there isn’t a specific “XIAO” ESP32C3 or XIAO SAMD2. However, I can provide you with some general information about ADC operating voltage for commonly used microcontrollers.
- ESP32C3:
- The ADC operating voltage for ESP32C3 is typically 0 to 3.3V. It is important to note that exceeding this voltage may damage the ADC input.
- SAMD21 (XIAO SAMD21):
- The SAMD21 operates at 3.3V. Therefore, the ADC reference voltage is usually 3.3V. The ADC can handle input voltages in the range of 0 to 3.3V.
- RP2040 (XIAO RP2040):
- The RP2040 operates at 3.3V. The ADC reference voltage is typically 3.3V, and the ADC can handle input voltages in the range of 0 to 3.3V.
- nRF52840 (XIAO nRF52840):
- The nRF52840 operates at 3.3V. The ADC reference voltage is usually 3.3V, and the ADC can handle input voltages in the range of 0 to 3.3V.
