reel board is an evaluation board based on the Nordic Semiconductor nRF52840 SoC with an integrated 2.4 GHz transceiver supporting Bluetooth Low Energy and IEEE 802.15.4. The board was developed by PHYTEC in cooperation with Zephyr Project for the "connect-up" Hackathon during Embedded Linux Conference (ELC) and OpenIoT Summit Europe on October 22-24, 2018.
The board has a built-in debug adapter based on the DAPLink interface firmware and NXP MK20DX128VFM5 SoC. It is optimized for low power applications and supports two power source configurations, battery and micro USB connector.
It is equipped with the Electrophoretic (electronic ink) Display (EPD), environmental (temperature, humidity, light, accelerometer) sensors, and Bluetooth connectivity making it easy to experiment and evaluate the Zephyr OS in these kinds of use cases:
- battery powered sensor node
- low-power, low-cost human-machine interface (HMI)
- for remote control and environmental sensor monitoring
- temperature and humidity monitor on your table
- product, name or price tag
- interactive badge for meetings and conferences
Hardware
On the front of the board are RGB-LED, ADPS9960 and HDC1010 sensors, and Electrophoretic Display. The RGB-LED is controlled by the nRF52840 via GPIO pins. Display is controlled by the nRF52840 via SPI and 3 GPIOs.
On the back side of the board are all other components such as nRF52840, circuit for the Debug Adapter, On/Off and power source switch, battery holder, buttons and MMA8652 (accelerometer) sensor.
ADPS9960 is Digital Proximity, Ambient Light, RGB and Gesture sensor. HDC1010 is a digital humidity and temperature sensor. MMA8652 is a 12-bit Digital Accelerometer. All sensors are connected to the I2C bus and one GPIO pin each, which can be used as an interrupt source.
