What is it?

The Icon64 is built around the ESP32 WROVER B micro controller module. It boasts 64 individually addressable WS2812b RGB LEDs. This means you can draw beautiful symbols onto its front face. But that’s not all! The Icon64 also features a MAX98357a amplifier that drives a 4Ohm on-board speaker. This component assembly makes the Icon64 the perfect device for any use case that requires wireless optical and/or acoustical signage.

Powerful Hardware

The Icon64 is built around a powerful micro controller, the ESP32. This controller has two cores running at up to 240MHz. This powerhouse lets you decode MP3 streams at the same time as calculating the frequency spectrum with the Fast Fourier Transformation (FFT) algorithm.

But the ESP32 is not only powerful, it also good with communication. The integrated WiFi module lets you connect the Icon64 to your local network or even the internet. Alternatively, you can also use the Bluetooth module to connect the Icon64 to your smartphone. Easily build a Bluetooth loudspeaker with just a few lines of code.

AppFairy - The Icon64 AppStore

You can program the Icon64 to your own needs, but you don’t have to. It comes with the Bluetooth Loudspeaker firmware pre-installed. Do you want to try out another application? No problem, our AppFairy has you covered.

Made for Makers

ThingPulse devices are always open for extension applied by you. You can program the device over the integrated CP2104 chip conveniently in C/C++, Lua, Micropython or any other language which supports the ESP32 microcontroller. We provide sample applications for C/C++ on the Arduino platform to get you started in no time. These sample applications show you how to use the LEDs or the integrated DAC.

But the Icon64 is not only great for your software ideas. We made 19 GPIO pins available in a 2.54mm pitch on the PCB. Together with 3V3, GND and VUSB this lets you add your own extensions easily. Do you want to add a CO2 sensor? No problem. We are curious about what you will build with this flexibility!
