CH32V307V-EVT-R1
The CH32V307V-EVT-R1 is a development board for the CH32V307 RISC-V MCU.
As a development board, this one is clearly inspired by ST's Nucleo boards as it includes an Arduino header as well as a built-in flash/debug tool (they call it WCH-Link also inspired by ST-Link).
I never really understood why they (both this one and ST) choose to include an Arduino header. As far as I know, most - if not all - Arduino boards are running at 5V, which makes them possibly incompatible with the 3.3V used on boards such as this.
The CH32V307V-EVT-R1 board itself is readily availble from LCSC at around $12 (+ shipping).
Hardware Description
It is worth noticing that contrary to various ST development boards, the two user LED's and the user button are by default only wired to the header, not the MCU itself. This means that a jumper lead is necessary to use any of these.
