DeviceTone® Technical Specifications

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.

Overview

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.
