📐 Dimension Info Module size: 57 X 28 X 12mm, Net weight:11.7g ⚠ Important Notes

1. GPIO26~GPIO32 are dedicated pins for onboard Flash and PSRAM, cannot be used as general IO ports.
2. ADC2 channels will be unavailable when WiFi is turned on; ADC1 (GPIO0-GPIO7, GPIO16-GPIO21) is recommended for priority use.
3. GPIO0, GPIO45, GPIO46 are strapping boot pins. Pull GPIO0 low to enter download mode.
4. GPIO19 and GPIO20 are native USB pins, can directly run USB host/device without extra chip.
5. To enable PSRAM on N16R8 version, select OPI PSRAM in tool menu.
6. CH340 driver needs to be installed for serial download and debugging.

🛠 Application Scenarios AI voice recognition, image recognition projects, smart home control, IoT wireless data transmission, USB device simulation (mouse, keyboard), low-power embedded equipment, electronic DIY, product prototype verification.
