LED Charlieplexed Matrix - 9x16 LEDs - Blue ESP32/ESP8279 **Note:** This battery is not

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

and OpenThread certified

The National Ambient Air Quality Standards (NAAQS) proposed that the limit concentration of ozone that humans can accept within one hour is 260 μg/m3

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

LED Charlieplexed Matrix - 9x16 LEDs - Blue ESP32/ESP8279 **Note:** This battery is notThese 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!
