Key features and benefits Builtin PSRAM with USB TypeC interface Provides memory and a convenient, reversible USBC connection for easy setup and reliable data access. USB mass storage ready The USB port is recognized as mass storage, enabling simple draganddrop downloading without extra drivers or tools. Flexible data and power workflow The onboard USB port can function as a card slot bridge between USB and slave, allowing read and write operations on the card to manage charging and discharging the onboard battery. This supports mobile and onthego usage scenarios. Comprehensive hardware interface for development and integration Includes an onboard port, a card slot, a USB port, a 40pin GPIO header, and a reserved PSRAM port, designed to facilitate development, testing, and seamless integration into final products. Use scenarios Rapid prototyping and development Use the GPIO header for custom hardware interfaces, attach peripherals through the USBC port, and leverage the PSRAM for additional memory during development. The mass storage USB mode makes file transfer quick and straightforward. Mobile and field applications The card slot and onboard battery management capability enable data transfer and power control in mobile environments. The reversible USBC connection simplifies connection in tight or awkward setups. Final product integration The combination of USB, card access, GPIO, and a reserved PSRAM port provides a versatile platform for embedding into consumer electronics, IoT devices, or other products that require memory, multiple I/O options, and easy data transfer.
