The SD card module provides the micro memory card interface and it is connected to ESP32 via SPI port.
These days SD cards are available with 4GB to 128GB memory size. Secure Digital Card, abbreviated as SD Card is a non-volatile memory card, commonly used to write and read large quantities of data in smart devices. It supports wake up from GPIO / Sensor interrupts, timers and 5uA deep sleep current consumption.
The ESP32 supports all IEEE 802.11 standard security feature (WFA, WPA/WPA2 and WAPI), and cryptographic hardware acceleration (AES, RSA, SHA-2, ECC, RNG etc). The ESP32 provides peripheral interfaces like ADC, DAC, touch sensors, SPI, I2C, I2S, UART, CAN, PWM etc. The ESP32 is constructed with Xtensa dual-core (or single-core) 32-bit RISC architecture, operating at 160MHz or 240MHz, with up to 520KiB internal SRAM, integrated with Wi-Fi (802.11 b/g/n) and Bluetooth (v4.2 BR/EDR and BLE (shares the radio with Wi-Fi).
