1. Posicionamento central & Board Differences

Module Definition

“Module” refers to a modular full-featured development board, built on a pre-packaged ESP32-P4 core module rather than a bare chip design.

Compared to ESP32-P4-NANO:

• Larger size
• More GPIOs and interfaces
• Stronger expansion capability
• Closer to the functionality of official Espressif evaluation boards

Dual-Chip Architecture

• Main chip: ESP32-P4 (high-performance dual-core RISC-V)
• Co-processor: ESP32-C6-MINI (Wi-fi 6 + BLE via SDIO 3.0 high-speed interface)

Observação: The ESP32-P4 itself does not include native wireless capability. All wireless functions are handled by the C6 module.

Dimensões

• Approx. 85 × 56 milímetros (standard development board size)
• Onboard 40-pin GPIO header (partially compatible with Raspberry Pi HATs)
• Easy connection to sensors, exibições, e módulos externos
