MuHack SAO 10th annyversary

WIP - Expect some changes

All the file for this project are available on the Github Repo

For the 10th anniversary of the MuHack hackerspace, I made a little SAO that can also be pinned to your shirt or backpack, working off a button battery.

Features

• Two configuration: SAO and pin
• Two led mounted on a transparent parte of the PCB
• I2C interface for connecting a little SPI flash memory
• Gold plated for a neat design
• Clasp Butterfly Pin

Getting Started

This PCB is designed to be used in two different configurations: as a pin or as a SAO.

The pin configuration is the simplest one, with only two LEDs and a switch to turn them on and off, everything powered by a CR1220 battery.

There is also a solderable zone for adding a Clasp Butterfly Pin to the PCB, so you can wear it on your shirt or backpack.

BOM for PIN configuration

• 2x 0805 LEDs
• 1x CR1220 battery holder (like the Keystone 3002)
• 1x CR1220 battery
• 1x 0805 1k resistor
• 1x Switch for turning on/off the LEDs (like the C&K PCM12SMTR)

BOM for SAO configuration

• 2x 0805 10k resistor
• 1x SPI SOIC-8 flash memory (like the Winbond W25Q32JVSSIM)
• (optional) Everything listed in the PIN configuration BOM except the battery and the holder

Do not use the SAO configuration with the battery inserted, it could damage the circuit or the connected Badge!
