Button unit grove i2c: common questions

What microcontroller does the Button unit grove i2c use?

The Button unit grove i2c is built around the CH32V003F4P6, from the RISC-V family.

How big is the Button unit grove i2c PCB?

The Button unit grove i2c measures 92.5 × 22 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Button unit grove i2c?

21 components, from 13 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Button unit grove i2c design files?

From the 74th/74th-oshw-projects repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Button unit grove i2c design in my own project?

Yes, under the terms of its MIT license, which 74th chose for the repository.

Can I test firmware for the Button unit grove i2c without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RISC-V firmware against it before you order a PCB.
