The ESP32 has three hardware UARTs: UART0, UART1 and UART2. They each have default GPIO assigned to them, however depending on your ESP32 variant and board, these pins may conflict with embedded flash, onboard
Pins HIGH at Boot 一些GPIO在启动或重置时将其状态更改为高或输出PWM信号。这意味着,如果输出连接到这些gpio,则在ESP32重置或引导时可能会得到意外的结果。 GPIO 1 GPIO 3 GPIO 5 GPIO 6 to GPIO 11 (connected to the ESP32 integrated SPI flash memory – not recommended to use). GPIO 14 GPIO 15 ...

注:ESP32不做人脸识别,则安装2.0.7; 做人脸识别安装1.0.6(2.0版库开始不支持人脸识别)2.安装完硬件库后检查开发板库的位置自动前往在地址栏粘贴%LOCALAPPDATA%/Arduino15/packages/esp32/hardware/esp32并回车 亦可手动点击文件夹C:\用户\用户名\AppData\Local\Arduino15\packages\esp32\hardware\esp32注:用户...
FCC ID: 2AJMTLOPY1R Documentation (datasheet, pinout) Do not connect anything to pins P5, P6 and P7, since these pins are used by the SPI bus that controls the LoRa radio. These pins should be treated as NC (No Connection). Wiring connections to these pins will cause incorrect behavior...
In order to use ADC2 for other functions, we have to acquire complicated firmware locks and very difficult to do So, it's not advisable to use ADC2 with WiFi/BlueTooth (BT/BLE). Use ADC1, and pins GPIO32-GPIO39 If somehow it's a must to use those pins serviced by ADC2 (GPIO0, ...

Based on the datasheet, I should not be able to work with those pins which is true when I use the devkit, but somehow when using the module on a pcb, the pins are available. Thanks Last edited by msh911 on Fri Jun 21, 2024 7:08 am, edited 1 time in total. ...
Caution! May be inappropriate use of GPIO37. ESP32S3 GPIO restrictions : Strapping pin: GPIO0, GPIO3, GPIO45 and GPIO46 are strapping pins. SPI0/1: GPIO26-32 are usually used for SPI flash and PSRAM and not recommended for other uses. When using Octal Flash or Octal PSRAM or both,...
