ADC: On-chip 12-bit SAR (Successive Approximation Registers) ADCs (Analog to Digital Converter) which supports measurements on 16 channels of ESP32. DAC: On-chip two 8-bit DAC (Digital to Analog) channels to produce digital signals into analog voltage signal outputs. Both DAC channels can al...
Note that during use, it is important to ensure common grounding and not to exceed the measurement range. It is suitable for learning about the analog input of the ESP32-S3, allowing the reading of analog values from specific pins, observing changes, and testing stability Hardware connection ...
