Bubble AI Pendant

An AI open source pendant.

What's needed?

• Seeed Studio XIAO NRF52840 - Amazon
• LiPo Battery 502030 - Amazon
• Push Button - I have used one with contacts on one side from this set from Amazon
• AWG28 wires
• Mini Hot Glue Gun

Assembly

• Print in PLA, white is preferred because it makes LED visible
• Cut the battery connector and solder it directly to the board
• Solder the button to GND and D1 (this matches XIAO Expansion Board in case you want to do development)
• Glue button to the inner panel
• Put everything to the case and then glue everything avoiding glue on the sides of the box and avoiding gluing over microphone (!)
• Put the cover on top
• If you have flashed firmware and don't want to update it you can glue the cop cover, otherwise it is recommended to keep it as is for simple access to reset button
