2.4GHz Dual Mode WiFi+Bluetooth Development Board: Built in ESP32-S chip, Xtensa single core 32-bit LX7 microprocessor, supporting clock frequencies up to 240 MHz. 128 KB ROM, 320 KB SRAM, 16 KB RTC SRAM. The chip supports secondary development without the need for other microcontrollers or processors
Compatible With Arduino+LoRa: The ESP32 development board is 100% compatible with the Arduino IDE, Lua, and Micropython. It is easy to develop and supports the LWIP protocol, Freertos, and three modes: AP, STA, and AP+STA
Advanced Peripheral Interfaces & Sensors: SPI, I2S, UART, I2C, LED PWM, LCD interface, Camera interface, ADC, DAC, touch sensor, temperature sensor, and up to 43 GPIOs. In addition, this series of chips also includes a full-speed USB On The Go (OTG) interface, which can support USB communication
Ultra Low Power Coprocessor (ULP): ESP32-S series chips support multiple low-power operating states, meeting the power consumption requirements for various application scenarios. The precise clock gating, dynamic voltage clock frequency adjustment, and adjustable output power of RF power amplifiers unique to chips can balance communication distance, data rate, and power consumption best
Unique Hardware Security Mechanism: The hardware encryption accelerator supports AES, SHA, and RSA algorithms. RNG, HMAC, and Digital Signature modules provide more security performance. Other security features include flash encryption and secure boot signature verification. A comprehensive security mechanism enables the chip to meet strict security requirements
