This is a basic, 4-digit 7-segment display - yellow in color. It has a common anode. The display features one decimal point per digit, and individually controllable apostrophe and colon points.

The LEDs have a forward voltage of 2.1VDC and a max forward current of 20mA. The hardware interface is sixteen (two rows of eight) through-hole pins

Simple shift register IC. Clock in data and latch it to free up IO pins on your micro.

 A basic 12 button keypad for user input. The buttons are setup in a matrix format. This allows a microcontroller to ‘scan’ the 7 output pins to see which of the 12 buttons is being pressed.

Unlock your inner Mozart with Piano HAT, a mini musical companion for your Raspberry Pi!

Piano HAT is inspired by Zachary Igielman's PiPiano and made with his blessing. We've taken his fabulous idea for a dinky piano add-on for the Raspberry Pi, made it touch-sensitive and added barrels of our trademark Pimoroni polish.

Play music in Python, control software synths on your Pi, and take control of hardware synthesizers!

Introduction

This product is an E-paper device adopting the image display technology of Microencapsulated Electrophoretic Display, MED. The initial approach is to create tiny spheres, in which the charged color pigments are suspending in the transparent oil and would move depending on the electronic charge. The E-paper screen display patterns by reflecting the ambient light, so it has no background light requirement. Under sunshine, the E-paper screen still has high visibility with a wide viewing angle of 180 degree. It is the ideal choice for E-reading.

There is a GPIO extension board for raspberry pi B+ 2B 3B, which breakout 40 pins of raspberry pi GPIO interfaces. With this board, you can easy to use the GPIO form your Pi with the Breadboard then make some GPIO control project.

Package List:

• 1 x GPIO Extension Board for Raspberry Pi B+ 2B 3B
• 1 x 40 PIN Jumper wire

Hack Your raspberry Pi!! Now that you've finally got your hands on a Raspberry Pi , you're probably itching to make some fun embedded computer projects with it. What you need is an add on prototyping Pi Cobbler from Vilros, which can break out all those tasty power, GPIO, I2C and SPI pins from the 40 pin header onto a solderless breadboard. This mini kit will make "cobbling together" prototypes with the Pi super easy. The Pi Cobbler comes with a 40 pin ribbon cable, and an assembled custom PCB with ribbon cable socket and header pins.

Need to detach or debug your HAT? Then the Black HAT Hack3r is for you!

A nifty little tool that lets you access all of the GPIO pins while also running a HAT. Ideal for debugging your HAT projects or combining a HAT with other circuits.
