LimeNET Micro 2.0 Developer Edition board leverages Raspberry Pi CM4 and LimeSDR XTRX SDR module (Crowdfunding)

The LimeNET Micro 2.0 Developer Edition board is a modular software-defined radio (SDR) platform from Lime Microsystems that is based on the Raspberry Pi Compute Module 4 and the company’s own SDR board, the LimeSDR XTRX. It builds upon previous versions from Lime Microsystems, such as the LimeSDR Mini and LimeSDR Mini 2.0. It features a MIMO (multiple-input, multiple-output) radio and runs the more powerful Compute Module 4, an upgrade from the Raspberry Pi CM3 in earlier versions. The LimeSDR XTRX is an open-source, high-performance SDR in a compact, Mini PCIe form factor.  It provides a platform for building logic-intensive digital and RF designs and can be used for MIMO antenna configurations from 2Tx2R to 32Tx32R. The platform is built around a planar system board, the LimePSB RPCM, which integrates the CM4, the XTRX, and other components and interfaces to make a complete baseband + RF solution for diverse wireless […]

Serial Bus Servo Driver HAT (A) can drive up to 253 servos simultaneously

Waveshare has recently introduced the Serial Bus Servo Driver HAT (A) ESP32-powered servo motor controller for the Raspberry Pi designed to drive up to 253 serial servos simultaneously. The servos can be controlled via UART or USB through the Pi SBC or used as a standalone controller for a robotics project. The board has a wide input voltage range of 9 to 25 volts and features an onboard XT60 connector, a screw terminal, and a DC barrel jack any of which can be used as power input. Besides that, the board features an RS485 port a TTL Servo header, and a UART control switch for convenience. Previously we have written about the Suptronics X200 HAT multifunction expansion board for the Pi with servo support, as well as the ELECFREAKS Wukong 2040 which can also be used to drive servos.

Apple’s Embedded Swift programming language supports ESP32-C6, Raspberry Pi RP2040, STM32F7, nRF52840 microcontrollers

Apple has released a beta version of Embedded Swift that notably works with Espressif ESP32-C6 wireless RISC-V microcontroller, and the company also built a Matter sample based on ESP-IDF and ESP-Matter SDKs. Embedded Swift is not limited to the ESP32-C6 and supports other microcontrollers from STMicro, Raspberry Pi, Nordic Semi, etc… Apple Swift programming language is mostly designed for mobile app development, but we’ve also seen it being used on Mad Machine’s SwiftIO board powered by a 600 MHz NXP i.MX RT1052 Arm Cortex-M7 crossover processor and the tiny SwiftIO Micro launched a few years later. The company has now decided to create a subset of the Swift programming language better suited to microcontrollers simply called Embedded Swift that’s currently working on STMicro STM32F746, Raspberry Pi Pico, nRF52840, and ESP32-C6. The “Go small with Embedded Swift” presentation at WWDC 2024 shows how to get started with Embedded Swift using Espressif […]

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 […]

LattePanda Mu review – Part 1: an Intel N100 Compute Module tested with Windows 11, carrier boards with PCIe slots

Last April, DFRobot launched the LattePanda Mu x86 Compute Module powered by an Intel N100 Alder-Lake processor with 8GB RAM and a 64GB eMMC flash along with Lite and Full function carrier boards for evaluation. End customers will typically design their own carrier board without having to take of high-speed signals for the LPDDR5 memory and other complexities during the PCB layout. DFRobot has sent us the LattePanda Mu module for review along with the Lite and Full Function carrier boards, a heatsink for passive cooling, and an active cooler so we can compare both cooling solutions.  Let’s have a look at the LattePanda Mu module and accessories before testing the kit with the Windows 11 operating system, including the PCIe x4 slot. LattePanda Mu kit unboxing The parcel included three retail boxes. The smallest box housed the LattePanda Mu Compute Module, a heatsink, and an active cooler. The second […]
