To participate, please fill out the form via the following link before April 30th, UTC/GMT+8:


In this contest, every project should be deployed with open-source RT-Thread IoT OS.

The project needs to deploy on WCH RISC-V MCU CH32V307, the participants will be awarded the free Hardware (chips or development boards).

The code and documentation related to your projects should be public and open source.


Open Source RT-Thread IoT OS! What’s about it?

RT-Thread is an open-source embedded real-time operating system, with its rich middle-tier components and extensive hardware and software ecosystem delivering robust support for the Internet of Things (IoT) industry. Since its inception in 2006, RT-Thread has powered 1 billion devices, which includes applications for wearable devices, smart home appliances, energy, automotive electronics, medical electronics, consumer electronics, and many other industries.

Free Hardware! What is the CH32V307?
CH32V307 is an interconnected microcontroller, based on a 32-bit RISC-V core, with a hardware stack area and fast interrupt entry. Compared with standard RISC-V, the interrupt response speed is greatly improved. With single-precision float point instruction sets added and stack area extended, the CH32V307 has higher performance, the number of U(S)ART is extended to 8,

and the number of the motor timer is extended to 4. The CH32V307 provides USB2.0 high-speed interface (480Mbps) and has a built-in PHY transceiver. Ethernet MAC is upgraded to Gbps

and integrates a 10M PHY module.

Chips and boards are all ordered and shipped from LCSC. If the contestants use chips to design, they can use EasyEDA for schematic and layout design, and EasyEDA will provide free PCB processing and PCBA.
