Rich board resources: 400KB SRAM, 384KB ROM, 4M flash.

Chip model: ESP32S3FH4R2

Ultra-small size: As small as a thumb (22.52x18mm), classic shape, suitable for wearable devices and small projects

Reliable security features: Supports AES-128/256, hashing, RSA, HMAC, digital signatures, and encrypted hardware accelerator for security boot

Rich interfaces: 1x I2C, 1x SPI, 2x UART, 11x GPIO (PWM), 4x ADC

Built-in RGB, blue LED: Common GPIO48 pin

External power supply: If external power supply is needed, simply connect the + terminal of the external power supply to the B+ position on the back of the board, and the - terminal to the B- position on the back. (Supports 3.3～6V power supply). You can charge the battery by connecting to USB.

Note: When soldering, be careful not to short-circuit the positive and negative terminals, and do not damage the battery and the device.

The Com port on Arduino cannot be recognized

Enter download mode: Method 1: Press BOOT to power on. Method 2: Press the BOOT button of ESP32S3, then press the RESET button, release the RESET button, release the BOOT button, at this time ESP32S3 will enter download mode. (Each connection requires re-entering download mode. Sometimes pressing once, the port may be unstable and disconnected. You can judge by the sound of port identification.)

After uploading, the program cannot run

After successful upload, you need to press the Reset button to execute.

When plugged into the computer, the Com port does not show up, instead it shows (JTAG/serial debug unit)
