Riotee batteryless stackable IoT board embeds an nRF52833 module (Crowdfunding)

Batteryless Riotee IoT board

Nessie Circuits’ Riotee board features a Riotee module based on Nordic nRF52833 WiSoC with a 2.4 GHz radio that targets batteryless IoT applications thanks to a stackable design taking a capacitors add-on board and a solar panel. Batteries introduce maintenance costs and environmental issues with millions of batteries disposed of every day. That’s why companies are trying to provide solutions for batteryless IoT designs such as the Everactive batteryless IoT devkit or Telink energy harvesting wireless module for remote controls. The Riotee module, board, and ecosystem also aim to play their part in reducing the use of batteries in wireless IoT devices. Riotee board specifications: Riotee module Wireless MCU – Nordic nRF52833 Arm Cortex-M4F microcontroller @ 64 MHz with 512 kB flash, 128 kB RAM, 2.4 GHz radio Memory – 128 kB of non-volatile memory (MSP430FR5962 FRAM) for “automatic checkpointing of application state” Castellated holes with 11x GPIOs including two […]

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 […]
