The following table shows the current consumption of the ESP32 and ESP32-S2 in the different power modes. Click here to read this knowledge article in our Zebra Support Community. This function is very useful when your project does not allow to enter the deep-sleep mode because the ESP32-S2 can hold the WiFi connection to the router. Modify or disable sleep settings in Android.

Moreover the ESP32-S2 is able to turn off the WiFi transceiver when not in use to save more power but the WiFi is still enabled.

The ULP co-processor is active when the CPU is disabled in sleep-modes and consumes a lot less power then the CPU. The second generation, called ESP32-S2 was released in 2019 and has a fast single core microcontroller build in, the Xtensa single-core 32-bit LX7 and also a much more powerful co-processor.īecause the ESP32-S2 co-processor is based on the RISC-V architecture, the power consumption is much lower. If the single core is active, the clock frequency is 160 MHz and if the ESP32 runs in dual-code mode, the clock frequency is 240 MHz. The first generation of ESP32 microcontroller was released in 2016 by Espressif that use the Xtensa single/dual-core 32-bit LX6 microcontroller.
