Machine interfaces

For a tighter integration with the customer's systems, the device supports a number of communication interfaces - see below. These can be used with out open-source communication library. Please contact us if you have any questions!

Interface name Description
Implementation status
USB (Virtual Serial Port)
Simply plug our machine into USB and install suitable drivers (available for Windows, Mac and Linux). Real-time output
Included on every machine & supported by our communication library but not enabled by default. See Note 1.
Bluetooth 4/LE
Wirelessly receive measurements in real time using this standard (but somewhat complex) interface. Real-time output.
Included and enabled on every machine - in use when communicating with our devices with our app. Supported by our communication library.
CAN (TWAI) bus
Network interface primarily used in the automotive industry. Can support a large number of devices with only 2 wires. Real-time output.
Supported and in commercial use by a customer. Custom board  required and an additional connector is also required – a surcharge will apply. See Note 2.
UART (serial port)
This interface is primarily useful for communicating with small microcontrollers that don’t support USB. Real-time output.
No board change required (so included on every machine) but a special connector will need to be added – a surcharge will apply.
I2C (Master mode)
This interface is primarily useful for communicating with small microcontrollers that don’t support USB. The interface is shared with the device screen and possibly other internal peripherals.
No board change required (so included on every machine) but a special connector will need to be added – a surcharge will apply.
Matoha Data API Our devices can report measurement results to our Cloud, from where the customer can retrieve them. See using our data API. The results can be delayed by up to 5 minutes - not real-time!
Included with every device – needs Wi-Fi connection.

Note 1: Powered USB hub required (machines shipped before Apr 2022 draw up to 2 A, from April 2022 up to 1 A; standard computer USB supports 0.5 A). Performance might be deteriorated if sufficient power is not supplied to the device - we only guarantee function & performance with the adapter supplied with the device.


Note 2: There is a major worldwide shortage of CAN interface chips, with lead times on these chips exceeding 1.5 years. We do have some in stock but would advise against using CAN unless you really have to.
