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

ESP32-C3 board 25 RGB LEDs

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 […]

Horizon X3 AI development board is powered by Sunrise 3 AI Edge Arm processor

Horizon X3 AI development board

Horizon X3 AI development board is powered by Horizon Robotics Sunrise 3 (aka X3) quad-core Cortex-A53 processor with a 5 TOPS NPU, and multiple camera support with the chip apparently designed for the automotive industry. [Update January 25, 2022: A third-party company, Finsbury Glover Hering, claiming to represent Horizon Robotics informed CNX Software the chip is not designed for the automotive market, and that Horizon’s AIoT business is actually limited to the domestic China market and not overseas.] The devkit is comprised of a Sunrise 3 system-on-module with 1GB LPDDR4 & 16GB EMMC memory, as well as a baseboard with Gigabit Ethernet and WiFi, HDMI up to 1080p60 and MIPI DSI interface, a camera interface, and a 40-pin header for expansion.

Indoor positioning BU01 development board can detect tiny body movements (Sponsored)

Ai Thinker BU01 development board

GPS is available for outdoor positioning, what about indoors? There is a positioning technology that is more accurate than GPS: UWB. The technology offers positioning accuracy within 10cm which greatly compensates for the shortcomings of the indoor RSSI positioning of past IoT products. UWB technology is a wireless carrier communication technology that uses a frequency bandwidth above 1 GHz. It does not use a sinusoidal carrier but uses nanosecond-level non-sinusoidal narrow pulses to transmit data and occupies a large frequency spectrum, hence the name “Ultra-Wideband”, or UWB for shorts. Besides positioning, UWB can also be used for data transmission with a rate of hundreds of megabits per second. BU01 development board features MCU – STMicro STM32F103 Arm Cortex-M3 microcontroller UWB module – Ai-Thinker BU01 module 50 I/O pins exposed for functions. Sensors – Onboard acceleration sensor, temperature, and humidity sensor Misc – User buttons and LED Power Supply – 5V […]

Sipeed Lichee RV RISC-V module gets $5+ carrier board with HDMI and USB ports, optional WiFi

Sipeed Lichee RV Starter Kit

Sipeed introduced the Lichee RV Allwinner D1 Linux RISC-V board going for just $17 with 512MB RAM last month. While with a USB-C port it could be used as a standalone part, its dual M.2 connector makes it more like a module and we noted a tiny carrier board was in the works at the time. The baseboard is now available and known as the Lichee RV Dock adding HDMI and USB ports, as well as a 40-pin GPIO header for just $5, or $8 if you’d like to get Wi-Fi 4 and Bluetooth 4.2 connectivity through a Realtek RTL8723DS module. Sipeed Lichee RV Dock specifications: Supported system-on-module (SoM) – Lichee RV module with Allwinner D1 RISC-V processor @ 1 GHz, 512MB DDR3, MicroSD card slot, and USB Type-C OTG port Storage – Optional SPI flash Display interfaces HDMI port up to 4Kp30 Optional RGB interface for up to 720p30 […]
