avr usb rgb led fob
Uses firmware-only USB interface called AVR-USB.
Circuit is essentially what's on the AVR-USB page.
Plus has ISP connector for reprogramming or using the port pins the ISP uses.
Also has a 6-pin female header, with 3 pins connected to 220Ω resistors for direct connection of an RGB LED. One pin for ground. And the other two pins are connected to the RX/TX lines so you can use the USART.
Current firmware is a multi-channel software PWM LED driver.
