WiFi Python LMS-ESP32 board for MINDSTORMS (LMS-ESP32-v1.0)


SKU: N/A Category:


This all-new MicroPython expansion board for LEGO MINDSTORMS Robot Inventor, Spike Prime, and EV3 is even more potent than the last Wifi Board. You can easily connect this LMS-ESP32-v1.0 board to your LEGO robot and use it as an interface to a limitless range of third-party electronics. You can now connect any protocol to your LEGO Robot: I2C, UART, SPI, WS2812, Neopixel, I2S, WiFi, Bluetooth Classic, BLE, Bluetooth HID, Hobby Servo PWM, and many more.

It has a full set of libraries and instructions to help you communicate with your LEGO Intelligent Brick or Hub.

NEW! The boards come completely pre-soldered. No more soldering on your part!

New possibilities for your LEGO Robot with the LMS-ESP32-v1.0

The new ESP32 board has all the features of the previous Wifi Board for SPIKE and MINDSTORMS but adds these possibilities:

  • Bluetooth support for both BLE and Bluetooth classic.
  • WiFi support
  • 5V and 3V3 rail for powering hobby servos (with optional buck converter)
