Specifications at a glance Processor: Xtensa 32bit LX7 dualcore, up to 240 MHz main frequency Wireless: 2.4 GHz WiFi (802.11 b/g/n) and Bluetooth 5 (LE), with onboard antenna Memory and storage: 512 KB SRAM, 384 KB ROM, 16 MB Flash, 8 MB PSRAM Display: Onboard 2.8 inch LCD, 480x640 resolution Interfaces: UART, I2C, etc., with fullspeed USB port Peripherals and sensors: Onboard QMI8658 6axis sensor, RTC sensor, TF card slot, battery recharge management module, and related components What sets it apart Compact, integrated development and deployment platform combining a capable processor, wireless connectivity, onboard display, memory, and multiple sensors and peripherals in a single unit. Ready for projects requiring local UI, offline data logging, and wireless communication without external modules. Flexible IO and expansion options support rapid prototyping and integration into larger systems. Applications and use scenarios Wireless sensor hub for industrial or environmental monitoring: collect data via the 6axis sensor and other IOs, log to TF card, display status on the 2.8 inch screen, and transmit data over WiFi or Bluetooth as needed. Portable handheld data logger: ondevice display shows live metrics, store data locally on the TF card or Flash, and sync wirelessly to a host or cloud when connectivity is available. Smart home controller or prototyping board: manage and monitor peripherals through UART/I2C and other IO, provide a local user interface on the LCD, and connect to other devices via WiFi or BT for automation tasks. Notes Onboard antenna provides integrated wireless capability. Includes battery recharge management module for power management and charging workflows.
