The PIXO Pixel is an open source RGB display that uses the very cool, APA102-2020 Addressable LED in a 16 x 16 array. These LEDs are very fast, bright, and tiny; only 2mm x 2mm! Controlling the LED matrix is an ESP32 which is a WiFi and BLE connected microcontroller than can be programmed using the Arduino IDE(Or MicroPython!). Together these make up a very cool desktop display that you can program to do pretty much anything you want. There is also an added proto board for if you want to add more components like an accelerometer, thermometer, light sensor, potentiometer, anything!
I will provide a sample program to get things started, but programming will require some knowledge in programming Arduinos and ESP32*.
*This product is for advanced users who understand and are comfortable with the power requirements for such a device. See "End User" and "Power Limit Disclaimer" sections.
Don't forget sand physics!
Feel Like Building Your Own?
If you are brave enough to assemble one of these yourself and you want to. You can choose the "Bare Circuit Board + Hardware" reward. If you choose this you will receive(everything in the picture above):
- Bare Circuit Boards for the PIXO Pixel(no components)
- ESP32 Module
- 4 x Screws
- 6 x Spacers
- 4 x Bolts
What you will still need to get it working:
- Electronic components like Capacitors, Resistors etc.
- 256 x APA102-2020 LEDs
- 5V power supply with at least 5A
It will be on you to source the remaining components, but all the information to assemble the boards will be available on the HackADay.io page.
End User
The PIXO Pixel is a hobbyist level device meant for the advanced users who are comfortable with working with high current applications(Around 3A). Therefore, by purchasing this product you are agreeing that you understand that the PIXO Pixel still requires knowledge in programming and electronics and is not an "off the shelf" consumer product.
Each assembled unit will be tested and shipped working with simple example Firmware. It is the responsibility of the End User to understand the power limits of the device and program it accordingly to ensure safe and responsible usage.
Power Limit Disclaimer
You will require a power supply that can supply a current of 5V and 5A to the board. The board is fused for 3A continuously and can handle momentary 5A. Exceeding these limits can cause damage to the board. Here are some suitable power supplies:

The combined individual current consumption of these LEDs at full brightness(all on and White) is capable of pulling over 10A. The size of this circuit board is not capable of dissipating that much heat(5V * 10A = 50W). Under normal use the panel will get warm to the touch if illuminating a lot of LEDs at the same time. In the Arduino code I will provide, you will notice a "BRIGHTNESS" variable. I like to keep this under 30. As you go higher the more current the board will take. End Users must be aware of the current limits of this board.
Please Note: The End User is responsible for sourcing a suitable power supply for the PIXO Pixel. I am not liable for any damages by, or to, the unit or otherwise, through improper powering of the PIXO Pixel.
