Adafruit 16x8 LED Matrix Driver Backpack - HT16K33 Breakout

Adafruit 16x8 LED Matrix Driver Backpack - HT16K33 BreakoutThis is the magic sauce in our 7 segment and matrix backpacks, now available in breadboard friendly breakout board format. The HT16K33 is a neat little chip that has the ability to drive a multiplexed 16x8 matrix (that's 128 individual LEDs). The communication protocol is I2C so it uses only 2 pins, and you can have up to 8 selectable I2C addresses so thats a total of 8 matrices, each one controlling 16x8 LEDs for 1024 total LEDs. Unlike our LED

Build a wireless Qi charger

Wide band coverage to all popular RF frequencies

And it's still very small at just 11

Average noise level (typical): -100dBm

CTs measure AC and are useful for measuring whole building electricity use/generation

This results in a change in resistance that corresponds to the distance from the top of the sensor to the surface of the fluid

to feel the touch or proximity of human being fingers

it seamlessly integrates with our range of solar-power-compatible boards

" We have full wiring diagrams and working Arduino library code with examples from drawing pixels

Max current draw per RGB LED: ~60mA (20mA max per Red

you'll probably end up being very happy with the basic control system that the dial allows
