esp32_s3_robotics

Basic experiments with the ESP32-S3 development board focused on IoT, robotics, and electronics fundamentals — mostly using MicroPython.

After ten years of experimenting and development, we are introducing a new universal module for robotics and programming.
At its core is the modern ESP32-S3 controller, combined with a power management module (including built-in Li-Ion battery charging).

The board connects via USB-C, which is used for programming, testing, and also for charging the battery.

Features

• Sufficient number of GPIO pins
• Two built-in LEDs (connected via jumpers)
• Two RGB LEDs
• Integrated accelerometer and gyroscope module
• Direct connection for up to eight servo motors

Installing the OctopusLAB framework is quick and easy using mip:

# mip_install.py # install octopusLAB framework 2

from time import sleep
import network
import mip

wlan = network.WLAN(network.STA_IF)
wlan.active(True)
sleep(5)

wlan.connect('ssid', 'password')
sleep(5)

mip.install("github:octopuslab-cz/esp32_micropython_framework/package.json", target=".")
