Comparison of Sleep Currents for XIAO ESP32C6, S3, and C3

Now that I have three different XIAO ESP32s (C3, S3, and C6), compared their sleep currents. I hope this will be helpful when considering low-power applications. First, I analyzed the schematic and datasheet as a reference. A 3.3V analog regulator XC6210 is used in C3, and this regulator’s quiescent current of 35uA accounts for most of the C3 sleep current. However, a diode NSR0520 is used, which has low reverse current, giving it an advantage in this area compared to S3 and C6. The power sup…
