# Installing MicroPython on Lonely Binary ESP32-S3: Complete Guide
## Overview
The Lonely Binary ESP32-S3 is a powerful dual-core microcontroller from Espressif that features WiFi, Bluetooth, and enhanced security features. Installing MicroPython on theLonely Binary ESP32-S3 opens up a world of possibilities for IoT projects, embedded systems, and rapid prototyping.
This guide will walk you through the complete process of installing MicroPython on yourLonely Binary ESP32-S3, from preparing your development environment to running your first program.
## Step 1: Prepare Your Development Environment
### Install Thonny IDE
Thonny is an excellent IDE for MicroPython development with built-in support for ESP32 boards.
**Download from:** [thonny.org](https://thonny.org/)
## Step 2: Download MicroPython Firmware
### Official MicroPython Firmware
1. Visit the official MicroPython downloads page: [https://micropython.org/download/ESP32_GENERIC_S3/](https://micropython.org/download/ESP32_GENERIC_S3/)
2. Download the latest firmware for Lonely Binary ESP32-S3:
- **Standard build (without PSRAM)**: - For boards without external PSRAM
- **With PSRAM support**: - For boards with external PSRAM
**For Lonely Binary ESP32-S3 (8MB External PSRAM):** Download the **PSRAM version**
This build includes support for external PSRAM, which is essential for boards with additional memory like the Lonely Binary ESP32-S3.
## Step 3: Connect YourLonely Binary ESP32-S3
### Physical Connection
1. Connect yourLonely Binary ESP32-S3 to your computer using a USB-C cable
2. Ensure the cable supports data transfer (not just charging)
### Driver Installation
**Windows:**
-Lonely Binary ESP32-S3 typically uses a CH340K USB-to-UART bridge
- Download drivers from WCH website
**macOS:**
- Drivers are usually included with macOS
- If needed, install CP210x drivers from Silicon Labs
### Verify Connection
Check if your computer recognizes theLonely Binary ESP32-S3:
**Windows:**
- Open Device Manager
- Look for "USB Serial Device" or "CH340 USB to UART Bridge"
**macOS/Linux:**
```bash
ls /dev/tty.*
# Look for something like /dev/tty.usbserial-0001 or /dev/ttyUSB0
```
## Step 4: Flash MicroPython Firmware
1. Open Thonny
2. Go to **Tools** → **Options** → **Interpreter**
3. Select **MicroPython (ESP32)**
4. Select your port from the dropdown
5. Click **Install or update MicroPython**
6. Choose **Select local firmware** , the firmware file you downloaded
7. Click **Install**
## Step 5: Verify Installation
### Connect to REPL
**Using Thonny:**
1. Open Thonny
2. Select **MicroPython (ESP32)** as interpreter
3. Select yourLonely Binary ESP32-S3 port
4. Click **Connect**
5. You should see the MicroPython prompt: `>>>`
### Test Basic Commands
```python
# Test basic functionality
print("Hello,Lonely Binary ESP32-S3!")
```
