ESP32 is a series of low-cost, low-power system-on-chip microcontrollers with integrated Wi-Fi and dual-mode Bluetooth.The ESP32 series employs either a Tensilica Xtensa LX6 microprocessor in both dual-core and single-core variations, an Xtensa LX7 dual-core microprocessor, or a single-core RISC-V microprocessor and includes built-in antenna switches, RF balun, power amplifier, low-noise ...
There is a GPS-only version, a combined GPS/GLONASS version, and a GPS/Beidou version. An adaptor board adds a JST connector for a lithium-ion battery, a charger for the battery, and a microSD card slot connected to the SPI pins. NB1A [191] An Arduino-compatible board that includes a battery backed up real-time clock and a four channel DAC.

NodeMCU was created shortly after the ESP8266 came out. On December 30, 2013, Espressif Systems [6] began production of the ESP8266. [12] NodeMCU started on 13 Oct 2014, when Hong committed the first file of nodemcu-firmware to GitHub. [13]
The BPI Bit (also referred to as BPI:bit, stylised as webduino:bit) is an ESP32 with Xtensa 32bit LX6 single/dual-core processor based embedded system. The board is 5 cm × 5 cm and has an ESP32 module with Xtensa 32bit LX6 single/dual-core processor, with a capacity of up to 600DMIPS, with a built-in 448KB ROM and 520 KB SRAM accelerometer and magnetometer sensors, 2.4G WiFi, Bluetooth and ...
While Arm is a fabless semiconductor company (it does not manufacture or sell its own chips), it licenses the ARM architecture family design to a variety of companies. Those companies in turn sell billions of ARM-based chips per year—12 billion ARM-based chips shipped in 2014, [1] about 24 billion ARM-based chips shipped in 2020, [2] some of those are popular chips in their own right.
The following table compares official Arduino boards, and has a similar layout as a table in the Arduino Uno article. The table is split with dark bars into three high-level microcontroller groups: 8-bit AVR cores, 32-bit ARM Cortex-M cores, and 32-bit ESP32 microcontrollers.
