Pi-UpTime UPS 2.0
UPS for Raspberry Pi-4 using Li-
Ion or Li-Phosphate batteries
Pi-UpTime UPS 2.0 is a new
and improved version of the
Pi-UpTime UPS. Pi-UpTime
UPS 2.0 is designed to work
with the Pi-4 or other SBC’s,
such as Odroid, Asus, Arduino
etc. Power is supplied via the
40-pin header or via the
micro-USB out port. Powering
the Pi and charging the
battery is done on the Pi-
UpTime UPS 2.0 via a USB-C
or a micro-USB connector.
Only one connector can be
used at any time for power.
The micro-USB connector is provided for backward compatibility. The Pi-UpTime 2.0
has the same dimensions as a Pi-4 (or Pi2, Pi3, etc.) and can be mounted securely on
a Raspberry Pi using 20 mm spacers for a compact, mechanically secure connection.
An on-board 12-bit ADC monitors Vin, Vout and battery Voltage for accurate
information on operating conditions. Temperature sensor below the battery provides
accurate battery temperature information. Battery charging takes place between 0
o
C
and 50
o
C. No GPIO connections or GPIO monitoring is needed. ADC provides
information via the I
2
C. Up to three different I
2
C address can be selected via jumpers
J11, J12 to avoid conflict with other I
2
C devices. Sample python code is provided for
monitoring system parameters and shutdown the system when power fails, and
battery is low. Sample code can be downloaded from www.alchemy-power.com
External connections, via solder points, are available for I
2
C, Vin, Battery and Vout.
The connections can be accessed via 2.54mm (100 mil) terminal blocks or by direct
soldering. Terminal blocks are not included. External sensors or external controllers
such as an Arduino controllers or other embedded micro-controllers can tie into the
I
2
C connection.

temperature via ADC
using I
2
C. Up to three
I
2
C addresses. 3mV
sensitivity. Sample
Python code provided.
•
Add power on/off
switch to turn off all
power to Pi. All power,
including UPS power, is
off when switch is off.
Battery charging
continues.
•
