From the project

🛡️⚡🔋🔌📱An Arduino UNO shield that makes the board portable and USB-C compatible. Made in KiCad

A shield that you can use to upgrade older Arduino UNO boards such that your projects don't need extra batteries nor cables. Just the one your phone uses!

Ever had a project that needed the arduino to be mounted somewhere such that a USB connection couldn't have been possible? I did.

I build it by integrating both a standard Li-ion charging circuit (MCP73831 reference design) with a boost converter topology and a USB-serial interface. Added my own custom changes to these, such as the LED and battery switch. It has been a wonderful experiment.
