    Lychee Nano (hereinafter referred to as Nano) is an exquisite mini Arm9 core board/development board, which can be used for beginners to learn Linux or for commercial product development. Nano provides a wealth of peripherals (LCD, UART, SPI, I2C, PWM, SDIO, KEYADC...) and relatively strong performance (24M~408MHz, 32MB DDR) in the size equivalent to SD card (25.4*33mm).Lichee Nano Applications :

    IoT applications using more complex communication interfaces and protocols

    Applications that require a more beautiful and complex logic human-computer interaction interface

    Application scenarios that require more operations (compared to common MCUs)

    Scenarios that need to use RTT, open-source software packages under Linux for rapid development

    High-end geek players have a balance in size, performance, and ease of use.

    Entry-level players, software engineers, use familiar language for hardware DIY.

    Precautions
    Startup Nano needs card boot (or solder SPI flash), only plug-in USB without any phenomenon
    System debug serial port UART0, specific position reference pin diagram
    USB interface OTG USB, power and communication

    Please be careful when plugging and unplugging the Micro-USB. It is recommended that you put Solder on the two fixing feet of the USB socket after you get it

    Nano needs a card to boot (or welding SPI flash). Only plugging in the USB is basically no response, the screen has no output status, but you can start U-boot via USB without inserting the card and no flash.

    Nano's system debugging serial port is UART0, which is the two pins identified by "U0: Tx Rx" on the silkscreen of the board

    Simple usability testing, please refer to the next section, we need you in advance 1. Prepare a USB to TTL good welding tool 2. Pin 3. Connect the serial port 4. Prepare a Micro-USB cable
