The Pi16340 SMART UPS HAT

The Pi16340 SMART UPS is a small form factor power supply and Smart UPS for the Raspberry Pi 3A+ computer (Also works with other Pi's). It 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, it's Great for every project.

How It Works?

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. Once power is restored the Power Good GPIO will then go HIGH and the output terminal will be enabled powering up connected devices. The firmware on the microcontroller also filters out small spikes and brownouts on the power supply input so no shutdown is performed unless the interruption is longer than a predetermined period of seconds. Without a UPS on your computer, these interruptions can crash your Os or even corrupt your system files causing downtime and repair. The low power microcontroller reads temperature and humidity readings from a sensor and raw byte data can then be accessed from the HOST via I2C at which point a mathematical formula is applied to process the data. This is great for those applications needing environment monitoring whether it be a remote site, outdoor location or in a server room, For the IoT dongle board, we have upgraded to a powerful WROOM32-DONGLE with a DUAL CORE CPU board adding an SD card for data logging and GPIO connection to the microcontroller for Remote Reboot feature. IoT and CLOUD connections are possible along with BLE application from the ESP32 module. The Pi16340 Smart UPS HAT can be powered from a DC supply up to 24VDC and provides additional ESD and other protection circuitry from voltage spikes and other events which occur in industrial, commercial and residential applications. Pluggable terminal blocks allow quick and easy installation into your applications. Integrating the Pi16340 Smart UPS HAT into your projects ensure a safe and reliable power source to minimize downtime, protect your devices from noisy environments and allow remote operations. Various sized capacity 16340 Lithium Ion batteries can be used to increase run time or backup power for your devices. We are working on a 3D printable case which provides a solution to house your Pi16340 Smart UPS HAT along with the recently released Raspberry Pi 3A+ board.
