# T-HEAD SMART-EVB Introduction
SMART-EVB is a development board provided by T-HEAD, based on FPGA to provide implementation, integrating T-HEAD's RISC-V CPU (eg. E902/E906/C906) and C-SKY CPU (eg. E805/E804/E803/E802 ), integrates basic peripheral resources such as GPIO/TIMER/UART/RAM.

## The main resources on board are as follows:

1. SMART-EVB for T-Head CPU E9xx Series
