Rakwireless has launched several IoT evaluation boards such as RAK4260 LoRaWAN EVB relying on WisBlock modules comprised of a carrier board and a module. So far, those were always sold as part of evaluation boards, but now the company is trying to expand WisBlock use as a modular system, so users can easily build their custom systems, LEGO style.
The modular system is based on four different block types:
- WisBlock Base – A carrier board with connectors for other block types, power supply, some ports
- WisBlock Core – Module with a microcontroller/processor
- WisBlock Sensor – Modules with environmental sensors, motion sensors, ambient light sensors, or others
- WisBlock IO – Adds more inputs, outputs, or connectivity options including LTE-M / NB-IoT, cellular and Wi-Fi modules, NFC reader, and interfaces for I2C, UART, ADC, and GPIO.
The fist WisBlock Core will combine a Nordic nRF52840 and a Semtech SX1262 LoRa transceiver, and be programmable via the Arduino IDE or PlatformIO. The company will also offer six different sensor modules and eight IO extension boards.
Rakwireless prepared a Github repository with a Quick Start Tutorial and several examples to create various solutions such as a BLE gateway, a GPS tracker, an environmental monitoring station, etc… WisBlock IoT modular system is not only design for prototyping and development, but the company aims to make it a production-ready solution.
WisBlock IoT modular system kit is now available right now, but the company has launched a beta testing program, where interested developers can apply to request a free kit. Selected developers should then receive their kit sometime in October 2020.
