I've designed a board based on the ESP32-H2-MINI-1 module. The processor enters light sleep with a GPIO held high, and I'm noticing ~500mv drops for ~1ms which happen every few seconds. I'm guessing this is when the processor wakes up and is powering up the peripherals. I tested...
I am trying to program HC-SR04 Sensor to measure distance and send the measurements through LoRa. I have an ESP32-S3 board but since the sensor requires a 5V power supply to operate, I would need the expansion board since the ESP32-S3 board can only provide 3.3 output voltage. ...

DatanoiseTV changed the title Add MCLK output for ESP32 Add MCLK output for ESP32-S3 Dec 23, 2022 Owner earlephilhower commented Dec 23, 2022 Would you like to do a PR? You may need to add #ifdefs around things since the Espressif SDK seems to play with the I2S structs ...
I am looking to drive a relay module from my ESP32-CAM. The output used is GPIO 12 which goes to the signal input of the relay module. For the power supply to relay module, I am planning to use the VCC output pin of the ESP32-CAM. Please let me know the maximum current I can...
