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.

Riotee board specifications:

Most people will use the add-on boards with Riotee board starting with the optional Sensor shield with a Bosch BMA400 digital accelerometer, a Sensirion SHTC3 digital temperature and humidity sensorand Vesper VM1010 analog microphone with power switch.

You’d place it directly on top of the Riotee board, and after the Riotee Capacitor Shield on top with a range of capacitors namely three 47uF MLCCs, three 220uF MLCCs, one 10mF EDLC, and one 220mF EDLC, as well as an 8-position DIP switch to enable specific capacitors.

The stack is completed by the Riotee Solar Shield with four AnySolar KXOB25x03F solar panels and a DIP switch for selectively connecting 1, 3, or 4 panels in parallel that enable batteryless operating for the IoT board.

All hardware and software have been released on GitHub with KiCad hardware design files for the main board and all add-ons/shields, and the software is comprised of three parts:

Further documentation can also be found on the project’s website.

Nessie Circuits is currently offering the Riotee module, board, and shields on Crowd Supply crowdfunding platform. The Riotee module only requires a $55 pledge, while the Riotee board goes for $89. If you’d like the Capacitor, Solar, and/or Sensor shields, you’ll need to add $35 for each. Shipping adds $8 to the US, and $18 to the rest of the world with deliveries expected to start by the end of May 2023.
