Description
Brand: Espressif ESP32-WROVER and ESP32-WROVER-I ESP32-WROVER is a module based on the ESP32 chip, which is powerful and versatile. It can be used for low-power sensor networks and demanding tasks such as voice coding, audio streaming and MP3 decoding. The ESP32-WROVER use the esp32-D0WDQ6 chip same as the esp-wroom -32. In contrast, the ESP32-wrover module also has a 32-mbit SPI P-S-R-A-M. In this way, ESP32-wrover comes with 4 MB of SPI flash and 8 MB of P-S-R-A-M. ESP32-WROVER USES the PCB board antenna, and the other model, ESP32- WROVER - I, USES the IPEX antenna.
