Wiki: ESP 32

Aliased from TinyPico, TinyPicoNano and FeatherS2

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.
