A little while ago, I wrote about WCH CH32V307 32-bit RISC-V MCU that was found in a board with eight UART ports that could be controlled over Ethernet or USB, and the company has released some source code to use the board while inviting the community to submit pull requests to the project.
But now WCH, RT-Thread, LCSC, and EasyEDA have joined hands to launch the RISC-V design challenge where the companies will provide a free board or two RISC-V chips to selected participants, as well as cash prizes with up to $1000 offered to the best projects.
The companies have prepared 300 boards and 200 chips for this contest. All you need to do to get a chance to get either one CH32V307V-EVT-R1 development board or two CH32V307 RISC-V microcontrollers is to enter your contact and project details in this Google form by April 30, 2022.
The conditions are straightforward with all projects required to use RT-Thread IoT OS operating system on the WCH CH32V307 RISC-V MCU, and the documentation and source code must be made public. So no Arduino, no FreeRTOS, etc… project., only RT-Thread. The people who select the chips over the development board are expected to design their own board with EasyEDA or their preferred EDA tool.
As I understand it, the RISC-V design challenge is open globally. Now besides the free hardware, there will also be cash prizes from $100 to $1000 distributed to 11 participants who designed the best projects. What the FAQ does not clarify is the deadline for the projects and prize selection.
As a side note, if you are interested in RT-Thread IoT OS open-source real-time operating system, there’s an upcoming “Embedded GUI Webinar” taking place on March 15 that will explain how to develop user interfaces with the OS and LVGL library. I’m also told a separate contest will be launched but no details are available at this time. Finally, the 2022 RT-Thread IoT OS Global Tech Conference is scheduled to take place on June 1-2, and (free) registration is already open.

So far working with ESP family. Interested to design one of project using this family. Already have backup of PCB and RTOS software. Over 25 years of experience in embedded domain.
Do I identify the chip on the top correctly as CH340 or something like that? Does it mean no real USB2 and programming via UART?
It is “controllable” through ethernet, but is it programmable through ethernet immediately? If it is only programmable through CH340, I would ignore it.
It is ch549 with wch-link fw
There is not datasheet/reference manual for this ic in english 🙁

It’s fairly well-documented as noted in the previous article: https://www.cnx-software.com/2022/01/21/wch-ch32v307-risc-v-development-board-features-8-uart-ports-controlled-over-ethernet/
