Description

♥ESP32-WROOM-32 development board is a general-purpose Wi-Fi+BT+BLE MCU module, powerful and versatile, which can be used for low-power sensor networks and demanding tasks, such as speech coding, audio Streaming, MP3 decoding, etc. ♥The core of this module is the ESP32-DOWDQ6 chip, two Xtensa 32-bit LX6 CPU cores can be controlled independently, and the computing power is up to 600 MIPS. ♥The adjustment range of clock frequency is 80 MHz to 240 MHz, 448 KB ROM 520 KB SRAM 16 KB RTC SRAM
♥ESP32 module integrates 4MB QSPI Flash and integrates a wealth of peripherals, including capacitive touch sensor, Hall sensor, low noise sense amplifier, SD card interface, Ethernet interface, high-speed SDIO/SPI, UART, 12S and 12C, etc. The user can cut off the power of the CPU, and use the low-power coprocessor to continuously monitor whether the state changes of the peripherals or whether some analog quantities exceed the threshold.
♥Wi-Fi main features: 802.11 b/g/n 802.11 n (2.4 GHz) speeds up to 150Mbps Wireless Multimedia (WMM) Frame aggregation (TX/RX A-MPDU, RX A-MSDU) Immediate Block ACK (Immediate Block ACK) Defragmentation Beacon automatic monitoring (hardware TSF) 4 X virtual Wi-Fi ports Supports both Infrastructure BSS Station Mode/SoftAP Mode/Promiscuous Mode Please note that when the ESP32 scans in Station mode, the SoftAP channel will change at the same time Antenna diversity
♥Bluetooth main features: Bluetooth v4.2 complete standard, including traditional Bluetooth (BR/EDR) and Bluetooth Low Energy (BLE) Supports standard Class-1, Class-2, and Class-3 without the need for an external power amplifier Output power up to +12 dBm NZIF receiver has -97 dBm BLE receive sensitivity Standard HCI high-speed UART HCI based on SDIO/SPI/UART interface, up to 4 Mbps Support Bluetooth 4.2 BR/EDR and BLE dual mode controller CVSD and SBC audio codec algorithms
♥Security mechanism: Secure Boot flash encryption 1024-bit OTP, user available up to 768 bit Cryptographic hardware accelerators: AES/Hash (SHA-2)/RSA/ECC/Random Number Generator (RNG) ♥ Passed RF certification and software protocol certification
