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

Description

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.

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

LMS-ESP32 Documentation and hardware details

We maintain documentation on docs.antonsmindstorms.com. There is a special documentation page dedicated to the LMS-ESP32 board. We developed SerialTalk and mpy_robot_tools to make it easy to connect to this board. There are many example projects in these GitHub repositories.

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)
• I2S Microphone input for voice recognition (with optional I2S microphone)
• 4MB memory to compile the largest scripts.
• Micro-USB to connect to your laptop via Serial/UART/REPL and power the board too
• PWM up to 80MHz, 16 bit
• Can use the 8V from the MINDSTORMS or SPIKE hub to power 5V appliances

Of course, all of the existing functionality of the last WiFi Mindstorms Spike Board is still there:

• I2C
• Neopixel (ws2812) support
• Multiple Uart channels
• I2S
• Analog to Digital pins
• WebREPL
• Hotspot

Applications for the LMS-ESP32-v1.0 board

We designed this board with the following applications in mind:

• Stand-alone voice-controlled MINDSTORMS robots
• RGB LED-enhanced robots
• LEGO Robots with full-color touch screens
• Limitless I2C sensors, like laser range-finders
• Connecting to PS3 and PS4 gamepads and steering your robot directly

Basic, or Pro with jumper and Microphone

The board comes in two variants: basic and pro.

• The basic option includes all headers and ports to connect your robot. It also includes an LPF2/WeDo wire and a 5v buck converter for servos and LEDs. Flashed with the latest Micropython.
• The pro version also includes an I2S microphone and a grove jumper wire. Flashed with the latest Micropython.
