Plug this module into any electronic product, and instantly gain full managed connectivity to your cloud instance.

This hardware module connects to your product using: UART / RS485 / GPIO / I2C interfaces.

Once connected you can configure it using our cloud DeviceTone management system to read data/send commands from/to the device.

This module also has pre-installed sensors for Temperature and Location (GPS).

You can have a working prototype in ONE DAY!, and a whole IoT system working in a few weeks.

If needed, we can quickly respond and supply a different module design according to your needs.


The module is based on the Nordic nRF52840 MCU with the Quectel BG96 modem.

There are two main deployment options for the module:

1) The module connects to existing hardware – it is usually deployed into a machine /on the side of a machine, and interfaced to it using UART / RS485 / GPIO / I2C interfaces. The machine’s PCB may have 5V power supply on it and the connected interface is 5V. It may also be 3.3V.

2) The module is autonomous – it is placed in the field, without wiring it to anything.
In this case, the customer can use the two built-in sensors (temperature, position) and send readings + position to the cloud periodically or by a simple rule (threshold). This use case can be battery-operated or driven by a 5V power supply.
