Short, task-oriented guides. Each one answers a real question people ask about a supported board — what the documentation says, what it does not say, and where the fixed sources live.

Start here, by task

• “I just unboxed a board.” — Getting started with the Raspberry Pi Pico · ESP32-S3-DevKitC-1 first connection and flash · ESP32-DevKitC V4 first connection and flash
• “Which one do I have?” — Which ESP32-S3-DevKitC-1 do I have? · Pico vs Pico 2
• “The computer sees nothing.” — USB board not detected
• “Can I use this pin?” — GPIO35/36/37 on the DevKitC-1 · why the onboard LED is GPIO38 or GPIO48

Concepts every tutorial assumes

• Chip, module, board — the three layers
• Pin numbers, GPIO numbers and pin functions
• 3.3 V and 5 V — power rails, logic levels
• UART, I2C and SPI

By board family

• ESP32 guides — ESP32-S3-DevKitC-1 identification, revisions, pins and first flash; ESP32-DevKitC V4 bring-up.
• Pico guides — first steps and generation choice for the Raspberry Pi Pico.
• Troubleshooting — the observable-breakpoint checklists.
