This is a family of ESP32-based modules with some integrated key components, including a crystal oscillator and an antenna matching circuit. The modules constitute ready-made solutions for integration into final products. If combined with a few extra components, such as a programming interface, bootstrapping resistors, and pin headers, these modules can also be used for the evaluation of ESP32’s functionality.

FURTHER INFO
An ESP-WROOM-32 module with a Tensilica Xtensa Dual-Core 32-bit LX6 CPU is included on the development board. It has two CPU cores (each of which can be operated independently), a clock frequency of 80 to 240 MHz, and up to 600 DMIPS of performance (Dhrystone Million Instructions Per Second).
The ESP32 has an HT40 802.11b/g/n Wi-Fi transceiver, which allows it to not only connect to a WiFi network to access the Internet but also to build its own network to which other devices may join directly. The ESP32 also supports WiFi Direct, which is a good option for peer-to-peer connections that don’t require an access point. The chip is both Bluetooth 4.0 (BLE/Bluetooth Smart) and Bluetooth Classic (BT) compatible, making it even more flexible.
