Tiny-UPS provides full UPS functionality for 5V (USB) devices. Use a Li-Polymer or Li-Ion battery to get the UPS functionality. Tiny-UPS is an ideal power source for IoT devices and Single Board Computers (SBC) such as Raspberry Pi, Arduino, ODriod™, Android devices and other USB devices. Mounting holes allow Tiny-UPS to be mounted on a Raspberry Pi-Zero as well as the Adafruit™ ADS1115 (or ADS1015) ADC boards etc. Recommend using Nylon mounts. Metal screws may cause a short circuit due to varying size of metal screw-heads.
On-board ADC reports operating conditions (V-in, V-out, V-battery, board Temperature) via I2C. Alternately, a GPIO indicates when power has failed. Based on that a shutdown routine can be triggered at a future time, based on battery capacity and power consumed. USB lines are passed through, allowing full functionality of USB port. Tiny-UPS 3.0 thus is an in-line UPS to USB. Alternately, V-in (power in) and V-out (UPS) can be soldered on to solder points provided. Terminal block allows battery to be connected conveniently. Make sure polarity is preserved.
Needed a UPS for a Raspberry Pi-Zero with good 5V regulation and up to 2.6 Amps while operating. Also needed to know operating conditions (as with Pi-UpTime and Pi-Z-UpTime) to ensure proper operation of the SBC.
Some soldering required for alternate power (non-USB) connections. Sample Python code is the same as with Pi-Z-UpTime 2.0. Please download that sample code.
