RT-Thread Vision board review – Part 1: OpenMV on Renesas RA8D1 Cortex-M85 microcontroller

I am always interested in real-time operating systems (RTOS) for microcontrollers (MCUs) with my past backgrounds in µC/OS-II, mbed, and FreeRTOS. When the opportunity arose to get my hands on the RT-Thread Vision Board, thanks to the RT-Thread team and CNX Software, I was excited to check it out. This board, a collaboration between RT-Thread and Renesas, packs a powerful Renesas RA8D1 Cortex-M85 MCU and comes pre-loaded with OpenMV firmware. OpenMV’s MicroPython engine lets you jump right into embedded vision development, perfect for experimenting with computer vision tasks. But the real power lies in RT-Thread’s ability to handle tasks very quickly, which we’ll explore with C/C++ development in part two. This first part will focus on getting you familiar with the hardware using the OpenMV firmware, making it a smooth entry point for beginners. Plus, I have a collection of other Renesas evaluation boards, so you can bet I’ll be […]

The RPGA Feather dev board pairs RP2040 chip with a Lattice iCE40 FPGA for sensor fusion projects

Oak Development Technologies’ RPGA Feather board integrates the Raspberry Pi RP2040 microcontroller with the iCE5LP4K FPGA from Lattice Semiconductor into a compact development board in the Adafruit Feather form factor. The iCE5LP4K FPGA is an ultra-low-power chip in the iCE40 Ultra product family designed for mobile applications such as smartphones, tablets, and handhelds, while the Raspberry Pi RP2040 microcontroller makes it much easier to program the FPGA using CircuitPython. We have seen Oak Development Technologies’ earlier forays into FPGA Feather-compatible products such as the IcyBlue board (also based on iCE5LP4K FPGA) and the Lattice FeatherWing. RPGA Feather specifications: MCU – Raspberry Pi RP2040 dual-core Cortex-M0+ microcontroller @ 133 MHz with 264KB SRAM FPGA – Lattice Semiconductor iCE5LP4K FPGA Logic Cells – 3,520 logic cells Memory 80 Kbits of embedded Block RAM (EBR) Distributed RAM: 640 bits 2x hardware I2C blocks and 2x hardware SPI blocks 26 I/Os for customized interfaces […]

$20 Zigbee & Z-Wave mPCIe module targets Home Assistant gateways

Mixtile’s “2-in-1 Zigbee & Z-Wave mPCIe module” is a relatively inexpensive way to add Zigbee and Z-Wave connectivity to a Home Assistant server without having USB dongles sticking out of the server and taking some of its spare USB ports. The module is compatible with any computer, gateway, or SBC with a spare mini PCIe socket featuring a USB 2.0 interface such as Rockchip RK3568-powered Mixtile Edge 2 Kit gateway. You’ll also need some way of mounting the antennas after connecting them to the IPEX-1 antenna connectors on the module, the Edge 2 Kit comes with multiple antenna holes. Mixtile 2-in-1 Zigbee & Z-Wave mPCIe module specifications: Wireless MCUs Silabs EFR32MG24 Arm Cortex-M33 @ 78.0 MHz with 256 kB RAM, 1536 kB flash Radio Frequency – 2.4 GHz (802.15.4 radio) TX Power – up to +19.5 dBm RX sensitivity – -105.4 dBm at 250 kbps Protocols – Zigbee, Matter, Thread […]

NiCE5340 SoM packs Nordic nRF5340 MCU, Lattice iCE40 FPGA, and 11 sensors into a tiny 29x16mm form factor

Stefano Viola’s NiCE5340 SoM is built around a Nordic Semi nRF5340 Bluetooth SoC, an iCE40 FPGA, 11 sensors, a battery charger, and various other peripherals in a 29×16 mm form factor. The nRF5340 used in the SoM is a low-power, dual-core Arm Cortex-M33 SoC with Bluetooth 5.4, Bluetooth LE (BLE), Thread, Zigbee, and other proprietary protocols. Meanwhile, the Lattice iCE40 FPGA features 3520 logic cells, 80 Kbits of embedded Block RAM, I2C, and SPI blocks, and many other features that make it suitable for applications like environmental monitoring, health tracking, and others. Previously, we have written about Unexpected Maker NANOS3, TinyS3, FeatherS3, and ProS3 boards, and ESP32-S3 4G dev board which all fall under the tiny and compact board category but this is the first time we have seen an MCU board with so many features built into a module of that size. Stefano Viola’s NiCE5340 SoM Specification ICs Nordic […]
