ESP32-WROVER 모듈 -PCB 안테나
(ESP32-Wrover)
개요
- 본 제품은 ESP32-Wrover 모듈입니다.
- WiFi-BT-BLE 모듈로 다양한 어플리케이션에 사용이 가능한 모듈입니다.
- 이 칩의 코어는 ESP32-D0WDQ6로 ESP-WROOM-32모듈과 동일합니다.
- ESP-WROOM-32과 비교하여 ESP32-WROVER는 추가적인 SPI Pseduo static RAM (PSRAM) 32Mbit를 지원합니다.
- PCB 안테나가 장착되어 있습니다.
특징
- ESP32-WROVER is a powerful, generic WiFi-BT-BLE MCU module that targets a wide variety of applications,ranging from low-power sensor networks to the most demanding tasks, such as voice encoding, music streamingand MP3 decoding.
- At the core of this module is the ESP32-D0WDQ6 chip*, same as ESP-WROOM-32 module. Compared to ESPWROOM-32,ESP32-WROVER has an additional SPI Pseudo static RAM (PSRAM) of 32 Mbits. As such, ESP32-WROVER features both 4 MB external SPI flash and 4 MB external PSRAM.
- The ESP32-WROVER module has a PCB antenna, while the ESP32-WROVER-I uses an IPEX antenna. The information in this datasheet is applicable to both of the two modules.
- The chip embedded is designed to be scalable and adaptive. There are two CPU cores that can be individually controlled, and the clock frequency is adjustable from 80 MHz to 240 MHz. The user may also power off the CPU and make use of the low-power co-processor to constantly monitor the peripherals for changes or crossing of thresholds. ESP32 integrates a rich set of peripherals, ranging from capacitive touch sensors, Hall sensors, low-noise sense amplifiers, SD card interface, Ethernet, high-speed SPI, UART, I2S and I2C.
- The integration of Bluetooth, Bluetooth LE and Wi-Fi ensures that a wide range of applications can be targeted,and that the module is future proof: using Wi-Fi allows a large physical range and direct connection to the internet through a Wi-Fi router, while using Bluetooth allows the user to conveniently connect to the phone or broadcast low energy beacons for its detection.
- The sleep current of the ESP32 chip is less than 5 µA, making it suitable for battery powered and wearable electronics applications. ESP32 supports a data rate of up to 150 Mbps, and 20.5 dBm output power at the antenna to ensure the widest physical range. As such the chip does offer industry-leading specifications and the best performance for electronic integration, range, power consumption,and connectivity.
- The operating system chosen for ESP32 is freeRTOS with LwIP; TLS 1.2 with hardware acceleration is built in as well. Secure (encrypted) over the air (OTA) upgrade is also supported, so that developers can continually upgrade their products even after their release.
