ESP-12K is a Wi-Fi module developed by Ensink Technology. The core processor ESP32-S2 of this module is a highly integrated low-power Wi-Fi system-on-chip (SoC) designed for the Internet of Things (IoT) , Mobile devices, wearable electronic devices, smart home, and other applications. ESP32-S2 has industry-leading low-power performance and RF performance supports IEEE802.11b/g/n protocol, integrates Wi-Fi MAC, Wi-Fi RF and baseband, RF switch, RF Balun, power amplifier, low noise Amplifier, etc. The ESP32-S2 chip is equipped with Xtensa 32-bit LX7 single-core processor, and its operating frequency is up to 240MHz. The chip supports secondary development without the use of other microcontrollers or processors. The chip has 320 KB SRAM and 128 KB ROM and can be connected to flash and RAM through SPI / QSPI / OSPI and other interfaces. ESP32-S2 supports a variety of low-power operating states to meet the power consumption requirements of various application scenarios. The unique fine clock gating function, dynamic voltage clock frequency adjustment function, and RF output power adjustable function of the chip can achieve the best balance between communication distance, communication rate, and power consumption. ESP32-S2 provides a wealth of peripheral interfaces, including SPI, I2S, UART, I2C, LED PWM, LCD interface, Camera interface, ADC, DAC, touch sensor, temperature sensor and up to 43 GPIO. It supports the expansion of PSRAM on the periphery of the chip, and the ESP-12K module can be equipped with PSRAM. In addition, it includes a full-speed USB On-The-Go (OTG) interface that can support the use of USB communication. ESP32-S2 has a variety of unique hardware security mechanisms. The hardware encryption accelerator supports AES, SHA, and RSA algorithms. The RNG, HMAC and Digital Signature (Digital Signature) modules provide more security features. Other security features include flash encryption and secure boot (secure boot) signature verification. The perfect security mechanism enables the chip to be perfectly applied to various encryption products.
