Wireless connectivity
Wi-Fi: 150.0 Mbps data rate with HT40
Bluetooth: BLE (Bluetooth Low Energy), Bluetooth Classic, and Web BLE
Processor: Tensilica Xtensa Dual-Core 32-bit LX6 microprocessor, running at 160 or 240 MHz
ROM: 448 KB
SRAM: 520 KB
Low Power: ensures that you can still use ADC conversions, for example, during deep sleep.
Peripheral Input/Output:
Peripheral interface with DMA that includes capacitive touch
ADCs (Analog-to-Digital Converter)
DACs (Digital-to-Analog Converter)
I²C (Inter-Integrated Circuit) – I2C Communication Between Two ESP32
UART (Universal Asynchronous Receiver/Transmitter)
SPI (Serial Peripheral Interface)
I²S (Integrated Interchip Sound)
RMII (Reduced Media-Independent Interface)
PWM (Pulse-Width Modulation).
Security: hardware accelerators for AES and SSL/TLS
USB Drivers: CP210x (Windows PC or Mac OS X)
Arduino IDE compatible: you can program the ESP32 with the Arduino IDE 2
