It is a Wifi Bluetooth Combo Module with ESP32-D0WDQ6 chip, named Goouuu-ESP32.
Compare with NodeMCU with ESP8266 WiFI module.
ESP32 is a low-cost, low-power system on a chip (SoC) series with Wi-Fi & dual-mode Bluetooth capabilities! The ESP32 series of chips presently includes ESP32-D0WDQ6 (and ESP32-D0WD), ESP32-D2WD, and ESP32-S0WD. At its heart, there's a dual-core (or single-core) Tensilica Xtensa LX6 microprocessor with a clock rate of up to 240 MHz. ESP32 is highly integrated with built-in antenna switches, RF balun, power amplifier, low-noise receive amplifier, filters, and power management modules. Engineered for mobile devices, wearable electronics, and IoT applications, ESP32 achieves ultra-low power consumption through power saving features including fine resolution clock gating, multiple power modes, and dynamic power scaling. ~ know more: http://esp32.net/
