ESP32 Integrated with traditional Bluetooth,low power Bluetooth and Wi-Fi,widely used: Wi-Fi support for a wide range if communication links,and support for direct connection to Internet using a router; Bluetooth allows users to connect to the phone or broadcast for signal detection. HLK-ESP32 supported data transmission rate is as high as 150Mbps, after the power amplifier and antenna, the output power can reach 20.5DBM, which can realize the maximum rang of wireless communication. ESP32 operating system is freeRTOS with LwIP, and TLS 1.2 with hardware acceleration is built in.The chip also supports OTA encryption upgrades, developers can continue to upgrade after product announced.
The ESP32-D0WDQ6 includes two low-power Xtensa® 32-bit LX6 MCUs. On-chip storage includes: •448-kB ROM for program startup and kernel function calls. •520 kB on-chip SRAM for data and instruction storage (including 8 kB RTC flash memory). – RTC flash memory, 8 kB SRAM, can be used for data storage and access by the main CPU during RTC startup in Deep-sleep mode. • RTC slow memory, 8 kB SRAM, accessible by coprocessor in Deep-sleep mode. •1 kbit eFuse with 256 bits for system-specific (MAC address and chipset); the remaining 768 bits. Reserved for user programs, these programs include Flash encryption and chip ID.
