Arduino UNO R4 Renesas RA4M1 32-bit maker board offered with optional ESP32-S3 WiFI & BLE module

Arduino UNO R4 board

Arduino have launched an upgrade to their 8-bit Arduino UNO R3 board with the Arduino UNO R4 featuring a 48 MHz Renesas RA4M1 Arm Cortex-M4F 32-bit microcontroller, and an optional ESP32-S3 module for WiFi 4 and Bluetooth 5.0 connectivity. The new Arduino UNO R4 offered improved performance and greater resources since the MCU is clocked three times faster than the 8bit AVR MCU found in the UNO R3, the board gets sixteen times more RAM (32KB vs 2KB to 32kB) and eight times more flash memory (256KB vs 32kB). The USB Type-B device port has been upgraded to a more modern USB Type-C port and the UNO R4 can take up to 24V supply voltage. Arduino UNO R4 (preliminary) specifications: Microcontroller – Renesas RA4M1 Arm Cortex-M4F MCU @ 48 MHz with 32KB SRAM, 256KB flash. 8KB dataflash Wireless (Arduino UNO R4 WiFi only) – ESP32-S3-MINI-1 module based on ESP32-S3 dual-core […]

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

SONOFF MINIR4 wiring

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 […]
