The VAL-1000 is the fastest and easiest way to control a stepper motor over WiFi and Bluetooth. Simply download our app, connect a motor and get spinning! Or upload your own Arduino code and have all the fun you want.

The VAL-1000 contains the following components in a very small package.

• Espressif ESP32 dual-core wifi controller
• Trinamic TMC2209 motor driver with StallGuard and StealthChop
• Texas Instrument synchronous 12V to 3.3V DC/DC converter
• Silicon Labs USB/TTL bridge
• Two limit switch inputs
• Two button inputs

This board includes everything you need to quickly add the most advanced stepper motor driver on the market to your project.

Setup

Setup only takes 3 minutes and 3 steps

1. Connect any bipolar (4-wire) stepper motor
2. Connect a 12V 2A+ power cord (2.1mm x 5.5mm barrel connector)
3. Download the iOS or Android app (optional) And that's it!

If you love to program, that's great! We've made it extremely simple to do so. Simply download the source code on Github and plug in a USB cord to quickly flash your new firmware.

WiFi Control

The VAL-1000 is already loaded with firmware to get you going right away.

In addition, our iOS and Android app allow you to connect this board to your WiFi network and begin to control it right away.

Also, set up MQTT in the app to integrate it with Home Assistant.

Detailed Features

Trinamic TMC2209

The Trinamic TMC2209 is one of the best stepper motor drivers on the market. It is very feature-rich while being affordable and completely silent.

The TMC2209 also includes the extremely popular and useful StallGuard feature. Easily set it to stop whenever the force on your motor exceeds a certain force. This makes it very safe to use for all types of projects.

Micro USB Port

Easily flash the firmware using the micro USB port and CP2104 USB-to-UART Bridge. We've also included the automatic flashing circuit so you don't have to open up your device and press G0 and Reset. Everything is automatic.

Two Buttons

Sometimes it's nice to press a button to open or close your device. That's why we've included two buttons to do just that.

Dual Sensor Connectors

If you want to connect two limit switches or any other type of sensor, we've included 6 pins for that. You will get access to two GPIO, two GND, and two 3.3V pins to make it simple to connect.

PTC Thermistor

In the unlikely event of an overcurrent, we've added a PTC thermistor for added safety.

Stepper Motor

Connect any 4-Wire Bipolar stepper motor

On-Board Voltage Regulator

The Texas Instruments TPS62162DSGR 1A Synchronous DC/DC converter provides ultra-high efficient voltage regulation in a compact design.

ESP32-WROOM-32D (16MB)

This dual-core ESP32 sits at the heart of the board. Its low-cost to high-performance ratio is unlike any other. It provides stepper motor control as well as maintains the wireless connection for WiFi and MQTT access
