An IoT board with many possibilities

The reel board is a low-power evaluation board based on the Nordic Semiconductor nRF52840 SoC. The board has a built-in debug adapter that is based on the firmware of the DAPLink interface. It is equipped with an electrophoretic display (EPD), environmental sensors (temperature, humidity, light, accelerometer) and a Bluetooth interface, which is why it is particularly suitable for the following applications:

  • Battery operated sensor node
  • Energy-saving, cost-effective HMI for remote control and monitoring of environmental sensors
  • Temperature and humidity monitor 
  • Product, name or price tag
  • Interactive badge for meetings and conferences

Zephyr ™

The Zephyr OS has been hosted by the Linux Foundation since 2016 and offers practical, ready-made software components for easier development with the reel board. The following SW components can be implemented more quickly in your product with the Zephyr real-time BSP:

  • device drivers
  • (Network) protocol collection
  • Over the Air (OTA) updates

link board BASE

With the link board BASE, further link boards or 3rd party shields in Arduino UNO R3 format can be connected to the reel board. It also has a NOTM.2 connector and a more powerful DCDC converter than the reel board.

The link board BASE can be used in two ways:

As an adapter
The reel board is plugged into the link board BASE. Interfaces and shields on the reelboard can be used as long as there is no conflict between I²C components. Care should be taken to ensure that the entire circuit is adequately powered.

or stand-alone
The NOTM.2 adapter is removed from the reel board and connected to the NOTM.2 connector of the link board BASE. The connection to the shield connector is identical to the configuration above, no software adjustments are required. The stand-alone configuration is suitable for applications in which interfaces on the reel board are not used or are in conflict, the performance of the reel board is insufficient or for prototypes in the field.
