Blinkt!

by Pimoroni

Eight super-bright RGB LED indicators that are ideal for adding visual notifications to your Raspberry Pi without breaking the bank!

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 all 40-pin header Raspberry Pi models
  • 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.

Simply the best and most powerful MCU on the hobbiest market at the moment. Even the arduino setup works out of the box. So far I've tested I2C, SPI, Audio, USB audio, Rotary Encoder and SDIO card libs - all work flawlessly and fantastically well. Running some audio spectrum processing the Arm CMSIS libs for a 4096 FFT takes around 412us (0.4ms) including mag squared calcultions and all the various buffer copies - amazing stuff!

As someone dealing with microcontrollers for the first time the teensy is excellent. Incredible performance for the size and while it doesn't have a massive community the examples that are part of the ide are really detailed.

Got one as soon as they were back in stock. Arrived quickly and well packaged. Couldn’t be happier with this amazing board/service!

Nice little board with quite a bit of juice and a lot of connection options. Really nice that you can use it as a USB host, and that it has pinouts for ethernet too. Haven't tested all the stuff it can do, as I mainly use mine to run a DirtyWave M8 tracker/synth.

Fast delivery & well packaged. Using the Teensy 4.1 to run the "headless" version of the M8 tracking software - works great and setup was way easier than I expected.

I have soldered on the pins, and its running on my breadboard. I probably have not yet accessed 1 per cent of what this fantastic little board can do... I'm using Visual Studio Code with PlatformIO, all seems good so far....

Absolutely wonderful card. Incredibly fast and stable. Lots of RAM and lots of flash memory. It is also possible to expand both RAM and flash by soldering circuits on the underside of the card. With good code examples and a content-rich forum. Works well to write code in both Arduino and Visual Studio. I really love this circuit

This is a high end microcontroller. The USB host interface works very well with some good examples in the library. You can solder two PSram chips on the bottom for a Whopping 16GB of ram!!

So far the board works and powers on. I'm yet to use other features on it but Very excited. Order was quick and will use this website more often
