ESP32-WROVER

ESP32-WROVER

Module ESP32-WROVER WiFi Bluetooth là một module tích hợp chip ESP32-D0WDQ6 của Espressif Systems cho các ứng dụng WiFi, Bluetooth Low Enegry.

Module được hỗ trợ SDK Firmware từ hãng và rất thích hợp cho việc phát triển các dự án mã nguồn mở.

ESP32-WROVER về cơ bản giống với chip ESPWROOM-32 nhưng ESP32-WROVER có hỗ trợ thêm PSRAM 32 bit (SPI Pseudo static RAM). Như vậy ESP32-WROVER có 4MB SPI flash và cả 4MB PSRAM ngoài.
