BentoIO CMX1 – A low-profile Raspberry Pi CM5 carrier board that’s just 11mm thick

The BentoIO CMX1 is a compact, low-profile Raspberry Pi CM5 carrier board, developed by Terioto in Germany. With an 85 x 85 mm footprint and a height of just 11 mm, it’s designed for space-constrained applications like embedded systems, industrial control, and compact edge devices. After the official launch of the Raspberry Pi CM5 module and its carrier board, we’ve seen boards like Waveshare CM5-NANO-B and Orange Pi CM5 “Tablet” Base Board get released. There is no doubt that they are compact, but they are not as slim as this board. While it’s slim, that doesn’t mean it lacks I/Os; it includes a 40-pin Raspberry Pi-compatible GPIO header, two USB 3.0 ports, two internal USB 2.0 headers, a MIPI DSI connector and an optional HDMI port for video output, optional gigabit Ethernet, a PCIe M.2 M-Key for expansion, and it uses a USB-C for power. Other features include an RTC battery connector, […]

LUNYEE 3018 Pro Ultra Review – Part 1: Unboxing and assembly of the CNC Router with a 500W spindle

LUNYEE has just sent us a 3018 Pro Ultra CNC router for review. The CNC machine is an update to the 3018 Pro Max with improved performance and precision, as well as wider material support. It features a 500W spindle motor with a maximum speed of 5000mm/min, a full aluminum alloy structure, and an HGH15 linear guide X-axis that allows for reliable milling of hard materials such as aluminum, copper, and brass. Its 3-axis lead screw drive system provides smooth movement with an accuracy of ±0.1mm. The machine comes partially pre-assembled and should only take a short time to assemble. Safety features include an emergency stop switch and limit switches on every axis. It’s compatible with popular GRBL-compatible software such as Fusion360, Easel, Candle, UGS, LaserGRBL, LightBurn, and so on, and can be used for milling wood, acrylic, carbon fiber, and there’s also an option for installing a laser module, […]

MicroSui lightweight, open-source C framework brings the Sui Network to microcontrollers

MicroSui (Sui Embedded Framework) is a lightweight, modular, open-source C framework that brings the Sui Network to microcontrollers from low-end 8-bit MCUs like AVR to more powerful 32-bit SoCs like the ESP32. Wait… What’s the Sui Network / Protocol exactly? It’s a blockchain platform designed for high-speed, scalable, and low-cost decentralized applications, which was introduced in May 2023 by Mysten Labs, a company founded by former Meta engineers. It competes with networks like Solana and Ethereum but with better performance. So far, the Sui Network works with web and mobile applications, but MicroSui aims to expand its usage to resource-constrained embedded devices. We’re told MicroSui provides support for all core operations such as key management, transaction construction, signing, and broadcast. It is a pure-C library with no OS dependency or dynamic memory usage, so it can be deployed on a wide range of microcontrollers. Higher-end microcontrollers with Internet access, such […]
