Sean Hodgins is back again with a Make/100 project, where he will be making 100 of his PIXO Pixel ESP32 LED displays. As of this writing, 27 people have purchased on Kickstarter, so once the next 73 are sold you’re out of luck!
PIXO takes the form of a small PCB, with an array of 16 x 16 programmable LEDs on the front, along with spacers and a second PCB on the back that allows it to stand upright. Its use of an ESP32 module means that it can interface with other devices via Bluetooth or WiFi, and can be set up to display information from a variety of sources. It even includes a prototyping area on the back breadboard with pins from the ESP32 broken out, enabling you to add sensors, buttons, or other gadgets as needed.
PIXO is available assembled, and can also be ordered as a bare circuit board without LEDs. While the assembled version includes a USB cable for programming, both require you to provide a rather hefty power supply, capable of providing 5A of current at 5V to the board to feed the 256 hungry LED modules.
