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 ...
NodeMCU DEVKIT 1.0, bottom. NodeMCU is a low-cost open source IoT platform. [4] [5] It initially included firmware which runs on the ESP8266 Wi-Fi SoC from Espressif Systems, and hardware which was based on the ESP-12 module.
Added descriptive text to diagram's title for conveying what the ESP32 is (it's a Wi-Fi & Bluetooth microcontroller) for clarity. SVG file post-processed for file size reduction. 07:56, 3 September 2018
SparkFun ESP8266 Thing. The reason for the popularity of many of these boards over the earlier ESP-xx modules is the inclusion of an on-board USB-to-UART bridge (like the Silicon Labs' CP2102 or the WCH CH340G) and a Micro-USB connector, coupled with a 3.3-volt regulator to provide both power to the board and connectivity to the host (software development) computer – commonly referred to as ...
ESP32 – a series of low-cost, low-power system on a chip microcontrollers with integrated Wi-Fi and dual-mode Bluetooth. STM32 – a family of 32-bit microcontroller integrated circuits; Raspberry Pi – Raspberry Pi's series of small single board computers; Thumby (Game Console) – a thumb-sized micro-console powered by the RP2040
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.
