ZBMINI Extreme Zigbee smart switch review with Home Assistant

Sonoff ZBMINI Extreme Review Home Assistant

SONOFF has rolled out smart switches in the market for years, and for each iteration, they make their devices smaller and more capable. The latest ZBMINI Extreme Zigbee Smart Switch or ZBMINIL2 or ZBMINI Extreme for shorts is what we will review today. Take note that there are both Zigbee and Wifi versions that come with the same form factor, we will walk through the Zigbee version first and we will review the WiFi version – SONOFF MINI Extreme (MINIR4) – later on. The ZBMINI Extreme is designed to work without a Neutral (N) line. Those who have difficulty wiring the N line to the switch will definitely love this. In many locations, the Neutral (N) line is not wired and would require a lot of work and expenses for cabling. SONOFF ZBMINI Extreme eases that challenge since there’s no need for the Neutral wire at all. This review will […]

SONOFF MINI Extreme (MINIR4) ESP32 WiFi smart switch can fit into most gang boxes

SONOFF MINI Extreme

SONOFF MINI Extreme (aka MINIR4) is a ridiculously small WiFi smart switch based on ESP32 wireless microcontroller and designed to be connected to a load such as a light bulb and a wall switch that can be a momentary switch, a door exit switch, an SPDT switch, a latching switch, or even dry contact sensors. The tiny form factor (39.5×33 x16.8mm) enables the WiFi smart switch to fit into various boxes, even the smaller European gang boxes. Just like other SONOFF home automation devices, the MINIR4 works with eWelink mobile app, but it also implements some new interesting features such as the ‘Detach Relay’ mode. SONOFF MINI Extreme (MINIR4) specifications: MCU – Espressif Systems ESP32 dual-core wireless microcontroller Connectivity 2.4 GHz WiFi 4 Bluetooth LE used for pairing Input – 100-240V ~ 50/60Hz 10A Max Output – 100-240V ~ 50/60Hz 10A Max (resistive load) Dimensions – 39.5 x 33 x […]

STMicro adds more STM32U5 Cortex-M33 MCUs with NeoChrom 2.5D GPU, 128KB to 4MB flash, NIST certification, etc…

STM32U5 MCU family 2023

STMicro has added three new families to its STM32U5 Cortex-M33 microcontroller series with the entry-level STM32U535/545 with as little as 128KB flash, the STM32U595/5A5 with up to 4MB of Flash and 2,514KB of RAM, and the STM32U599/5A9 with similar features as the STM32U595/5A5 by adding the new NeoChrom 2.5D GPU plus TFT-LCD and DSI display interfaces. STMicro also announced that STM32U5 series MCUs were the first general-purpose MCUs to receive NIST-embedded random-number entropy source certification. As of now, along with the STM32U575/585 introduced in February 2021 with an optional Chrom-ART 2D GPU, STMicro offers eight product lines as part of the STM32U5 MCU series as shown in the table below. That means the STM32U5 microcontroller can address a wider range of applications with the STM32U535/545 targetting lower-cost applications with less flash and RAM, the “legacy” STM32U575/U585 for mid-range applications, and the STM32U59X/5AX for applications where more storage and memory is […]
