Overview
5 V and 3.3 V on both breadboard rails from USB-C
The ET-A06 is built around the USB-C 5V (Rd on CC → works with any USB-C charger/port).
Designed in Dubai by ElectroTrical — the full schematic, BOM and design notes are published below.
Good for
- Breadboard prototyping
- Powering mixed 3.3 V / 5 V circuits
- Electronics classes
