Firmware can configure register bits to change the settings of ”VDD_SDIO Voltage”. 2. Internal pull-up resistor (R1) for IO45 is not populated in the module, as the flash and SRAM in ESP32-S2-WROVER work at 3.3 V by default (output by VDD_SPI). Please make sure IO45 will not be pulled high when the module is powered up by external circuit.
