Specifications

Full specifications for the ESP32-P4-WIFI6-DEV-KIT. All values are from the Espressif ESP32-P4 datasheet and Waveshare product documentation.

Processor

Parameter	Value
HP System	RISC-V 32-bit dual-core, up to 400 MHz (360 MHz current)
LP System	RISC-V 32-bit single-core
Co-processor	ESP32-C6 (WiFi/Bluetooth, connected via SDIO)
AI instruction extensions	Yes (HP system)
FPU	Single-precision floating point

Note

The HP (high-performance) system runs application code. The LP (low-power) system handles always-on tasks like sensor monitoring during deep sleep. The ESP32-C6 co-processor runs its own firmware and communicates with the P4 over the SDIO bus.

Memory

Region	Size	Notes
HP System ROM	128 KB	Boot code
LP System ROM	16 KB	LP boot code
HP L2 Memory	768 KB	Fast SRAM for HP system
LP SRAM	32 KB	Low-power system RAM
System TCM	8 KB	Tightly-coupled memory
PSRAM	32 MB	Stacked in ESP32-P4 package (octal SPI)
NOR Flash	16 MB	External QSPI flash

Tip

The 32 MB PSRAM is stacked directly inside the ESP32-P4 package, not on a separate chip. This reduces board area and improves signal integrity compared to external PSRAM modules.

Wireless (via ESP32-C6)

Parameter	Value
WiFi Standard	802.11ax (WiFi 6), 2.4 GHz
WiFi Features	Target Wake Time (TWT), OFDMA, MU-MIMO

Antenna	SMD antenna on ESP32-C6 module
Host Interface	SDIO

Display (MIPI-DSI)

Parameter	Value
Interface	MIPI D-PHY v1.1, 2-lane
Max Bandwidth	1.5 Gbps per lane (3 Gbps total)
Color Formats	RGB888, RGB666, RGB565
Hardware Acceleration	Pixel Processing Accelerator (PPA) + 2D-DMA
JPEG Decode	1080p at 30 fps
Supported Panels	5”, 7”, 8”, 10.1” DSI displays
Connector	FPC (on-board)

Camera (MIPI-CSI)

Parameter	Value
Interface	MIPI-CSI, 2-lane
ISP	Integrated Image Signal Processor
H.264 Encoder	1080p at 30 fps
Max Resolution	2 MP
Supported Sensors	OV5647 and compatible MIPI sensors
Connector	FPC (on-board)

Audio

Parameter	Value
Codec	ES8311 (I2S interface)
Amplifier	NS4150B (Class D, mono)
Speaker Output	MX1.25 2P connector, 8 ohm / 2 W
Headphone Output	3.5 mm stereo jack
Microphone	Onboard SMD MEMS microphone
Digital Interface	I2S

Connectivity

Interface	Details
USB 2.0 OTG	High-Speed (480 Mbps), HOST/DEVICE via jumper, USB-A connector
USB-C (UART)	CH343 USB-UART bridge, power + flash + debug
USB-C (USB)	Direct USB, power + flash
Ethernet	100 Mbps RJ45 with integrated magnetics
TF Card	SDIO 3.0 interface
I2C	Dedicated port (SCL: GPIO8, SDA: GPIO7)
I3C	Dedicated port
GPIO Header	40-pin, 27 programmable GPIOs

Power

Parameter	Value
Input Voltage	5 V via either USB-C port
PoE	Header for optional PoE module
RTC Battery	CR1220 holder (rechargeable cells only)
Power Indicator	Red PWR LED

Caution

The RTC battery holder is designed for rechargeable coin cells only. Do not install a standard non-rechargeable CR1220 — the charging circuit may cause it to overheat or leak.

Controls

Control	Function
BOOT button	Enter download mode (hold during reset)
RST button	Hardware reset
USB OTG jumper	Select HOST or DEVICE mode for USB-A port

Board dimensions

Parameter	Value
Form factor	Rectangular PCB with GPIO header
GPIO header	40-pin (2x20), 2.54 mm pitch

Operating conditions

Parameter	Value
Operating temperature	-40 C to 85 C (ESP32-P4 rated)
Humidity	5% to 95% RH (non-condensing)
