WCH CH32V307 RISC-V development board features 8 UART ports controlled over Ethernet

CH32V307 RISC-V development board 8x UART

CH32V307V-EVT-R1 is a development board based on WCH CH32V307 RISC-V microcontroller with an Ethernet port, an USB Type-C port, and eight UART interfaces accessible through headers. As we noted in our article about CH583 Bluetooth 5.3 RISC-V microcontroller, WCH (Jiangsu Qin Heng) has started to share resources like datasheets and code samples through Github. They’ve done the same again for CH32V307 with schematics (PDF only), a datasheet in English, and firmware either bare metal or based on RT-Thread OS to control the eight serial interfaces over Ethernet. Let’s check CH32V305 and CH32V307 MCU specifications first: MCU core – WCH designed RISC-V4F 32-bit RISC-V core up to 144MHz FPU – Single-cycle multiplication and hardware division, hardware float point unit (FPU) ; Memory – Up to 64KB SRAM Storage – Up to 256KB Flash Networking – Gigabit Ethernet MAC, 10 Mbps PHY USB – 1x USB 2.0 OTG full-speed interface, 1x USB […]

Board with 25 RGB LEDs is offered with ESP32-C3 or ESP32-Pico-D4

In case you are in need of a tiny WiFI or Bluetooth-connected board with an RGB LED matrix, two have shown up on Banggood with basically the same 25 RGB LED design , except “C3FH4 RGB” board is based on ESP32-C3 RISC-V SoC, while the other, named “PICO D4 RGB“, features ESP32-Pico-D4 SiP (System-in-Package). The boards are cute and the main purpose is probably for decoration/ornament, but I’d imagine if you purchase a few they could also be used as an experimentation/education platform for mesh networking, using the ESP Mesh Development Framework (ESP-MDF) for instance. C3FH4 RGB / PICO D4 RGB board specifications: SoC/SiP C3FH4 RGB board – ESP32-C3FH4 SoC with RISC-V core @ 160 MHz, 4MB flash, 2.4GHz Wi-Fi, and Bluetooth 5 LE with Long-Range support PICO D4 RGB board – ESP32-PICO-D4 system-in-package with ESP32 dual-core Xtensa processor @ 240 MHz, 2.4GHz Wi-Fi and Bluetooth dual-mode, 4MB flash Ceramic […]
