Smd0201
About the Smd0201 PCB
Smd0201 is an open source RISC-V PCB design by eutectic6337, published on GitHub under the CC0-1.0 license. It is a 2-layer board measuring 40 × 40 mm, with 23 components from 5 distinct parts.
Its main chip is the WCH CH32V003F4U6, from the RISC-V family. By type, the board carries 10 diodes, 10 resistors, 2 connectors and 1 IC.
From the project
a challenge coin with blinky lights
Feature: Using 8 PWM channels to provide dimming function for 16 LEDs by connecting pairs in anti-parallel between a PWM pin and a GPIO.
built as a stack of 3 PCBs - components mounted on top of bottom board, second board has a cutout to fit a battery and for each mounted component, and top board has holes to transmit light from LEDs
finished coin to have [relatively] smooth top and bottom

Smd0201: common questions
What microcontroller does the Smd0201 use?
The Smd0201 is built around the WCH CH32V003F4U6, from the RISC-V family.
How big is the Smd0201 PCB?
The Smd0201 measures 40 × 40 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Smd0201?
23 components, from 5 distinct parts. The full bill of materials is listed on this page.
Where can I download the Smd0201 design files?
From the eutectic6337/coin1 repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Smd0201 design in my own project?
Yes, under the terms of its CC0-1.0 license, which eutectic6337 chose for the repository.
Can I test firmware for the Smd0201 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.
