# ESP32-P4 chip capabilities This skill is the **chip layer**, not a board layer. A board skill (e.g. `m5stack-tab5`) tells you what's wired to what on one specific product; this skill tells you what the ESP32-P4 silicon itself can do — the peripherals, multimedia hardware, low-power modes, memory options, and concurrency model that are the same on every ESP32-P4 board regardless of vendor. Read a board's own skill first for pin numbers and I2C addresses, then come here when the user wants to go deeper on a capability than "call the vendor's high-level library and move on" — e.g. driving the MIPI camera pipeline, encoding H.264 in hardware, using the LP core while the main system sleeps, or getting real throughput out of USB HS OTG. ## The one thing every ESP32-P4 user needs to know: no radio, ever Unlike every other current ESP32 variant, **the P4 has zero wireless hardware** — no WiFi, no Bluetooth, no Thread/Zigbee/802.15.4. This isn't a stripped-down SKU; the chip was designed as a high-performance applications/HMI processor and pairs with a separate radio chip (an ESP32-C6 on M5Stack's Tab5 and Stamp-P4, most commonly) over SDIO or SPI when a project needs wireless. If a user asks "why won't `WiFi.begin()` compile/link" or "how do I get WiFi on my P4 board," the answer is always "it needs a companion radio chip and a host-side driver (ESP-Hosted or similar) talking to it" — not a missing library or wrong board setting. See that board's own skill (e.g. the `m5stack-tab
