Product Introduction
Introduction to i3128Core Board
Product Overview
The I3128 is a core board developed by Shenzhen 9Tripod Technology Co., Ltd. It is based on the processor platform described in the original manual and is intended for embedded and industrial applications.
I3128CV1Core Board is widely used in human-computer interaction, intelligent control systems, portable handheld projectors, set-top boxes, medical, automotive, POS and other fields. It is especially suitable for cost-sensitive application scenarios with high performance requirements.
Core Board Features
I3128CV1Core Board has the following features:
The optimal size ensures that all GPIO ports are accessible while the size is only 38mm*38mm;
Using RK's own RK816 PMU, the cost is low enough while ensuring stable and reliable operation;
supports eMMC of multiple brands and capacities;
Using single-chip DDR3 design, supports 512MB/1GB/2GB capacity, default 512MB;
supports power sleep wakeup;
supports Android6.0, Linux and other operating systems;
supports SPI, I2C, UART and other communication buses;
supports Gigabit wired Ethernet;
The product is stable and reliable. After a large number of high/low temperature, repeated reboot, Android stability test, Antutu test and other reliability experiments, the machine did not crash for 7 days and 7 nights;
