Use the USB Charger Doctor to measure the working voltage and current output for any USB port and project. This plastic dongle plugs between a USB device, and passes the data lines through. There's a 0.05 ohm resistor in line with the power pin that is used to measure current draw. The Doctor's digital display instantly reads the numbers out for testing devices such as chargers, cables, and cell phones.
You can use this device from 3.5-7VDC input voltage (although most USB devices tend to hover around 4.75 to 5.25) and up to 3A of current. It displays both voltage and current readouts. It's a very handy tool for testing USB devices, checking load levels and debugging battery chargers and boost converters.
Protect your new 7" Raspberry Pi Touchscreen with this lovely little display frame from Pimoroni! Designed with a slimline profile, it's perfect for keeping your Raspberry Pi screen upright, and at an ideal viewing angle!
Please note: Raspberry Pi Touchscreen and Raspberry Pi are not included
Pimoroni's Touchscreen Display Frame Features:
This lovely little (14.2mm) seven segment display provides excellent segment uniformity and is highly visible up to seven meters away. It's ultra bright, and provides great readability even in bright ambient light!
It has four digits and a decimal point on each digit, designed for numeric output, so you can use it to add a clock, timer or counter into your next project.
These displays are multiplexed, common-cathode. What that means it that you can use a 74HC595 or just 8 microcontroller pins if you can spare them to control the 8 anodes (7-seg + decimal) at about ~15mA each, and then connect NPN transistors or a TPIC6B595 to the cathodes to sink the 8*20mA = ~120mA maximum per digit.
This is an ultra bright RED colour.
Specifications
This product contains only the display. Raspberry Pi, case and cables are shown for illustration purposes only and not included.
The cute PiTFT got even more adorable with this little primary display for Raspberry Pi in HAT form! It features a 2.2" display with 320x240 16-bit color pixels. The HAT uses the high speed SPI interface on the Pi and can use the mini display as a console, X window port, displaying images or video etc. Best of all it plugs right in on top of your Model A+ or B+ and fits into our case quite nicely.
It's designed to plug directly onto the Raspberry Pi 2 or Raspberry Pi 1 Model A+ or B+ . While not specifically designed for Pi Model A or B,you can use it with A/B if you solder in an extra-tall 2x13 header (not included) instead of the included 2x20 header.
This design uses the hardware SPI pins (SCK, MOSI, MISO, CE0, CE1) as well as GPIO #25. All other GPIO are unused and are available on a 25-pin long breakout line. Since we had a tiny bit of space, there's 4 flat tactile switches wired to four GPIOs, that you can use if you want to make a basic user interface. For example, you can use one as a power on/off button.
Comes as a fully assembled display PCB and an additional 2x20 GPIO header. Some light soldering is required to attach the 2x20 GPIO header to the HAT but it's fast and easy for anyone with a soldering iron and solder. You can also swap the plain female header we have with a 'stacky' type that lets you plug in a hat or GPIO cable on top or a slim ultra-low-profile header.

What's going to protect your beloved Raspberry Pi from an onslaught of rainbow-coloured fusion? That's right, it's Unicorn HAT.
Sporting a matrix of 64 (8 x 8) RGB LEDs and powered directly from the Pi, this is the most compact pocket aurora available.
Unicorn HAT provides a wash of controllable colour that is ideal for mood-lighting, 8x8 pixel art, persistence of vision effects, status indications, or just blasting colour into your surroundings.
The MagPi said that Unicorn HAT was "one of the coolest HATs around"

Software
We've put together a Unicorn HAT Python library to make it a breeze to use, including lots of beautiful examples of what it can do.

Adafruit's best-selling PiTFT just got a fancy upgrade, now we have a version with a capacitive touchscreen! That's right, instead of a resistive touchscreen, which requires a fingernail or stylus, you can now use a fingerpad. The screen looks much nicer, with a black bezel and glass overlay.
Featuring a 2.8" display with 320x240 16-bit color pixels and a single-touch capacitive touch overlay. The plate uses the high speed SPI interface on the Pi and can use the mini display as a console, X window port, displaying images or video etc. Best of all it plugs right in on top!
It's designed to fit nicely onto the Pi Model A or B rev 2 but also works perfectly fine with the Model B+ as long as you don't mind the PCB overhangs the USB ports by 5mm, see the photos above. Model B rev 1 have an older layout for the I2C pins and won't be able to use the touch screen
Uses the hardware I2C Pins (SDA & SCL), SPI pins (SCK, MOSI, MISO, CE0) as well as GPIO #25 and #24. All other GPIO are unused and you can still share the I2C pins with sensors, LED drivers, etc. Since we had a tiny bit of space, there's 4 spots for optional slim tactile switches wired to four GPIOs, that you can use if you want to make a basic user interface. For example, you can use one as a power on/off button. See below for the link to get the optional tact switches, they're not included.
The screen is the same size as the resistive type so you can use this with the PiTFT PiBow or any other enclosure you may already have. We also use the same SDL device and signals so PyGame and X11 based programs can be swapped in with no changes in code.
This version comes as a mini-kit, with a 2x13 extra-tall female header (to connect the plate to the Pi) and a 2x13 male header that can be used to connect an IDC cable or cobbler from the side. The photos above also show the optional installed slim tactile buttons. The tactile buttons are not included. Some basic soldering is required to install the headers. You can also pick up an extra-long Pi stacking header if you want to install that instead of the 2x13 female header installed.
This RGB LED HAT (B) can be easily attached on top of the Raspberry Pi to display colorful effect, and controlled by only one signal pin.

Use Four Letter pHAT to display... four letter words. Not that sort!
Pi ZERO and case not included!
Four Letter pHAT has four 14-segment displays that you can use to display text, numbers, and a host of other characters. Its LEDs are a beautiful retro green, just like you old digital alarm clock. They're driven by the HT16K33 chip over I2C.
It's perfect as a readout for your projects, displaying temperatures, times, etc. and becomes really useful when combined with some of our other boards like Enviro pHAT or Explorer pHAT to display their sensor values.

Software
Our handy one-line installer will install the Four Letter pHAT Python library for you. We've included a bunch of examples too, to show off what you can do with Four Letter pHAT; things like a clock, a countdown timer, or CPU activity monitor.

Is this not the cutest little display for the Raspberry Pi? It features a 2.8" display with 320x240 16-bit color pixels and a capacitive touch overlay. That's right, instead of a resistive touchscreen, which requires a fingernail or stylus, you can now use a fingerpad.
The screen looks much nicer, with a black bezel and glass overlay.
This updated design fits perfectly onto the Pi Zero, Pi 3, Pi 2 or Model A+, B+! (Any Pi with a 2x20 connector) Not for use with an old Pi 1 with 2x13 connector. This version also has all 40 pins GPIO pins brought out so you can connect a 40-pin GPIO cable underneath.
The display and touchscreen uses the hardware I2C Pins (SDA & SCL), SPI pins (SCK, MOSI, MISO, CE0) as well as GPIO #25 and #24. All other GPIO are unused and you can still share the I2C pins with sensors, LED drivers, etc. Since we had a tiny bit of space, there's 4 slim tactile switches wired to four GPIOs, that you can use if you want to make a basic user interface. For example, you can use one as a power on/off button.
Use it for console access or easily pop up X11 onto the PiTFT for a mini monitor, although its rather small at 320x240. Instead, we recommend using PyGame or other SDL-drawing programs to write onto the frame buffer.
Raspberry Pi computer and enclosure not included! As of July 22nd, 2015 this display comes fully assembled with tactile switches too
