I have connected an ESP PSRAM64H chip to an ESP32 WROOM board (38 pin, with SPI1 pins exposed (GPIO6, 7, 8, 9, 10)) following the same pin connections as for ESP32 WROVER B, as shown in the schematic below: PSRAM64HCOnnectedToESP32WROOM.jpg I have setup the board parameters ...
My question is this: I have six of these great 30-pin mcu's and the blue LED's all behave differently. For instance, some mcu's will light these blue LED's when there is absolutely NO code reference to GPIO2. If I set - Code: Select all digitalWrite (blu_led, LOW) in setup(...
Although you can define the pins properties on the software, there are pins assigned by default as shown in the following figure (this is an example for theESP32 DEVKIT V1 DOIT boardwith 36 pins – the pin location can change depending on the manufacturer). Additionally, there are pins wit...
In the pinout diagram above, you can see which pins support RTC. Hall Sensor Pin The ESP32 features a Hall sensor, making it suitable for applications requiring proximity or magnetic field detection. The hall sensor is hidden behind the metal lif of the ESP32. The hall sensor pin, however...

remains the same across all development boards. You can define the pins the same way in firmware also. The following picture shows the pinout diagram of the ESP32 DEVKIT V1 DOIT board. In your version of the ESP32 development kit, each GPIO pin may be exposed on a different pin number....
