SpookyDuino Uno (Halloween)

SpookyDuino UNO

My entry for the 2025 Halloween contest

I designed this clone of the Arduino Uno board trying to keep it as simple as possible while not removing useful features. Unlike a lot of other clone boards this still uses a socketed Atmega328 chip, which is easier to remove and replace if necessary.

Features:

- USB type A socket for power and to upload sketches

- CH340C USB to serial converter

- ICSP header

- RX/TX leds + an extra LED on pin 13 like the original Arduino board

- Barrel jack for up to 12V input power

- Reset button

And of course it features colorful silkscreen with a Halloween theme!
