Designed and open-sourced by Zapta and later modded by Adam from Vector3d.com the BLE Stepper Motor Analyzer (‘the analyzer’) is a low-cost, open source system that analyzes stepper motor signals and display the the data in real time on a computer screen through a bluetooth connection.
We have upgrade the board to v1.4.2.e and it features:
- ESP32-WROOM-32E-N4 with inbuilt integrated antenna. No need to attach an external antenna.
- grounded fixing mounts for an extra layer of security
Whats the aim of this board?
Check if your stepper motors are answering correctly to max speed and accelerations from your machine. Maybe in a near future we can have more conclusions.
What do you need?
The Stepper Motor Analyzer (‘this board’). This is a small electronic board that monitors the currents through the stepper motor wires, extracts information such as steps, and speed, and transmits the data via Bluetooth BLE. Our board has the ESP32-WROOM-32E-N4 MCU with inbuilt antenna. With this specific version there is no need for an external antenna. We also pre-flash the board with the correct firmware and for that reason there is no need to provide a USB-C Cable. You will receive: 1x Board + 2x JST 4P connector + 1x JST 2P connector + 10 terminal crimps. If you need cables please check our heluflon 0.25mm
The Analyzer App (‘the app’). This is a Python program that runs on a Windows, MaC OSX, or Linux PC, and displays the stepper information in real time in a graphical view. It can be downloaded here https://github.com/zapta/ble_stepper_motor_analyzer/archive/refs/heads/main.zip If you are running windows open: release/windows/analyzer.exe You will need a computer with bluetooth enabled.
