Core Specifications

• Processor: Xtensa 32-bit LX7 dual-core processor operating up to 240MHz.
• Memory: Built-in 512KB SRAM, 384KB ROM, paired with high-capacity 8MB to 16MB Flash and 8MB PSRAM.
• Connectivity: Integrated 2.4GHz Wi-Fi (802.11 b/g/n) and Bluetooth 5.0 / BLE with an onboard antenna.
• Display: 4.3-inch IPS LCD panel featuring an 800×480 high resolution and 65K colors.
• Touch Interaction: Capacitive multi-touch panel supporting precise 5-point touch control managed over an I2C interface.

Peripheral Interfaces & Expansion

• Industrial Protocols: Onboard interfaces for CAN and RS485 communication lines.
• Storage Expansion: A dedicated MicroSD/TF card slot for loading asset heavy assets like images, UI themes, or log data.
• Device I/O: Integrated full-speed USB port along with accessible I2C pins for secondary sensors or peripherals.

Key Software & Usability Advantages

• Optimized Graphic Performance: The high-capacity PSRAM allows developers to smoothly compile and run complex Graphic User Interface (GUI) frameworks, such as the Light and Versatile Graphics Library (LVGL), for modern fluid animations and menus.
• Efficient Power Design: Supports customizable clock control and independent module power supply settings to minimize current consumption during deep-sleep or idle runtime states.
