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.
