Link.ONE LTE-M, NB-IoT, and LoRaWAN all-in-one LPWAN devkit is programmable with the Arduino IDE

RAKwireless Link.ONE is an all-in-one LPWAN development kit programmable with the Arduino IDE and based on nRF52840 Cortex-M4F 2.4 GHz multi-protocol wireless microcontroller, Semtech SX1262 LoRa RF transceiver, and Quectel BG77 LTE-M and NB-IoT module and comprised of components from the company’s WisBlock IoT prototyping platform.

Besides the WisBlock modules, the kit includes everything to get started with four antennas for LTE-IoT, LoRaWAN, GNSS, and Bluetooth connectivity, a USB cable for power and programming, and a Monogoto SIM card with global coverage and 500MB of data valid for 10 years.

Ken YU, RAKwireless CEO, told CNX Software the reason for creating the Link.ONE devkit and potential use cases:

… we discovered many developers like to use LoRa/LoRaWAN and Cellular in a single product, especially for the industrial IoT. The use case might include
Use case 1:You can set LoRaWAN as primary and Cellular NB-IoT as secondary , or you can set Cellular as primary and LoRaWAN as secondary
Use case 2: you can use Cellular as backhaul, but use LoRa as P2P to wake up devices
Use case 3:  equipping every device with cellular modem is too expensive (each device needs SIM card) so multiple sensors share one cellular modem by sending data in LoRa P2P

The documentation provides more details about the hardware, instructions to assemble the kit, and instructions to get started with the Arduino IDE and the RAKwireless BSP for the Arduino Board Manager.

RAKwireless  Link.ONE all-in-one LPWAN development kit can be purchased for as low as $56, but that’s without the Unify Enclosure, and if you’d like the IP65 enclosure, the total price for the kit is $94.

  1. I would think it’s 500 megabytes, not megabits (the included data with the SIM).

    Surprisingly affordable given all the stuff in there (the enclosure is comparatively quite expensive, on the other hand).

    1. That confused me as well, but I could see 500Mb written on all pages when I checked.

      1. Mmmmhh confusing, the product page says 500MB once and then 500Mb once. The mystery remains, I think you’ll have to ask them 🙂

  2. oooh – this looks great! I love the rakwireless products and wisblock modular system. However, having to research each component and figure out how (and if) it will all integrates has put me off until now.

    The wistrio is a game changer and this package brings it all together. Take my money 🙂

    Thanks for sharing this post.

  3. 100usd is actually quite cheap. Would’ve liked it to be a nrf5340 instead of the old (but perfectly fine) 52840
