The ESP32-WROVER is a WiFi and Bluetooth module using the popular ESPRESSIF ESP32 chip. The pads on the module have a 1.27mm.
This is the latest V4 module, with an IPEX(U.FL) Antenna Connector. It is also available with a PCB antenna!
This module is a slightly larger version of the ESP-WROOM-32, with the addition of 32 Mbits (4 MByte) RAM (SPI Pseudo static PSRAM). The top (closest to the antenna) 14 pads on ether side are pin and footprint compatible with the ESP-WROOM-32 module.
Note that GPIO16 and GPIO17 are NOT available on the ESP32-WROVER! They are used for the external PSRAM chip.
The ESP32 chip integrates a dual-core processor with 448 KByte ROM, 520 KByte SRAM, 16 KByte SRAM in RTC, 802.11 b/g/n/e/I Wi-Fi, Bluetooth v4.2 BR/EDR & BLE, clocks & Times, abundant peripheral Interfaces and sercurity mechanism.
Software can be developed using many different platforms, including Arduino. It is designed for Generic low power IoT sensor hub, loggers, video steaming for camera, Wi-Fi & Bluetooth enabled devices, Home automation and mesh network applications, aimed at makers, hardware engineers, software engineers and solution provides.
The ESP32 is the most integrated solution for Wi-Fi + Bluetooth applications in the industry with less than 10 external components. ESP32 integrates the antenna switch, RF balun, power amplifier, low noise receive amplifier, filters, and power management modules. As such, the entire solution occupies minimal Printed Circuit Board (PCB) area.
