The 7Semi Eden Mini is a compact and cost-effective microcontroller board designed for advanced users who need flexibility and minimal onboard components. Built around the ATmega328P, it delivers core Arduino functionality in a stripped-down form factor, making it suitable for embedded and semi-permanent installations.
Unlike typical development boards, the Eden Mini does not include onboard USB or pre-soldered headers. This allows users to choose custom connectors or directly solder wires, depending on project requirements. It is ideal for integrating into products, installations, or space-constrained designs.
The board supports programming via an FTDI interface and comes with a pre-installed bootloader, enabling easy code uploads using the Arduino IDE without requiring external programmers. It also supports auto-reset when used with compatible FTDI breakout boards.
