According to Wikipedia's ESP32 page:
ESP32 is a series of low-cost, low-power
system on a chip microcontrollers with integrated
Wi-Fi and dual-mode
Bluetooth . The ESP32 series employs a
Tensilica Xtensa LX6 microprocessor in both dual-core and
single-core variations and includes built-in antenna switches, RF
balun , power amplifier, low-noise receive amplifier, filters, and power-management modules. ESP32 is created and developed by
Espressif Systems , a Shanghai-based Chinese company, and is manufactured by
TSMC using their 40 nm process.
[2] It is a successor to the
ESP8266 microcontroller.
Recently the ESP32 has been featured in a series of Single Board Computers (SBC) designed by Seon Rosenblum of Unexpected Maker, in the "Nano" (13x27mm), "Tiny" (18x32mm and 18x35mm) and "Feather" (23x51mm) form factors. These boards all have WiFi and support CircuitPython and MicroPython. The TinyPico boards are available with either USB Micro-B or USB-C power connectors.
