LED Charlieplexed Matrix - 9x16 LEDs - Blue ESP32/ESP8279 It uses an industrial-grade superpower

It uses an industrial-grade superpower anti-jamming chip inside to intelligent discriminate circuit and automatically senses the direction of data flow

Note that the battery voltage can be as high as ~21V so a buck converter such as this one could be good for getting the unregulated Vpwr from 20V down to a more reasonable 5V

Due to a drawback with the MC33926 only possessing one current sensor per driver

**Note:** This battery is not available to ship to Alaska or Hawaii

Using the 8Ch/24MHz Logic Analyzer with sigrok

LED Charlieplexed Matrix - 9x16 LEDs - Blue ESP32/ESP8279 It uses an industrial-grade superpowerThese are 9x16 Charlieplexed LEDs designed to match with the Adafruit 16x9 Charlieplexed PWM LED Matrix Driver IS31FL3731 . You don't get any resistors or driver chips with this grid, its just a mess of LEDs in a charlieplexed arrangement This is the Blue version . Check out our other colors!
