# LicheePi Zero ## LicheePi Zero Introduction LicheePi Zero（called Zero follow）is a tiny **Cortex-A7** CoreBoard/DevelopmentBoard，and it is suit for embeded linux learner or product development/production. Zero is a bit longer than SD-card（~**45x26mm**）, but provide lot Peripherals（LCD,ETH,UART,SPI,I2C,PWM,SDIO...）and good performance（**24M~1.2G, 64MB DDR**）。 Zero is well designed in hardware, and it is easy to use: * breadboard-compatible * directly connect to 40P RGB LCD * use OTG to power and transmit data(virtual serial port, virtual ethernet) * stackable wifi module * SMT-compatible Zero provide **Mainline Linux** support and origin Camdriod (for DVR application)SDK， and you can use any program language on it. ## block diagram    ## Hardware Data ### Hardware Parameter * CPU：Allwinner V3S， ARM Cortex-A7, **1.2GHz** max * Memory：**64MB DDR2** integrated * Storage： * SOP8 **SPI Flash** for boot (Reserved)（8~32MB SPI Nor Flash,128MB Nand Flash customizable）; * **TF Card Slot** for boot. * Display： * General **40P RGB LCD** FPC， * Direct plug 40P 4.3/5/7 inch LCD（onboard backlight driver），plug 50P 7/9inch LCD via convert board. * support 272x480, 480x800,1024x600... * Onboard RTP chip, support touch screen * OnBoard **RGB LED** * Communication Interface * SDIO x2，(connect to SDIO WiFi+BT module) * SPI x1 * I2C x2 * UART x3 * 100M Ether x1（include EPHY） * OTG USB x1 * MIPI CSI x1 * Other Interface * PWM x2 * LRADC x1 * Speakerx2 + Mic x1 * Electrical Characteristics * Power Input: Micro USB 5V； 2.54mm pins 3.3V~5V； 1.27mm holes 3.3V~5V * Power Output: 3.3V and 3.0V（AVCC） * 1GHz linux IDLE run 90~100mA; cpu-burn run ~180mA * Storage Temperature -40~125℃，Operation Temperature -20~70℃ * Size: 44.6x25.5mm ### Sheet&Data NetDisk：http://pan.baidu.com/s/1eR6uIsy Datasheet：http://ilichee.cc/doc/V3S/Allwinner_V3s_Datasheet_V1.0.pdf SCH：http://ilichee.cc/doc/SCH_PCB/lichee_zero.pdf PCB Lib：http://ilichee.cc/doc/SCH_PCB/Zero.IntLib ### Pins Definition
