Maxim MAX15062 High-efficiency Voltage Regulator The ATECC508A can store up to 16 keys and communicates on the I2C bus. This device is popular in industrial, home automation, medical, and IoT applications. The Microchip ATECC508A crypto-authentication module supports the ECDH (Elliptic Curve Diffie–Hellman) key agreement, allowing it to provide authentication without the need for secure storage. Microchip ATECC508A Crypto-authentication Module The powerSTEP01 can provide stepping modes of up to 1/128 microstep. It communicates using the SPI bus at 5Mbits. The powerSTEP01 has its own integrated controller that provides full control of the stepper motors speed and position. On the WiFi Stepper, this chip has been provided with a heatsink to keep it running cool. It features overcurrent and overtemperature and motor stall protection. The powerSTEP01 is a stepper motor driver chip that uses 8 N-channel power MOSFETs to allow it to drive motor coils at up to 85 volts at 10 amperes. The board brings out several of the ESP8266 connections to a male header, allowing experimenters to make further use of the capabilities of the WiFi chip. The WiFi Stepper uses the small form-factor ESP-WROOM-02 package of the ESP8266 in its design. It’s low-cost and ability to be programmed using the popular Arduino IDE has made it a favorite component with makers and hackers. Manufactured by Espressif Systems, the ESP8266 combines a WiFi interface with a microcontroller. This chip has been a popular component in many DIY electronics projects and is featured in many commercial designs as well. ESP8266 WiFi Controllerįor many of you, the ESP8266 requires no introduction. Let’s examine these components in more detail.

The WiFi Stepper consists of four key components:

The web-based interface simplifies both controlling the stepper motor and writing Bash and Python scripts. This module is perfect for IoT, robotics, home automation, and other projects where running control connections to the stepper motor controller would be impractical. 10-bit Analog to Digital Converter input.Supports an external stop and reverse switch.Allows a stepper motor to emulate a servo motor.Several security features to secure your installation.

Has a JSON API to allow control using a script on a remote computer.

Has a full-featured web-based user interface.

Supports bipolar stepper motors rated at up to 85 volts at 10 amperes.

The Wifi Stepper has several impressive features: It is currently being crowdfunded on the Crowd Supply fundraising platform. The Wifi Stepper was developed by Andrew Klofas of Good Robotics.
