When the holidays come, every manufacturer will encounter a problem: how do we add LEDs to the decoration?This Plasma 2040, Pimoroni’s latest attempt The best RP2040 board, Designed to solve this problem with reliable hardware that excludes all guess work for addressable LEDs.
This Raspberry PicoRP2040 dual-core Arm Cortex M0+ has been put into use for this unique motherboard.
Plasma 2040 is specifically designed for RGB LEDs. Whether it is WS2812 “NeoPixels” or APA102 “Dotstar”, this small board can handle them. Four screw terminals handle the data and power connection of the RGB LED. These terminals provide a powerful and reliable way to quickly connect.
A certain number of GPIO pins are also provided. We didn’t get the complete GPIO of Raspberry Pi Pico, but got analog input, debug pin, digital/PWM pin, SPI and I2C.There is also a Stemma QT connector, which shares the I2C pin of GPIO for Stemma QT from Adafruit and Qwiic connector from SparkFun.
Inputs include reset and start buttons, as well as two user-configurable buttons. The power and data connection is achieved through a single USB-C port, which is a welcome and powerful additional feature.
Since this is RP2040, you can use MicroPython, Arduino and C to write code. But to make the most of the board, CircuitPython seems to be the best choice.
We only got this board for a few hours. Within 30 minutes, we conducted a basic NeoPixel test with CircuitPython and a 1m-long side-lit “neon” RGBW NeoPixel LED.
What is the price and release date of Plasma 2040? Only time will prove everything, but we will conduct a comprehensive review of the board of directors in the near future.
