiCAD, the wonderful open-source Electronics CAD software!

I have written an article on Hackster to explain some of the lessons learned while working on this design.
