EASYLINK: common questions

What microcontroller does the EASYLINK use?

The EASYLINK is built around the CH32V203C8T6, from the RISC-V family.

How big is the EASYLINK PCB?

The EASYLINK measures 87 × 72 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the EASYLINK?

118 components, from 50 distinct parts. The full bill of materials is listed on this page.

Where can I download the EASYLINK design files?

From the KrogeChen/EASYLINK repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the EASYLINK design in my own project?

The repository has no license, so all rights stay with KrogeChen. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the EASYLINK 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.
