With increasing use of mobile devices and growing outdoor activities, portable power banks have become increasingly popular in recent years, thanks to their convenience, practicality and affordability. YFM also provide custom solution for the device with its strong MCU resources. Here is a typical application case.

The power bank solution is designed based on the Puya PY32F003 chip of Arm Cortex ® M0+ core. The chip come with 32kbytes flash memory , 4kbytes SARM and integrates multiple I2C, SPI, UART as well as rich peripherals.

As the key part of the power bank circuit, the microcontroller works to manage the charging and discharging of the battery, monitor the voltage and current levels, and regulate the power output to the connected devices.

YFM provides full range of PY32 microcontrollers to choose from based on specific function requirement and circuit design requests. If any innovative ideas in mind, let us help to bring it to life!
