# Adafruit Pixie: 3W chainable LED pixel with onboard PIC microcontroller

> **Key takeaway:** Adafruit released Pixie, a 3W chainable smart LED with an onboard Microchip PIC microcontroller that handles PWM autonomously after receiving color data at 115200 baud.

## Summary
Adafruit's new Pixie LED module delivers 15 times the power of a standard NeoPixel at 3W total output. Each unit contains a Microchip PIC microcontroller that receives color commands via serial at 115200 baud and manages PWM independently. The design supports daisy-chaining with automatic message forwarding, and includes a 1-second timeout as a safety feature against stuck-on states.

## How the Pixie differs from NeoPixels
- **Power**: 3W total vs. ~0.2W for a standard NeoPixel
- **Microcontroller**: Each Pixie contains a dedicated Microchip PIC, not just an LED driver
- **Protocol**: Simple serial at 115200 baud, 1 byte per color channel
- **Chaining**: Data forwarding between pixels enables shift-register-style daisy chains
- **Safety**: Mandatory 1-second keepalive timeout prevents thermal runaway if control signal is lost
- **PWM**: Offloaded to the onboard PIC after initial color set

## Why it matters
The Pixie fills a gap between low-power addressable LEDs and high-output lighting for makers needing visible output in daylight or larger installations. The simple serial protocol may ease integration with non-AVR platforms compared to timing-critical WS2812-style signals.
