FIELD TESTADAFRUIT $7 adafruit.comhe Adafruit PiUART is not a HAT, or a
pHAT, but it is a really handy add-on
board for your Raspberry Pi project
that is perfect for certain situations,
especially when creating a headless
setup, since you won’t have to plug
and unplug the USB all the time when developing
your project.
You connect via a micro USB cable for power, and it
also makes a serial connection so you can access
your Raspberry Pi’s console. The board has two LEDs
to show when you’re actively connected to RX and
TX, which is really handy. And there is even a physical
on/off switch for when you are done debugging! Best
of all, this little board comes fully assembled, so you
can just plug it in and get going. Just keep in mind
this board is great for Raspberry Pi Zero and A+, but
other boards may pull too much power from your
computer’s USB port. Head over to the product page
to read more about the requirements.T

ADJUSTABLE BREADBOARD
POWER SUPPLY KIT - V1.0Need a simple way to power up your next breadboard
project? The adjustable breadboard power supply kit
from Adafruit just might be the perfect solution. Once
soldered together, you can use any DC power supply
(max of 20 V) with a 2.1 mm plug to get beautiful, and
adjustable, power to your solderless breadboard. It’s
a good beginner project that adds another functional
tool to your workbench for prototyping more Raspberry
Pi projects.ADAFRUIT $15 adafruit.comADJUSTABLE BREADBOARD
POWER SUPPLY KIT – V1.0At some point, everyone who experiments with electronics comes across an old
computer, and other things like printers and keyboards. Sometimes they can be
repurposed to serve as a network drive, or run a CNC machine, but other times they are
best used as a paperweight. It’s those paperweight computers that still may have some
useful parts, and that’s where the SparkFun Benchtop Power Board Kit really shines.
After about 30 minutes of assembly,
and a connecting it to a used ATX
computer power supply, this kit will
provide you with quick and easy access
to the typical voltages needed when
developing physical computing projects.
You will have access to four different
voltages, 3.3 V, 5 V, 12 V and -12 V. And each
will have its own replaceable 5 A fuse and
ground connector. This is a simple and
affordable way to add a lot of functionality
to your electronics workbench.SPARKFUN $22 sparkfun.comSPARKFUN BENCHTOP POWER BOARD KIT
