Re: ESP32-S3-WROOM-1,IO0 AND IO47 PUII-UP?Why voltage unusual

At first, I didn't believe it, and I also suspected that there was a problem with the measurement. However, before I suspected it, many modules of my ESP32-S3 were already broken. After pulling up, the voltage level was only about 2V, and the code was judged to be low. It was because the pins were a...

ESP32-S3-WROOM-1,IO0 AND IO47 PUII-UP?Why voltage unusual

I made a product using ESP32-S3-WROOM-1 and put it into mass use. After working continuously for about a month when powered on, I found the following problem: the product uses IO0 (pin 27 of the module) and IO47 (pin 24 of the module) each connected in series with a 330R resistor, and the external w...

ESP32-S3-WROOM 模组引脚IO0,IO47内部上拉电平问题

去年使用ESP32-S3-WROOM-1做了个产品,并批量投入使用,上电连续工作一个月左右时间发现如下问题:产品中使用IO0(模组的27脚)和IO47(模组的24脚)各自串联330R电阻后,外接排线引出到小板子上按钮做用户输入用,程序配置为内部上拉,排线处每个IO放置了静电保护管SM05。当然还有其他引脚也有串联电阻后排线引出按钮输入,只是目前仅仅发现这两个IO有问题,问题现象是工作第一段时候后,明明没有按钮按下,程序却检测按钮按下了,通过万用表测量引脚的电压在2.5V以下,有的板子甚至引脚电压已经低至1.8V左右。也有的板子上拉电压是3.9V(确定没看错,我板子供电电压是3.3V)。更换新的...

Re: why usb-jtag disconnect when wifi start?

going on... if found wifi start appication download to board and run, usb device will change to "unknow device" in computer system,normal usb-jtag working is "USB JTAG debug unit " in computer system. it looks usb-jtag function is disabled by application! Now,how i debug the board? Where config to u...
