Tiny-UPS 3.0 Worlds tiniest UPS with GPIO indicator

Description

Description Show Reviews Tiny-UPS 3.0 New & Improved -A tiny-sized UPS for USB devices Tiny-UPS is a compact uninterruptible power supply for 5V USB devices, powered by external Li-Ion or Li-Polymer batteries (not included). Battery size/capacity is flexiblecharge and runtime depend on the battery used. Its ideal for IoT devices and SBCs like Raspberry Pi, Arduino, ODriod, and Android boards. Mounting holes fit Raspberry Pi Zero and Adafruit ADS1115/1015 boards. Monitoring & Indicators Built-in ADC with I2C for monitoring Vin, Vout, battery voltage, and temperature. GPIO pin signals power status (high = power on, low = power fail). Green LED = Power on, Yellow LED = Charging (off when full), Blue LED = UPS active. Sample Python code available for monitoring and shutdown. Power Operation Input: micro-USB, 5V/3A recommended. Output: seamless switch to battery at 5V when power fails. A parallel power path allows simultaneous battery charging and output. Features Tiny size 3.5cm x 2.8cm (1.38 x 1.1) Use case: IoT devices, Arduino, Beagle, Raspberry Pi, ODroid, others. Output: Micro-USB or solder, UPS 5V, 3A max via micro-USB. Input: Micro-USB or solder, 5V, 3A power adapter. UPS Battery: Li-Ion or Li-Polymer batteries. Charging: max 2A, CCCV. Monitoring: GPIO for Power failure. I2C for monitoring Vin, Vout, Battery V, Temp. 3.3V pull up for I2C provided externally. LEDs: LED indicators for battery charging, UPS, Power. Safety: All electronics are turned off when battery V drops below 2.6V. Battery charges immediately when power is restored. Temperature-controlled charging. Drained battery trickle charge. Overcurrent protection. Low Drain: Charged battery remains charged for a long time. ESD/Surge: Input protected by TI Surge Protection Device. Protection for power surges and ESD. Compatibility Works with Pi Zero and full-size models (A+, B+, Pi 2, Pi 3, Pi 4, and other 40-pin HAT-compatible boards) Pi Zero: 40-pin header required for full monitoring & shutdown via Python; micro-USB cable option for UPS only Mounting holes align with Pi Zero and Pi boards (two standoffs on full-size models) Not compatible with older 26-pin Raspberry Pi boards Resources Datasheet Downloads 0 Reviews Hide Reviews Show Reviews
