Introduction:

Lichee pi Zero (hereafter referred to as Zero) is a delicate mini Cortex-A7 core board/development board, which can be used for beginners to learn Linux or for product development. Zero offers a wealth of peripherals (LCD, ETH, UART, SPI, I2C, PWM, SDIO…) and powerful performance (~24M~1.2G, 64MB DDR**) on a slightly longer SD card size (~ 45x26mm).

Zero uses a compact PCB design that makes development and use very convenient:

  • Inline breadboard
  • Inline 40P RGB LCD
  • Use OTG port for power supply and data transmission (virtual serial port, virtual Ethernet, etc.)
  • Networking with stacked WiFi modules
  • Direct patch

Zero provides Mainline Linux support. You can use any programming you are familiar with on Linux.

The “2.54mm Pinout” means can be inserted directly into the breadboard or connected using standard DuPont wires.
The “1.27mm” mark is a pin that is less commonly used or inconvenient to manually wire. It is usually used during patching, or it can be used with a 2.54 pin to offset half of the needle position.
