E-Keychain
This is the E-Keychain, It is a programmable Keychain you can wear on almost anything. It comes with a 0.96in OLED display, An ESP-32 C3, four buttons, and a USB-C port that can be used for programming or charging. This is also my first custom PCB I've ever built, but Pcbway makes it so easy to go from design to reality.
