FPGA 英文全称为 Field Programmable Gate Array (现场可编程逻辑阵列)，<br>特点是用户可以自行定义芯片内部数字逻辑<br>

一般来说，在 MCU 或者简单的逻辑芯片满足不了当前需求时，<br>就应当选择 FPGA 了。主要有以下方面的用途：
|
||||
<p align="left">
|
||||
①: 协议转换；比如一路 SPI 转十路 IIC<br>
|
||||
②：数字信号处理；FPGA 内部可以同时处理多路数据<br>
|
||||
④：逻辑验证；自己最低成本在现实中复现自己设计的数字电路逻辑

Tang FPGA 各自特点如下：<br>
|
||||
<strong>Tang Nano 1K：</strong> 最实惠的 FPGA 开发板，可以用来做一些简单的接口转换或者低成本体验 FPGA<br>
|
||||
<strong>Tang Nano 4K：</strong> 性价比高的异构 SOC FPGA 图像开发板， 可以学习 AHB 总线和图像入门处理<br>
|
||||
<strong>Tang Nano 9K：</strong> 逻辑单元足够验证软核的 FPGA，适合于验证自己的数字逻辑电路<br>
|
||||
<strong>Tang Nano 20K：</strong> Tang Nano 9K 的升级款，逻辑单元容量加倍，体积更小<br>
|
||||
<strong>Tang Primer 20K：</strong> 内存条样式封装的 FPGA 核心板，适合集成在自定义地板上<br>
|
||||
<strong>Tang Primer 20K Dock：</strong> 基于 Tang Primer 20K 核心板的多功能开发板，多种外设适合 FPGA 入门<br>
|
||||
<strong>Tang Primer 20K Lite：</strong> 基于 Tang Primer 20K 核心板的最简拓展版，适用于自己设计外部拓展<br>
