For Nano is a mini development board based on F1C100s(ARM 926EJS ) high-performance SOC chip design The development board design is small and delicate, all the resources of the chip are drawn out, such as USB, Flash, TF card, 40P LCD interface, etc., and all the IO resources are drawn out, convenient for developers to expand the use, suitable for beginners to learn Linux For Nano is a SD card sized Linux development board powered by the Allwinner F1C100s ARM9 processor. For Nano 22 CPU: Allwinner F1C100s, ARM 926EJS processor, up to 900MHz Memory and storage: 32MB DDR integrated into SoC, 16MB SPI Flash Onboard TF slot, can be booted from TF card, Display: 40-pin RGB LCD FPC connector, supports 272x480, 480x800, 1024x600 And other resolution resistive displays (and capacitive displays through the adapter board). Support 720P video output, support video decoding such as 264 / MPEG Communication Interface: SDIO for WiFi module SPI x2, TWI x3, UART x3 OTG USB x1, TV output Other interface: PWM x2, LRADC x1 Headphone output x2, Mic x1 Name: Development Board Type: For Nano Set: B color:Black :PCB Package Contents: 1 x 5 inch resistance screen Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the a little different from the real thing. The measurement allowed error is +/- 1-3cm.
