UPS PIco HV3.0A - Uninterruptible Power Supply for Raspberry Pi®

Pimodules has come up with a new UPS PIco with the name UPS PIco HV3.0A. The UPS PIco HV3.0A is an advanced uninterruptible power supply for the Raspberry Pi® 3 that adds a wealth of innovative power back-up functionality and development features to the innovative micro-computer! With it's pre-installed peripherals, it can be used as all-in-one tool that allows you to implement projects with ease and simplicity.

               It is specially designed for the Raspberry Pi® 3 but it's also compatible with all other models. It comes equipped with 3 User Keys, 3 User LEDs, 3 different types of high capacity batteries, 2 x 3 pins bi-stable relay (Zero Power), as also 3 x A/D 12 bit converters pre-adjusted to 5V, 15V and 30V conversion.

Power Specifications:

Pimodules have implemented a Dynamic Power Tracking feature that can automatically adjust battery charging current according to power availability ranging from  50mA – 1000 mAh. This feature has been especially designed to support Solar Panel Powering Raspberry Pi® Systems, as the output from solar panel can vary according to weather conditions. UPS PIco HV3.0A can accept external voltage input ranging from 7 V DC up to 28 V DC !! This makes it ideal for use in Cars, Trucks, Buses and any industrial applications where voltage is usually higher than 24V DC. The External Supply Powering Input is equipped with Over Current protection, Over Voltage as also with Zero Voltage Drop Inverse Polarity Protection in order to use all available energy from the solar panel.

Product Overview:

The UPS PIco HV3.0A is equipped with a standard 450 mAh 15C LiPO battery specially designed to enable safe shutdown during mains power failure. The included battery provides enough power to keep running the system for 5-8 minutes. Additionally, you can also upgrade the battery capacity to 4000mAh, 8000 mAh or 12000 mAh batteries (optional on special request). With 12000 mAh batteries on board, you can use your Raspberry Pi for more than 32 hours without a power supply connected!

The UPS PIco HV3.0A 450 mAh Stack Plus design supports 2 types of lithium cell chemistry: LiPO as also LiFePO4. LiFePO4 batteries are useful in applications where temperature environment is more restricted which can range from -10 degrees up to +60 degrees. In addition, the LiFePO4 chemistry offers a longer cycle life than other lithium-ion cells out there. It can achieve up to 2000 cycles!!

With additional Terminal Blocks Add-on UPS PIco HV3.0A 450 mAh Stack Plus offers a professional I/O connectivity for any industrial application including 12V level converter for both Serial Ports (one of them must be selected). The current supply delivered via GPIOs to the Raspberry Pi® is 2.6A. In addition to this, a independent supply of battery backed output of [email protected] mA, [email protected] mA is available for the devices connected to the Raspberry Pi®. This is useful for devices that needs to be kept on power on mode even if Raspberry Pi® is shut down or not powered (i.e, WiFi Routers, Motion Detectors, HDDs etc).


1. RTCC: UPS PIco HV3.0A comes with a integrated Hardware Real Time Clock and Calendar, which keeps time even when the system is running without access to the Network. The Hardware RTCC is backed up and powered from the integrated system battery. The RTCC current consumption is only 1 uA. The integrated Hardware RTCC enables a new extremely usefully feature – the Events Triggered RTCC Based System Actions Scheduler. The Events Triggered RTCC Based System Actions Scheduler allows to timely start up, or shutdown the Raspberry Pi® on various internal or external events that include, 1-wire, IR, A/D, RTCC, temperature, Opto Coupled Input or just on requested Time Stamp.

2. Relay: The Zero Power Bi Stable Relay offers two independent sets of NO terminals. It can switch loads up to 1A, Due to unique design, no power is required when Bi Stable Relay is in Set/Reset state, making it ideal for battery powered applications.Two independent 3 pins sets are offered (NC, NO, COM) which are switched at the same time.

3. Monitoring: You can now monitor high voltage signals safely with the Opto Coupled interface, which can be read as digital or as analogue input. It's 12 bit buffered A/D comes with built-in ESD protection. In addition, you can monitor system health such as Battery Voltage, External Powering Voltage, Raspberry Pi Voltage, Current Consumption, System Temperature and 1-wire interface.

4. IR Receiver: The UPS PIco HV3.0A 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!

5. Sound Transducer: 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.

6. Secondary Serial Port: With UPS PIco HV3.0A you can have access to a integrated secondary serial port which is compatible with both 3.3V & 5V TTL logic level. When used with Terminal Block it can support up-to 12V TTL logic level conversion. Their software driver is under development and will be delivered within 1 month after system delivery.

7. LEDS: UPS PIco HV3.0A comes with six independent LED's to inform user about system status.

Finally, the UPS PIco HV3.0A features an 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. The FAN speed is automatically adjusted according to system temperature conditions semi linearly (8 levels) from 0 % (FAN is OFF) up to 100% by increasing and decreasing rotation speed. This guarantees a always cool Raspberry Pi® with low noise level.
