Description

Three UNO R3-compatible boards with USB-C, a black solder mask and ENIG gold finish. The standard UNO pinout means existing code, libraries and shields work unchanged.

Highlights

• Standard UNO footprint. Same pin layout as the UNO R3, so shields and sensor modules plug straight in.
• USB-C. Replaces the old Type-B socket for programming and power, and plugs in either way.
• ENIG gold finish. Good solderability and oxidation resistance; lead-free and RoHS compliant.
• Ready to use. Headers pre-soldered, pin names printed on the board.
• Three boards. Enough for a small classroom station or several projects at once.
