FAQ

Q: Can the ESP32-S3-Pico be powered via pins?

A: Yes, you can use the VSYS pin for 5V power supply.

Q: Failed to flash the ESP32-S3-Pico?

A: If flashing fails, hold down the BOOT button while connecting to the computer, then release it before attempting to flash again.

Q: Is there a version of the ESP32-S3-Pico that supports CAN?

A: The ESP32-S3 has a CAN controller, but an external transceiver is required to implement CAN communication, which needs to be developed by the user.

Q: There are two rows of pin headers reserved on the PCB. What is the exact spacing between them in mm?

A: The exact spacing between the two rows of pin headers is 15.24 mm.

Q: If powered by 5V, how much current (mA) is required?

A: A minimum of 500 mA.

Q: Can the ESP32-S3-Pico support an external microphone and speaker?

A: A speaker requires an amplifier and cannot be connected directly to GPIO pins, so direct speaker connection is not supported. The microphone is I2S-driven and can be connected directly.

Q: Does the ESP32-S3-Pico have touch pins?

A: Yes, please refer to the manual for details.

Q: How many PWM channels does the ESP32-S3-Pico have?

A: It includes two MCPWM units, which can be used to drive digital motors and smart lights. For details, please refer to the link.

Q: Are the 1.47inch LCD Module and 1.69inch LCD Module compatible with this board?

A: Yes.

Q: Does the ESP32-S3-Pico have a built-in download circuit?

A: Yes, it includes an auto-download circuit.

Q: What is the maximum operating temperature for the ESP32-S3-Pico?

A: The recommended ambient temperature for the chip is –40 to 85 degrees Celsius.

Q: When controlling the onboard RGB LED (WS2812) on the ESP32-S3-Pico, why are colors displayed incorrectly (e.g., red appears green)?

A: This is due to a mismatch in color data order. The color data format for the onboard LED on the ESP32-S3-Pico is RGB (Red-Green-Blue). To resolve this, specify the color order parameter as RGB in the initialization settings of your driver library.
