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 ...
They did this with the introduction of Boards Manager and the Arduino SAM Boards Core. A "core" is the collection of software components required by Boards Manager and the Arduino IDE to compile an Arduino C/C++ source file down to the target MCU's machine language.
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. Most Arduino-compatible boards require an additional shield for these resources. NB2A [192]
A "core" is the collection of software components required by the Board Manager and the Arduino IDE to compile an Arduino C/C++ source file for the target MCU's machine language. Some ESP8266 enthusiasts developed an Arduino core for the ESP8266 WiFi SoC, popularly called the "ESP8266 Core for the Arduino IDE". [ 18 ]

The U.S. Postal Service, which has lost more than $100 billion since 2007, reported a net loss of $9.5 billion for its fiscal year ending Sept. 30, $3 billion more than last year, largely due to a ...
The ports supported in the mainline are ARM Cortex-M (many STM32 [8] boards, RP2040 boards, TI CC3200/WiPy, Teensy boards, Nordic nRF series, SAMD21 and SAMD51), ESP8266, ESP32, [9] 16-bit PIC, Unix, Windows, Zephyr, and JavaScript. [10] Also, there are many forks for a variety of systems and hardware platforms not supported in the mainline. [11]
