🚀 Upload Code to ESP32-S3

Choose your preferred method to get your code running on the robot:

1

Install Arduino IDE

Download from arduino.cc/en/software (version 2.x recommended)

2

Add ESP32-S3 Board Support

In Arduino IDE, go to File → Preferences and add this URL to "Additional Board Manager URLs":

https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_index.json

Then go to Tools → Board → Boards Manager, search for esp32 by Espressif, and click Install.

3

Install Required Libraries

Go to Sketch → Include Library → Manage Libraries and install these (as needed by your project):

ESP32Servo · Adafruit NeoPixel · Adafruit SSD1306 · Adafruit GFX · Adafruit MPU6050 · Adafruit BMP280 · Adafruit TCS34725 · DHT sensor library

4

Configure Board Settings

Under Tools menu, set these exact board settings for the Bot Buddy ESP32-S3:

Setting	Value
Board	ESP32S3 Dev Module
USB CDC On Boot	Enabled
USB Mode	Hardware CDC and JTAG
Flash Size	16MB (128Mb)
Partition Scheme	16M Flash (3MB APP/9.9MB FATFS)
PSRAM	OPI PSRAM
Upload Speed	921600
Upload Mode	UART0 / Hardware CDC

5

Copy Code & Upload

Click Copy Code in the IDE toolbar, paste into Arduino IDE, select your port under Tools → Port, then click the Upload button (→).

1

Export Your Sketch

Click the button below to download your generated code as a .ino Arduino sketch file.

2

Open in Arduino IDE

Double-click the downloaded .ino file — Arduino IDE will open it automatically. It will ask to create a folder; click OK.

3

Set Board & Upload

Configure your board settings (see the "Arduino IDE" tab for exact settings), select your port, and click Upload.

💡 Tip: The .ino file is a standard Arduino sketch — you can also open it in PlatformIO or any Arduino-compatible IDE.

⚡

Flash Pre-Built Firmware from Browser

ESP Web Tools lets you flash pre-compiled Bot Buddy firmware directly from Chrome or Edge — no Arduino IDE needed. This is great for installing base firmware, factory resets, or running demo programs.

Connect your ESP32-S3 via USB-C and click Install:

⚠️ Requires Chrome or Edge. The ESP32-S3 must be in download mode (hold BOOT button while connecting). Firmware manifest URL can be configured at code.botbuddylabs.com/firmware/manifest.json

?

For Custom Code Upload

Browser flashing works with pre-compiled firmware binaries. To upload your own custom Blockly code, use the Arduino IDE or Export .ino tabs above. A fully browser-based compile-and-flash workflow is coming in a future update!
