Introduction

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 to the innovative microcomputer!

The standard UPS PIco is equipped with a 300mAh LiPO battery specially designed to enable safe shutdown during a power cut. Additionally, this can be easily upgraded to the extended 3000mAh version, which enables prolonged use of a Raspberry Pi for up to 8 hours without a power supply connected!

The UPS PIco features an embedded measurement system that continuously checks the powering voltage of the Raspberry Pi®. When the cable power on the Raspberry Pi® is absent, insufficient, or the device detects a power failure, the UPS Pico automatically switches to the unit’s battery source. The module then continues to check the voltage on the Pi and switches automatically back to the regular cable supply when power is once again available.

The UPS PIco is powered and the battery pack intelligently charged via the GPIO pins on the Raspberry Pi®, so no additional cabling or power supply is required.

The UPS PIco is designed to be 100% compliant with HAT standards for the Raspberry Pi® B+ and A+, and is mechanically compatible with the original Raspberry Pi® models A and B when an extension header is used. In addition to this, because the UPS Pico requires no external powering and fits within the footprint of the Raspberry Pi®, it is compatible with most cases.

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!

Finally, the UPS Pico 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.

Applications

UPS PIco is equipped with plenty of features which make it an extremely useful tool for Raspberry Pi® project development. It not only provides powering continuity, but also offers extra user programmable LEDs, Sensors, buttons and I/O’s. The unit also features a dedicated 10-bit analogue to digital converter with two channels making it the perfect board for remote and unmanned sensor deployment. These extra features result in the UPS Pico being a superior all-in-one device perfect for many innovative projects, and embedded applications.

Hardware Upgrades – the PIco Add-on Boards

The UPS PIco is equipped with plenty of features that make it an extremely useful tool for Raspberry Pi® based project development. However, it can’t do everything! In order to cover a broader range of user requirements, we are developing a wide range of add-on boards that can be hosted on the top of UPS PIco. These PIco Add-on Boards will be designed to extend the functionality of the product, whilst being simple to integrate by plugging directly on top! However, in order to keep compatibility with HAT standard, each PIco Add-on Boards data will be stored in the UPS PIco HAT EEPROM. The following upgrade boards are in development and will be available soon:

*  EPR PIco Board

The Extended Powering PIco Board, will be designed to accept external powering voltage from 6 - 32V DC, and enable the use of solar panels. The device will also be equipped with various sensors, an RS232 converter, a USB interface, a bi-stable Relay and many more useful I/O’s. The EPR will of course retain the powering functionality of the UPS Pico.

* MCOM PIco Board

A Multi-Communication PIco Board, offering a multiple communication channels

including 4 x RS232, RS485, etc.

* RBT PIco Board

A RoBoT PIco Board, offering a toolset for the ROBOT projects development.

* SNS PIco Board

A SeNsorS PIco Board, offering a toolset for various sensors projects
