The VAL-2000 is the easiest, fastest, cheapest, safest, and most wireless way to spin a stepper motor.
The firmware is pre-loaded, and no programming is required. Just plug in power and the motor, connect to it via Wi-Fi from a phone or computer, open up a browser, and begin using it right away.
Or integrate it with Home Assistant or any other device that can send REST API commands and automate the motor.
You can precisely control a motor's distance, speed, current, and stall characteristics within minutes of receiving it. No programming experience is required.
If you want to program it yourself, you can find the code here.
The VAL-2000 contains the following components in a very small package:
Setup only takes 3 minutes and 3 steps
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.
The VAL-2000 is already loaded with firmware to get you going right away.
Simply connect to it via WiFi and get the motor going right away.
The actual stepper driver is a TMC2226 which IS the TMC2209 in a larger form factor that can handle more current and better dissipate heat. I will refer to is as the TMC2209.
The Trinamic TMC2209 is one of the best stepper motor drivers on the market. It is very feature-rich while being affordable.
Easily program from the ESP32 via UART
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.
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.
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.
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.
In the unlikely event of an overcurrent, we've added a PTC thermistor for added safety.
Connect any 4-Wire Bipolar stepper motor
The 1A Synchronous DC/DC converter provides ultra-high efficient voltage regulation in a compact design.
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.
