UPS PIco HV3.0B+ HAT – Uninterruptible Power Supply for Raspberry Pi® 3 Model B+


The UPS PIco is an advanced uninterruptible power supply for the Raspberry Pi that adds a wealth of innovative power back-up functionality and development features. The latest version UPS PIco HV3.0B+ is especially Designed for the New Raspberry Pi® 3 Model B+. The UPS PIco HV3.0B+ HAT Advanced 450 will automatically shut-down your Raspberry Pi® if there is a power failure, supply mobile applications from battery source, and can be set to automatically monitor and reboot your Raspberry Pi® once power has been restored! It is equipped also with an Intelligent Externally Accessed (with Files Safe Shutdown) Slide Power Switch that allows to safety System Switch ON/OFF whenever you like, without worrying about files corruption as it is always properly shutdown the system before cable power will be disconnected. The new version also allows you to charge (optionally) the battery when Raspberry Pi® 3 Model B+ is OFF however still connected to the micro USB cable powering source.

For the ones who are interested in programming, UPS PIco HV3.0B+ HAT Advanced 450 offers 3 User Programmable Keys, 3 separate User programmable LED’s with different colors, support for multiple and different chemistry of a high capacity batteries, bi-stable relay (latching, Zero Power) configured as 2 Amp DPDT, and 3 independent ESD protected 12 bits buffered A/D converters. Professional developers often need to protect their application. To support them UPS PIco HV3.0B+ HAT Advanced 450 offers the XTEA dual path encryption engine that protect the developed software with the secure code.

The UPS PIco can also be equipped with an optional Infra-Red Receiver which is routed directly to GPIO18 via the PCB. This opens the door for remote operation of the Raspberry Pi and UPS Pico!.The embedded Electromagnetic Programmable Sounder can be used as a simple buzzer but also as music player due to implemented sound generator and dedicated programmer interface. Finally, the UPS PIco HV3.0B+ HAT Advanced 450 features an implemented Automatic Temperature Control PWM FAN controller, and can be equipped with a micro fan kit, which enables the use of the Raspberry Pi® in extreme conditions including very high temperature environments.
