Espruino 1.4 - Open Source Javascript Microcontroller _RPI_ARC_HAT 5 Volt Buffer For WS2812/NeoPixel

5 Volt Buffer For WS2812/NeoPixel LED Projects

12" of copper tape

there are 4 slim tactile switches wired to four GPIOs

Each one has ~18mA constant current drive so the color will be very consistent even if the voltage varies

Some light soldering is required to attach the through-hole headers to the PCB for plugging into the Arduino as well as the terminal blocks for the speakers

Espruino 1.4 - Open Source Javascript Microcontroller _RPI_ARC_HAT 5 Volt Buffer For WS2812/NeoPixelTry the JavaScript of things with the Espruino the world's first open source JavaScript microcontroller! This little board has an STM32 microcontroller pre programmed with Espruino all ready to go so you can start playing with Javascript microcontrollers. Warning: if you only use Assembly and think that even embedded C C++ is for wimps, this device might explody your head. The Espruino is a tiny computer with a JavaScript interpreter, allowing for
