IoTextra modular automation boards with 4 inputs, 4 outputs work with Raspberry Pi and ESP32 MCU boards

IoTsmart IoTextra modular automation boards

Last week, we wrote about the Olimex PICO-EVB automation board equipped with four relays and four isolated inputs and designed for Raspberry Pi Pico-compatible boards. Make Things Happy does something similar, but in a modular way, with the IoTextra family of carrier boards with four inputs and four outputs for automation, and supporting a range of IoTsmart MCU boards based on Raspberry Pi RP2350, ESP32-S3, etc… There are currently six IoTextra boards shipping or in development, all measuring 56×47 mm and featuring 3750 Vrms galvanic isolation per channel. All IoTextra modules support different MCU platforms via horizontally or vertically mounted IoTsmart SoM carriers based on Waveshare RP2350 and ESP32-S3 modules, Seeed Studio XIAO boards, and others, all connected via the HOST connector. All IoTextra 8-channel modules support several software ecosystems out of the box: IoTflow framework for no-code programming of distributed MCU nodes over MQTT and Node-RED; used to build custom […]

Silex SX-SDMAX6E tri-band Wi-Fi 6E + Bluetooth LE module features NXP IW623 SoC, comes in M.2 or LGA package

Silex SX SDMAX6E tri band Wi Fi 6E + Bluetooth LE module LGA(Right) M.2(Left)

Back in August last year, we wrote about NXP’s IW623 tri-band (2.4GHz, 5GHz, 6GHz) Wi-Fi 6E and Bluetooth LE Audio SoC, but at the time, there was no ready-to-use module based on it. Now, NXP has partnered with Silex Technology to launch the SX-SDMAX6E module, available in a surface-mount LGA package or an M.2 2230 Key-E card. The module supports Bluetooth 5.x connectivity via UART and Wi-Fi via SDIO. It operates from a 3.3V supply with 1.8V support on the LGA version. It has an industrial operating temperature range of -40°C to +85°C and is designed for both high-throughput applications, such as video streaming, and low-power, battery-operated devices in harsh environments. It also supports various antenna options, fast roaming, and long-term lifecycle backing through Silex and NXP. Silex SX-SDMAX6E specifications: Wireless chipset – NXP IW623 tri-band SoC Connectivity Wi-Fi Tri-band Wi-Fi 6E (2.4 GHz, 5 GHz, 6 GHz) IEEE 802.11a/b/g/n/ac/ax […]

Maxell PSB2032 35 mAh all-solid-state coin cell battery targets industrial IoT devices

Maxell PSB2032 35 mAh all-solid-state coin cell battery for IoT devices

Maxell PSB2032 is a rechargeable “all-solid-state” coin cell battery for industrial IoT devices, which more than quadruples the capacity of the earlier PSB401010H ceramic-packaged solid-state battery, increasing it from 8mAh to 35mAh. As its name implies, it measures 20 mm in diameter and 3.2 mm in height, and delivers key benefits of solid-state batteries such as a wide discharge temperature range, high reliability, and high safety. It’s also easier to install than ceramic-packaged batteries requiring reflow soldering, since it comes pre-equipped with two connection terminals suitable for mounting into small-sized devices. The company shared a comparison table between its two solid-state batteries. For reference, the capacity of a typical CR2032 battery is 220–240 mAh, so the PSB2032 has a much lower capacity. However, it can be recharged and works in demanding environments with a wide temperature range and high safety requirements. The last time we wrote about solid-state batteries was […]
