User Key (A, B or C). Usage is described in the manual in a proper section.
0x24
24.008
15.01.2017
Changed Battery Powering Backup activation threshold from 4.75V on 5V GPIOs to
4.65V
Remark: Now the UPS PIco HV3.0 is checking the following conditions for Battery
Power Backup activation on the following conditions:
1. Continuously Fast Falling Powering Edge Monitoring (proprietary algorithm)
2. GPIO 5V powering is unconditionally lower than 4.65V
This will help when used lower quality PSUs that are giving higher voltage drop than
should be when system is loaded.
In any case we strongly recommend using PSU with micro USB cable on the same body
with the PSU, and minimum, recommend 3A.
0x24
24.009
15.01.2017
Corrected (and activated) option with Battery Voltage measure batlevel at 0x69 and
address 0x08 informing user about It. This option was temporary (in former version of

PIco HV3.0 Plus: Corrected bug when executed command in Raspberry Pi “sudo halt”
system not goes to the Low Powering Mode when powered from External Powering
Input. Now System is going to Low Powering Mode, and cut the cable power when
“sudo halt” is executed. If “sudo reboot” is executed system restarts the Raspberry Pi.
When system is in Low Powering Mode, can be wake up if:
- any cable power applied or change their conditions (EXT, micro USB or GPIO 5V)
- Fbutton pressed

0x30
30.023
10.02.2017
Added software low pass filter to each of the PIco HV3.0 A/D converters (users and
system)
Added decimal rounding on second position after comma to each A/D Voltage
Translator readings (0x69 Registers Set). Each A/D reading converted to
voltage/temperature/current are valid on the first position after comma. Therefore the
4.16V is shown as 4.20V, 4.12V is shown as 4.10V.

System Overview
Introduction
The UPS PIco HV3.0A is an advanced uninterruptible power supply designed for the for the
Raspberry Pi® 3 (but compatible also with the Raspberry Pi 2, and Raspberry Pi Zero) that
adds a wealth of innovative power back-up functionality and development features to the
innovative micro-computer!
Offers now total 3A current from the External Power Supply or battery backup, 3User Keys, 3
User LEDs, 3 different types of high capacity batteries, 2 x 3pins bi-stable relay (Zero Power),
as also 3 x A/D 12 bit converters with pre adjustable readings to 5V, 10V, 20V and 30V
conversion (when used with Terminal Blocks PCB or separate external resistor). Now, with
additional External Supply Powering Input; that has implemented Dynamic Power Tracking;
automatically adjust battery charging current according to power availability from 100mA –
1000 mAh, to use all available energy from the Solar Panel in case of use. This feature has
been especially designed to support Solar Panel Powering Raspberry Pi® Systems, as it is
adjusting the charging battery current to available Sunning conditions. The External Supply
Powering Input is able to accept power from 7 V DC up to 28 V DC!! Thus, make it ideal for
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 protecting Raspberry Pi
System form improper usage, but due to zero voltage drop to use all available energy from
the Solar Panel in case of use. The New UPS PIco HV3.0A is an all-in-one tool that allows
implementing easy and fast simple applications as also complicated projects providing a set
of pre-installed peripherals.
The UPS PIco HV3.0A is standard equipped with a 450 mAh 15C LiPO battery specially
designed to enable safe shutdown during cabled power cut and automatic system restart
when cabled power comes back. The included battery provides enough energy to keep
running system for 10-15 minutes in case of absence of the cable power. Additionally, this can
be easily upgraded to the extended 4000mAh version, 8000 mAh as also 12000 mAh batteries
(optional on special request), which enables prolonged use of a Raspberry Pi for more than
32 hours without a power supply connected (with biggest battery installed)!
The UPS PIco HV3.0A design support now batteries with different chemistry: LiPO as also
LiFePO4.Especially the LiFePO4 batteries are addressed to applications where temperatures
environment is more restricted as can be used for supplying from -10 degrees up to +60
degrees. In addition, the LiFePO4 have a unique extremely long life of charging/discharging
that can achieve up to 2000 cycles!!
The implemented trimmed Hardware Real Time Clock and Calendar, guarantees time stamp
when system is running without access to the Network. The Hardware RTCC is backed up and
powered from the integrated system battery.
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, data available on RS232, IR, A/D, RTCC, and temperature, Opto
Coupled Input or just on requested Time Stamp.
Professional developers often need to protect their application. To support them UPS PIco
HV3.0A offers the XTEA dual path encryption (on read and write path) embedded engine that
protect the developed software with the secure code.
The UPS PIco HV3.0A 450 mAh Stack Plus offers 2.6A battery power backup for the Raspberry
Pi® via GPIOs as also 3A extended power supply, but not only. In addition is offered an
independent from the Raspberry Pi® powering, battery backed output of 5V@750 mA and
3.3V available for the user devices connected to the Raspberry Pi® that must be running even
if the mother Raspberry Pi® is shut down and not powered (i.e. USB powered HUBs, WiFi
Routers, Motion Detectors, HDDs etc). The total current cannot exceed 3A. The current supply
delivered via GPIOs to the Raspberry Pi® is 2.6A
Many applications need to have secondary RS232 in addition to the primary one offered by
the Raspberry Pi®. Until today, it has been solved by users with add-on hardware put on the
top. Not anymore!! With the UPS PIco HV3.0A user have access to integrated secondary serial
port 3.3V level but save also to be used with 5V level. This makes the developed application
cost effective and more robust
Now with additional Terminals Blocks Add-on PCB UPS PIco HV3.0A 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 Zero Power Bi Stable Relay offers two independent sets of terminals, each one offers up
to 1A contacts able to switch ON/OFF various peripherals of the developed system. 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 independents 3 pins sets offered (NC, NO, CO) are
switched at the same time and are able to relay 2 independent applications.
Now, the high voltage signal can be monitored safely with the Opto Coupled interface, which
can be read as digital as also analogue input.
The IoT developers will find useful the 3 ESD protected 12 bits buffered A/D converters as
also number of internal sensors and sensor interfaces that can be used for system monitoring
such as Battery Voltage, External Powering Voltage, Raspberry Pi Voltage, Current
Consumption,System Temperature and 1-wire interface.
Especially with the added Terminals Blocks Add-on PCB user can preset A/D converters to
scaled measure of 5V, 10V, 20V, as also 30 V with a simple jumper selection or external
resistor. In addition, the Terminals Blocks Add-on PCB offers one A/D converter followed
voltage follower with input impedance of 1M Ohm, allowing very high impedance sensors
connectivity.
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 HV3.0A including remotely ON/OFF.

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 HV3.0A 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. The FAN
speed can be manually/automatically adjusted according to system temperature conditions
linear from 0 % (FAN is OFF) up to 100% by increasing and decreasing rotation speed. Thus,
guarantees the possible lowest level of noise and always cool Raspberry Pi® 3.
