This project was made as a challenge to see how small I can go with conventional soldering techniques, this uses an Attiny85 with a QFN-20 package.
Este es un proyecto para ver que tan pequeño podía diseñar un circuito y culminarlo con soldadura convencional. Usa un Attiny85 con empaque QFN-20.
NeoPixel led strip controller, designed especially for led suits. It can:
- display animation - sequences of frames at regular (given) interval,
- switch animations on MIDI event - note on/off, velocity used for brightness adjust,
- MIDI over UDP over WiFi (UDP broadcast so far, but i'm working on multicast),
- use regular SD card to storage animations.

Cascade-able 5 Chip Neopixel board suitable for decorative lamps especially using the ESPEasy NeoFlame plugin.
Should work well with any Neopixel application that is suitable for groups of five LEDs.
This board is for individual WS2812b LED chips. Not the ones pre-mounted on a heat sink pcb with resistor and capacitor already installed.
The lates update is replacing IRF9540 with AO34I9L in tiny SOT23-3 body. I ran a test on a prototype for a few hours with maximum brightness. AO34I9L works just fine, I didn't noticed temperature raise.
This is a second version of Christmas Tree Controller. It is using Arduino Pro Mini and two TLC5940
For LED wiring refer to "Christmas Tree LED Wiring" project, LED v2
