Blinkt!

Description

Inspired by Alex Ellis' work with his Raspberry Pi Zero Docker Cluster, we developed these boards for him to use as status indicators. Blinkt! offers eight APA102 pixels in the smallest (and cheapest) form factor to plug straight onto your Raspberry Pi.

Each pixel on Blinkt! is individually controllable and dimmable allowing you to create gradients, pulsing effects, or just flash them on and off like crazy. The data and clock lines are connected to GPIO #23 and #24 respectively but for simplicity you can just use our Python library to drive them.

Features

Eight APA102 RGB LEDs
Individually controllable pixels
Sits directly on top of your Pi in a tiny footprint
Fits inside most Pi cases
Doesn't interfere with PWM audio
Blinkt! pinout
Compatible with Raspberry Pi 3, 2, B+, A+, Zero, and Zero W
Python library
Comes fully assembled

Software

Our Blinkt! Python library will have you blasting out rainbows in two shakes of a unicorn's tail! There's a stack of examples too, from binary clocks to cheerlights and flickering candles to Larson scanners!

Notes

Be careful to plug in your Blinkt! the correct way round, it has curves on the top that match the corners of your Raspberry Pi
If you want to access the rest of the GPIO at the same time as using Blinkt! then our Mini Black HAT Hack3r is the ideal accompaniment, allowing you to combine Blinkt! with another HAT or pHAT, or just prototype using the GPIO pins for your own project
The dimensions of Blinkt! are 65mm long x 8mm wide x 8.5mm thick (thickness includes header and pixels)
Additional accessories shown in photos not included

We featured Blinkt! on a special episode of Bilge Tank where we tried to come up with as many different code examples as possible in one morning. Check it out below.
