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