By default, the onboard SPI flash connected to the ESP32-P4 chip operates at a maximum clock frequency of 80 MHz and does not support the auto suspend feature. If you have a requirement for a higher flash clock frequency of 120 MHz or if you need the flash auto suspend feature, please contact us.

Note

Usage notes for LDO_VO3 / LDO_VO4:

On the ESP32-P4X-C5-Function-EV-Board, LDO_VO3 and LDO_VO4 are used to power certain on-board VDD domains. Users must configure the correct output voltage and enable state in software.

In Light-sleep or Deep-sleep mode, if LDO_VO3 / LDO_VO4 remain enabled, the system power consumption will be relatively high. Even when turned off, the total power consumption may still exceed the typical low-power specifications listed in the chip datasheet due to the board-level power architecture.

For applications with strict power consumption requirements, it is recommended to optimize the power architecture in custom hardware designs.

Accessories

Optionally, the following accessories are included in the package:

• LCD and its accessories (optional)

  • 7-inch capacitive touch screen with a resolution of 1024 x 600

  • LCD adapter board

  • Accessories bag, including DuPont wires, ribbon cable for LCD, long brass standoffs (20 mm in length), and short brass standoffs (8 mm in length)

• Camera and its accessories (optional)

  • 2MP camera with MIPI CSI

  • Camera adapter board

  • Ribbon cable for camera

Ribbon Cables in Forward and Reverse Directions

Note

Please note that the ribbon cable in the forward direction, whose strips at the two ends are on the same side, should be used for the camera; the ribbon cable in the reverse direction, whose strips at the two ends are on different sides, should be used for the LCD.

Application Examples

The following application examples are available for ESP32-P4X-C5-Function-EV-Board:

• ESP_Brookesia Phone - Demonstrates an Android-like interface with multiple applications using ESP_Brookesia, utilizing MIPI-DSI, MIPI-CSI, ESP32-C5, SD card, and audio interfaces on the development board, providing a basis for efficient multimedia application development.

Alternatively, you can try the factory demo and other prebuilt examples directly in your web browser using ESP Launchpad. ESP Launchpad provides a convenient way to flash firmware to your board without installing ESP-IDF or compiling the source code.

To explore the application examples or to develop your own, please follow the steps outlined in the Start Application Development section.

Start Application Development

This section describes how to set up the hardware and software, and how to flash firmware onto the development board for application development.

Required Hardware

• ESP32-P4X-C5-Function-EV-Board

• USB cable

• Computer running Windows, Linux, or macOS

Note

Be sure to use a USB cable that supports data transfer. Some cables are for charging only and cannot be used for data transfer or programming.

Optional Hardware

• MicroSD card

Power Supply Options

The board can be powered in any of the following three ways:

• Via the USB 2.0 Type-C Port

• Via the USB Full-speed Port

• Via the USB Serial/JTAG Port

If the USB cable used for debugging cannot provide enough current, you can connect the board to a power adapter via any USB Type-C port.

Hardware Setup

Connect the ESP32-P4X-C5-Function-EV-Board to your computer using a USB cable. The board can be powered through any of the USB Type-C ports. The USB Serial/JTAG Port is recommended for flashing firmware and debugging.

To connect the LCD, follow these steps:

1. Secure the development board to the LCD adapter board by attaching the short brass standoffs to the four standoff posts at the center of the LCD adapter board.

2. Connect the J3 header of the LCD adapter board to the MIPI DSI connector on the ESP32-P4X-C5-Function-EV-Board using the LCD ribbon cable (reverse direction). Note that the LCD adapter board is already connected to the LCD.

3. Use a DuPont wire to connect the GPIO27 pin of the J1 header on the ESP32-P4X-C5-Function-EV-Board to the RST_LCD pin of the J6 header on the LCD adapter board. The GPIO mapped to RST_LCD can be configured via software, with GPIO27 set as the default.

4. Use a DuPont wire to connect the GPIO26 pin of the J1 header on the ESP32-P4X-C5-Function-EV-Board to the PWM pin of the J6 header on the LCD adapter board. The GPIO mapped to PWM can be configured via software, with GPIO26 set as the default.

5. It is recommended to power the LCD by connecting a USB cable to the J1 header of the LCD adapter board. If this is not feasible, use DuPont wires to connect the 5V and GND pins of the J1 header on the ESP32-P4X-C5-Function-EV-Board to the 5V and GND pins of the LCD adapter board, provided that the development board has sufficient power supply.

In summary, the ESP32-P4X-C5-Function-EV-Board and the LCD adapter board are connected via the following pins:

DuPont Wire Connections

ESP32-P4X-C5-Function-EV-Board	LCD Adapter Board
MIPI DSI connector	J3 header
GPIO27 pin of J1 header	RST_LCD pin of J6 header
GPIO26 pin of J1 header	PWM pin of J6 header
5V pin of J1 header	5V pin of J6 header
GND pin of J1 header	GND pin of J6 header

6. Attach the long brass standoffs to the four standoff posts on the periphery of the LCD adapter board to allow the LCD to stand upright.

Note

• If you power the LCD adapter board by connecting a USB cable to its J1 header, you do not need to connect its 5V and GND pins to the corresponding pins on the development board.

• To use the camera, connect the camera adapter board to the MIPI CSI connector on the development board using the camera ribbon cable (forward direction).

Software Setup

After completing the hardware setup, please follow ESP-IDF Get Started to set up your development environment and flash an application onto your board.
