Expansion Board Module for Lichee Zero LicheePi Zero Raspberry Pi V3S Developments Board Mini Cortex-A7 Core Wholesale  Lichee Zero product introduction:  The Lai Chi School Zero is a compact mini Cortex-A7 core board/development board for beginners to learn Linux or commercial product development. The Lichee School Zero was conceived from the end of last year. The design goal is a Pi that meets all the good ideas of makers and embedded engineers: low cost, small size, high performance, easy to use, and more expansion. Application scenario IoT applications using more complex communication interfaces and protocols The application of human-computer interaction interface that needs more beautiful and complex logic  Application scenarios that require more operations (as opposed to common MCUs)  Need to use open source software under Linux for rapid development scenarios  High-end geek players balance their size, performance and ease of use.  Entry level player, software engineer, hardware diy using familiar language.  Development board features  Based on Allwinner V3s (ARM Cortex-A7 CPU, 1.2GHz, 512Mbit DDR2 integrated)  Bootable from onboard SPI Nor Flash (SOP8 16MB / WSON8 32MB) or TF card  Support multiple development languages  Straight into the breadboard, while the full-stamp stamp hole leads out  Low-speed peripherals UART, SPI, I2C, PWM, ADC  High-speed interface OTG USB, MIPI CSI, EPHY, RGB LCD  Reserve flash interface, TF card slot  FPC40 can be connected to RGB LCD, VGA adapter board, high speed DAC module  FPC24 can be connected to DVP camera, high speed ADC module  Camera interface DVP+MIPI  The development board integrates a variety of peripherals: audio port, microphone, multi-button, network port, etc.
