Adafruit NeoDriver - I2C to NeoPixel Driver Board - Stemma QT

NeoPixel LEDs offer a straightforward way to add addressable RGB lighting with a single GPIO pin. However, using them with certain single board computers can be challenging due to timing requirements. The NeoDriver board is a practical solution, utilizing an ATtiny1616 chip for seamless timing management.

Specifically, the NeoDriver transmits NeoPixel data over I2C, providing perfect pixel timing. It supports up to 512 pixels, and the 5V charge-pump ensures clean signal output on 3V boards. While the I2C may not deliver rapid updates for an entire strip, an 800KHz or 1MHz clock allows for efficient use.

Benefits include pre-soldered terminal blocks and Stemma QT plugs for a solder-free setup. The default I2C address is 0x60, adjustable from 0x60 to 0x67. This board ensures hassle-free integration of NeoPixels with any I2C-equipped device.
