The BLE Stepper Motor Analyzer is a low-cost, open source system that analyses stepper motor signals and displays the data in real time on a computer screen. The system includes two parts: The Device, which extracts information such as steps, and speed, and transmits the data via Bluetooth BLE, and the App that runs on a Windows, Mac OSX, or Linux PC, and displays the stepper information in real time in a graphical view.

Stepper Motor Analyser Design Highlights

The device is passive and does not interfere with the operation of the stepper motor, regardless if it is in use or turned off. Furthermore, the stepper signals are galvanically isolated from the electronics.

Embedding the device in a 3D printer is simple. It has a small footprint, operates on 7-30 VDC, and can use a small external sticker antenna that overcomes shielding by the printer enclosure.

The device firmware can upgraded by users using a standard USB cable, no tools or adapter required.

Each device has its fixed unique address such that multiple devices can be used and addressed independently (e.g. one for each stepper motor in your printer).

Open BLE and Python APIs supports custom monitoring apps, such as specialized analysers or mobile apps.
