HT2sO

CH32V307 core board

Overview

1. The pinout and PCB layout of the CH32V307VCT6 are fully compatible with the STM32F103VCT6. 2. The MCU clock speed is 144MHz; Flash memory is 256KB; RAM is 64KB. 3. The basic program download method for the CH32 is exactly the same as that for STM32; serial port download uses PA9 and PA10; SWD download uses PA13 and PA14 (the CH32 uses a WCH-Link programmer). 4. The CH32's two USB ports also support downloading (PA11, PA12; PB6, PB7). 5. The CH32V307VCT6 integrates an Ethernet PHY, which can be directly connected to an external network adapter (e.g., HR911105A), providing complete API functions for TCP, UDP, DHCP, DNS, etc.
