Let’s say you have a project that requires a single stepper motor that you want to control wirelessly. For that to work, you’ll need the stepper motor, a Wi-Fi development board like a ESP8266, a stepper driver, a power supply for the microcontroller, and possibly a separate power supply or regulator for the stepper driver. That’s a lot of components just to handle a fairly simple task, which is why the new Wi-Fi Stepper stands out.
The Good Robotics Wi-Fi Stepper is a single board that offers everything you need to control one stepper motor through Wi-Fi, and it can handle stepper motors all the way up to 85V and 10A rms. To use Wi-Fi Stepper, all you have to do is plug in a power supply and the four wires from your stepper motor. The board will automatically launch a web interface that you can use to control the stepper, or you can use the JSON API or Python library for custom interactions.
That’s all possible thanks to the combination of four components: an ESP8266 module, a powerSTEP01 stepper motor driver, a MAX15062 voltage regulator, and an ATECC508A crypto authentication module. The Microchip ATECC508A chip provides security against unauthorized access. And, because Wi-Fi Stepper is built around the popular ESP8266 module, you’ll have easy access to the UART serial port, I2C bus, and ADC so you can integrate it with other components.
Wi-Fi Stepper is launching soon on Crowd Supply, so sign up for updates so you can back it when it does.
UPDATE: The campaign is now live at a price tag of $59, while a quickstart kit can be picked up for $100.
