According to Wikipedia's [ESP32|https://en.wikipedia.org/wiki/ESP32] page: %%blockquote __ESP32__ is a series of low-cost, low-power [system on a chip|https://en.wikipedia.org/wiki/System_on_a_chip] [microcontrollers|https://en.wikipedia.org/wiki/Microcontroller] with integrated [Wi-Fi|https://en.wikipedia.org/wiki/Wi-Fi] and dual-mode [Bluetooth|https://en.wikipedia.org/wiki/Bluetooth] . The ESP32 series employs a [Tensilica|https://en.wikipedia.org/wiki/Tensilica] Xtensa LX6 microprocessor in both dual-core and [single-core|https://en.wikipedia.org/wiki/Single-core] variations and includes built-in antenna switches, RF [balun|https://en.wikipedia.org/wiki/Balun] , power amplifier, low-noise receive amplifier, filters, and power-management modules. ESP32 is created and developed by [Espressif Systems|https://en.wikipedia.org/w/index.php?title=Espressif_Systems&action=edit&redlink=1] , a Shanghai-based Chinese company, and is manufactured by [TSMC|https://en.wikipedia.org/wiki/TSMC] using their 40 nm process.%%sup [[2]/% It is a successor to the [ESP8266|https://en.wikipedia.org/wiki/ESP8266] microcontroller. %% Recently the ESP32 has been featured in a series of Single Board Computers (SBC) designed by Seon Rosenblum of [Unexpected Maker|https://unexpectedmaker.com/], 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. !!! TinyPico NANO !
