“A cute PCB alpaca with a rainbow tail and glowing cheeks.
I’ve recently heard of the Micronucleus bootloader for the ATtiny85 and I wanted to try it out, so I designed this quick alpaca ATtiny85 dev board, which can be programmed directly through the USB, no other chip needed. Pretty cool!
This project is inspired by the following links:

The LED on the alpaca tail is a colour changing RGB LED and for the blushing effect of the cheeks I’ve used regular pink LEDs which I’ve reverse-mounted on the back. The cheeks LEDs are connected to pin PB0 of the microcontroller, which is a PWM pin. All the other unused pins are exposed on the back.”
