Figure 2-1. ESP32 Pin Layout (, Top View) 意味着这是 ESP32 芯片的引脚布局图,采用的是 QFN 6*6 封装,而且是从芯片的顶部(俯视图)观察的布局。 1、This is the basic tutorial and should be used as template for other tutorials.中文(简体)这是基本教程,应用作其他教程的模板。 Build and Flash ...
打开芯片手册,然后找到pin definitions页面,这里主要查看一些特殊功能的引脚,例如adc、uart、spi用的是哪些io,确定下来后,把其它的通用IO也逐一确定即可,这些通用的IO后续绘制原理图时,还可以调整。 手册与设计资料:www.st.com 打开芯片手册,然后找到pin definitions页面,这里主要查看一些特殊功能的引脚,例如adc、uart、...
外设和GPIO对S3来说相对就弱一点,共计仅有56pin的MCU,其中45pin可编程 GPIO,通过IO矩阵重映射所有端口这点非常方便PCB layout,支持常用外设:SPI、I2S、I2C、PWM、RMT、ADC、DAC、UART、SD/MMC 主机控制器和 TWAITM控制器(兼容CAN 2.0B)。 站在定位为边缘AI和便携设备的MCU的角度,相对来说其需求会更聚焦为“...
无需使用输入耦合电容,通过CTRL管脚检测一线脉冲选择内部输入高通滤波器的转折点以匹配不同喇叭。layout时无需精心考虑音频功放的布局以及走线,外围更简洁,调试更方便。 NS4168其独特的防失真功能可以有效防止输入信号过载、电池电压下降导致的输出信号失真,同时可以有效保护在大功率输出时扬声器不被损坏。 NS4168采用高效...

Most of the I/O pins on the ESP32-H2-MINI-1/1U module are broken out to the pin headers on both sides of this board for easy interfacing. Developers can either connect peripherals with jumper wires or mount ESP32-H2-DevKitM-1 on a breadboard.ESP32-H2-DevKitM-1 (with ESP32-H2-...
