ESP32-P4

The big one. 400 MHz across two cores, MIPI displays and cameras, and real headroom for interfaces that used to need a Pi.

Before you plan anything

No radio at all. No Wi-Fi, no Bluetooth, nothing.

This is not a limitation to work around — it is the design. If your project needs a network, the P4 needs a second chip beside it. We ship a C6 companion in the box for exactly this reason.

For touchscreens and camera work. Ships with a C6 companion module, because networking needs a second chip.

The pins that matter

Not all forty-odd of them. The five rows that decide whether your wiring works.

Default I2Cassign any GPIOThe core ships no default for this board yet. Pass your pins to Wire.begin() explicitly.

MIPI displaydedicated DSI pinsNot GPIO. They go to a flat-flex connector, not to header pins or jumper wires.

MIPI cameradedicated CSI pinsSame story. A camera needs the right FPC cable, not a breadboard.

Companion radioSDIO or UARTHow the C6 attaches. Our board profile fixes the four SDIO pins so the examples just work.

unverifiedThis chip is new enough that core defaults are still moving. Rows marked in orange are what we measured on our own board, not what a datasheet promised.

What catches people out on this chip

These are the support emails. They exist nowhere else on the site because they are true of nothing else.

It has no Wi-Fi, and people keep discovering that after buying

There is no antenna, no MAC, no radio block on the die. Networking happens through a companion chip over SDIO, and every network guide on this site is marked as not applicable to a bare P4.

MIPI is not a breadboard interface

DSI and CSI run at hundreds of megahertz on impedance-matched traces. You need the right flat-flex cable and a screen that matches it. Jumper wires will not work at any length.

400 MHz is not a battery figure

Two cores at 400 MHz with 32 MB of PSRAM is a mains-powered profile. If your project runs on a cell, the C3 or C6 is the honest answer.

The toolchain is the newest thing here

IDF support landed first, Arduino second, MicroPython third and partially. Check what your language actually supports before committing the design.

Modules that work with the ESP32-P4

Sensor and display modules work normally through GPIO, I2C and SPI. Anything that assumed the board could reach the internet on its own needs the companion radio first.
