Recyclable PCB created by the University of Washington is made from Vitrimers

Ludwik Leibler a Polish-born French physicist and his team from the Laboratoire Matière Molle et Chimie at ESPCI ParisTech created a new class of plastics known as “vitrimers” and material researchers at the University of Washington (UW) have leveraged the new plastics to develop a recyclable PCB (printed circuit board) known as “Vitrimers PCB” (vPCB) that can be recycled many times over. The team tested their vPCB for strength and electrical properties and found that they are very similar to standard FR-4 PCB material. This means Vitrimers PCBs could offer a solution to reduce landfill waste and make it easier to recycle leftover copper, maximizing resource recovery. Key Features of Vitrimers-based Recyclable PCBs: Base material – Employs vitrimer epoxy, a type of polymer that can be repeatedly cured and uncured without damage. Environmentally sustainable – Designed to reduce e-waste and offer a more circular lifecycle for electronics. Performance – Electrical […]

Arduino Pro Opta D1608E/D1608S expansions feature electromechanical or solid-state relays, 16 I/Os

Arduino has recently announced two new expansions to their Arduino Pro Opta PLC series – the Arduino Pro Opta Ext D1608E and Arduino Pro Opta Ext D1608S, the main difference between the two is that the D1608E features 8 electromechanical relays (EMRs) whereas the D1608S features solid-state relays (SSRs). Other than that both expansion modules have 16x programmable I/Os (0-24 V digital / 0-24 V analog) which doubles the number of I/Os we have seen on the Opta micro PLC. Both are compatible with the Arduino IDE and the PLC IDE and are easy to install on a DIN rail. These features make it suitable for control, monitoring, and predictive maintenance applications. Previously we have seen Arduino launch a PLC Starter Kit for those who want to get started with PLCs. Additionally, we have written about ESP32-powered PLCs, Raspberry Pi-powered PLCs, and more. Feel free to check those out if you […]

NanoCell V2.1 battery-powered ESP32-C3 IoT board runs ESPHome for Home Assistant integration

The NanoCell V2.1 is a development board built around the Espressif ESP32-C3 SoC (system-on-a-chip) preloaded with ESPHome firmware for low-power applications and improved Lithium battery management. The development board is a white printed circuit board with gold-plated contacts and a battery fuel-gauge IC, designed by Frapais’ lab in Greece. As the name suggests, the NanoCell V2.1 is the latest in a series of iterations of ESP32-C3-based devices targeted at low-power applications. Compared to earlier versions, it offers a better user experience and improved power efficiency. It features a buck-boost converter that reduces standby current consumption to 66uA (excluding the current consumed by the ESP32 module). The battery management system (BMS) integrated circuit supports accurate capacity measurement and protects connected Lithium batteries from overcharging and other harmful scenarios. Also, two LEDs on the board serve as power and charging indicators to relay the board’s status. It is based on the same […]

Loongson 2K1000LA dual-core LoongArch processor powers industrial SBCs and IoT gateways

Banana Pi BPI-5202 Loongson 2K1000LA SBC

Loongson 2K1000LA is a 1GHz dual-core 64-bit LoongArch processor designed for industrial applications with gigabit Ethernet, SATA, two PCIe interfaces, two digital video outputs, audio interfaces, USB 2.0, and others all in a 1 to 5W power envelop. It is found in Loongson’s own development board and Banana Pi BPI-5020 2K1000LA SBC. The LoongArch architecture was first introduced in 2021 as an alternative to Arm, x86, and RISC-V, and heavily inspired by MIPS with extra instructions. Some of the first LoongArch processors were the Loongson 3A5000 and 3C5000 SoCs for desktop computers and servers respectively, and now, the company has launched a lower-power processor for industrial applications, such as IoT gateways, with the 2K1000LA. Loongson 2K1000LA specifications We only have some basic specifications from the product page on Loongson’s website.; CPU – 2x 64-bit LoongArch cores clocked at 1GHz FPU – 128-bit vector unit Cache 32KB L1 instruction cache 32KB […]

Alfa Networks AHST7394S Wi-Fi HaLow module enables low-power, long-range IoT connectivity up to 1km

Taiwanese wireless equipment manufacturer, Alfa Networks, and US-based Wi-Fi HaLow semiconductor company, Newracom, have collaborated to develop the AHST7394S Wi-Fi HaLow module. The solder-down module is based on Newracom’s NRC7394 SoC, a low-cost and high-efficiency HaLow SoC chipset providing up to 17dbm output power and capable of connecting to a maximum of 8K devices within a single network. The NRC7394 also supports a standalone mode, which enables the execution of a wide range of IoT applications on the embedded ARM Cortex-M3 CPU. While HaLow is more energy-efficient than other Wi-Fi types, low-power operation modes such as legacy, TWT, and WMM-PS can reduce power consumption further. The AHST7394S Wi-Fi HaLow module supports a data rate of up to 15Mbps, over 600 times faster than LoRaWAN while maintaining a good range (over 1km). The second-generation HaLow module is perfect for building long-range, ultra-low-power networks in sub-1 GHz, license-exempt frequency bands. It is a […]
