1.PRODUCT DESCRIPTION
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 240 MHz. 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 (se-cure boot) signature
verification. The perfect security mechanism enables the chip to be perfectly applied to
various encryption products.
