Earlier this month a Raspberry Pi UPS board was successfully launched via Kickstarter the form of the Pi16340 Smart UPS design for the Raspberry Pi 3 A+ but will also support other Pi mini PC systems. Created by Canadian electrical and electronics engineer Mark Chin, the small form factor power supply and Smart UPS for the Raspberry Pi can be used with various sized 16340 Lithium Ion batteries allowing you to tailor Battery’s capacity to your application.
The Pi16340 Smart Raspberry Pi UPS uses a smaller 16340 form factor Li-Ion battery which provides additional run times when power is lost or for remote applications. With a fast switchover and options for Industrial grade 24VDC power or 5V USB power to supply the UPS. Creator Chin explains a little more about the inspiration behind the Raspberry Pi UPS.
“We felt the need to make a smaller compact version of our UPS for IoT and IIoT applications. This version fits perfectly with the Raspberry Pi 3A+ computer. UPS’s are very essential to computers and the embedded world especially with the advent of IoT and IIoT applications. Sensitive data loss, system corruption and recovery time after a power loss, spike or brownout can be eliminated with the use of a reliable UPS system.”

“The Pi16340 Smart UPS HAT operates the same as its predecessors and integrates additional features for standalone operation and environment monitoring. Sold separately, our WROOM32-DONGLE board adds a powerful Dual Core CPU providing Wifi and BLE features for Web and IoT integration along with data logging and Remote-Reboot.The Pi16340 holds a single cell lithium Ion 16340 form factor battery which should have an integrated battery protection circuit. The boost circuit maintains the voltage to the Pi at 5.1V for battery voltages of 3.7V to 4.2V. The jumper allows you to disable power to the Pi and Isolate the battery circuit or start the Pi. It also includes a charging IC which can charge up to 200mA from the terminal block input connector.
Battery monitoring is achieved with the TI MSP430 FRAM ARM CORTEX programmable microcontroller which can be operated in two modes with the MODE SWITCH. MODE 1 allows the user to poll the Power Good GPIO which is high when power supply is present and goes LOW after a specified time when absent, subsequently then power is cut to the output terminal after approximately 20 seconds OR MODE 2 to ignore power supply input level and run from battery power until a pre-determined level is reached at which time the Power Good GPIO will go low and approx 20 seconds after that the power will be turned off on the output terminal giving the HOST time to perform a proper shutdown and avoid any data or Os system corruption. “
