UPDATE 17.06.2023 Due to chip shortages, we were unable to make this product in stock for 10 Months. Recently, we have prepared a new batch with some options w/o affecting the quality & output of the product. Currently, this product is in limited stock.

Overview

This is a petite integrated lithium-ion battery manager with Over Charge, Over Discharge, and Short Circuit protection. The board is designed in compact dimensions and aesthetic look of the Black Soldermask + ENIG Surface finish variant.

Why did we design it?

We as a maker frequently work with multiple voltages and we all love the popular Lithium-Ion Cells/Batteries. We work with Microcontrollers (Eg: ESP MCUs) that work on 3.3v and some popular development boards like Raspberry Pi Pico, Arduino UNO, Arduino Nano, etc that use the common 5V. Some discrete projects need 1.8V and some projects need 12V as the power supply.

We face the challenge of varying the voltage and sometimes we consider alternate boards for alternate voltages. A popular boost module on MT3608 acts friendly for us but it uses a potentiometer to vary the voltage, then we have to hot glue the pot and use it with a fixed voltage.

To solve this dilemma, We thought of modifying the electronics and making them precise with the popular voltage outputs only. We decided to use the most modern tech on this project with core components.
