ith the Wide Input SHIM from
Pimoroni, you simply supply a
3 V to 16 V DC voltage in via a
centre-positive 3.5 mm barrel
jack connector, or the +/- pins
on the SHIM, and it can
provide 5 V/2 A output for your Raspberry Pi.
That’s really handy when you need power from a
specific source, like your car’s 12 V system or other
non-5 V power supply.
The SHIM comes with a 2×6 female header, which
requires a little simple soldering, a 3.5 mm OD male
to 5.5 mm OD female adapter cable, and a 3.5 mm
OD male to tinned wires cable, which makes getting
up and running really simple and fast.he LiPo SHIM from
Pimoroni enables
you to quickly add
a LiPo battery to
your Raspberry Pi
project for simple
portability. The SHIM is so small, it’s
perfect for adding discrete power to your
Raspberry Pi Zero, but will work with other 40-pin
varieties too. Pimoroni chose the TPS61232 step-up
boost converter from Texas Instruments, which
provides up to 96% efficiency. There are on-board
LED indicators for power and low battery, making it
very easy to use. Keep in mind this SHIM will not be
able to charge the LiPo battery. It’s a trade-off for
being so simple, affordable, and small.W

The Pololu Pushbutton Power Switch is a simple, yet
fairly sophisticated, power control alternative to using
a bulky mechanical switch. The main advantage is
having a push-button-based latching power control
that allows for one push to turn on the power and
another push to turn it off. This version (see the
website for more options) operates from 2.2 V to 20 V
and can deliver a continuous current up to 6 A.POLOLU $3.95 pololu.comMINI PUSHBUTTON
