Pironman review – A Raspberry Pi 4 enclosure with M.2 SATA, safe power off, RGB LED strip, and more

SunFounder Pironman is a Raspberry Pi 4 enclosure inspired by Michael Klement’s DIY Raspberry Pi 4 mini server with an OLED display and ICE Tower cooling solution, as well as some improvements such as an aluminum alloy and acrylic enclosure, support for an M.2 SATA SSD, a power button for safe shutdown, an IR receiver, and an RGB LED strip. The company sent me a Pironman kit without Raspberry Pi 4 for review. I’ll check the package content, go through the assembly, software installation, and testing of the unique features listed above. Pironman unboxing Some of the main specifications are listed on the side of the package. The enclosure comes fully disassembled with the Pironman board, metal and acrylic panels, RGB LED strip, OLED display, heatsink, fan, adapters, flat cables, screws, standoffs, and so on. The top of the Pironman board (JMS580-V1.8) comes with a JMicron JMS580 USB 3.2 Gen […]

A first look at GL.iNet GL-S200 Thread Border Router kit with three nRF52840 Thread boards

GL-S200 Thread Border Router review with Thread Dev Boards

GL.iNet are better known for their routers, but the company is also offering IoT gateways and Smart Home hubs such as the GL-S10 BLE to MQTT IoT gateway. The company is now preparing to launch the GL.iNet GL-S200 Thread Border Router in early April, and I’ve been asked to do some beta testing before launch, so GL.iNet have sent me a kit with the GL-S200 and three Thread development boards acting as IoT nodes. A Thread Border Router acts as a WiFi or/and Ethernet gateway connecting to battery-powered Thread sensor nodes equipped with a low-power 802.15.4 radio. In this first post, I’ll go through the hardware and specifications, before reporting my finding in a separate post next week. GL-200 Thread Border Router kit unboxing and specifications The development boards are all identical and they were each kept in an antistatic bag. But let’s open the GL-S200 package first. The Thread […]

SONOFF MINIR4 review – A Tiny WiFi Smart Switch tested with eWelink app/web, and R5 controller

In this post, we’ll review the SONOFF Mini Extreme, also known as MINIR4, WiFi smart switch based on ESP32 wireless MCU by installing it into a wall-mounted light switch box and controlling it with both the eWelink mobile app for Android and the SONOFF R5 scene controller. SONOFF MINIR4 Installation We’ve already gone through the specifications, unboxing, and teardown in the announcement, so I’ll get straight to the installation part. Note this review was done with a light switch “box” (about 11x6cm) in Thailand, so your mileage may vary. The first challenge is that contrary to the similarly-sized SONOFF ZBMINI Extreme Zigbee switch, the MINIR4 WiFi switch requires a neutral cable, and most lights in Thailand are wired without a neutral wire, so I had to get the neutral wire from the outlet switch box underneath. When I call those “boxes” there are really holes in the wall here… Wiring […]

Renesas introduces 100 MHz RA4E2 and 200 MHz RA6E2 Arm Cortex-M33 MCUs for wearables, sensors, appliances

Renesas Electronics has added two new groups to its 32-bit RA family of microcontrollers (MCUs) with the 100 MHz RA4E2 and 200 MHz RA6E2 Arm Cortex-M33 microcontrollers designed for “high-performance applications” in small packages such as sensing, gaming, wearables, and appliances. The new microcontrollers are equipped with 40 KB SRAM, 128 KB or 256 KB flash, and integrate various on-chip interfaces such as CAN FD, USB, QSPI, SSI, and I3C interfaces to offer an easy upgrade path for products based on other members of the Renesas RA Family. Renesas RA4E2 MCU group Both the RA4E2 and the RA6E2 are the most cost-effective microcontroller groups of the RA family with integrated CAN FD, with the RA4E2 group especially well-suited to cost-sensitive applications and other systems requiring relatively high performance, low power consumption, and/or small package size. RA4E2 key features: CPU – Arm Cortex-M33 core with TrustZone @ up to 100 MHz […]
