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.

WiFi coprocessor - 240 MHz Espressif ESP32-S3-MINI (IEEE802.11 b/g/n WiFi and Bluetooth 5 LE) and a 6-pin 3x2 2.54mm header for external programming. 12x8 LED matrix - it is driven by 11 GPIO pins using a charlieplexing scheme. Qwiic I²C connector. This 4-pin 1.00mm JST SH connector provides external connection to a 3.3 volt I²C bus. Don't ...
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 ...
In computer programming, instrumentation is the act of modifying software so that analysis can be performed on it. Generally, instrumentation either modifies source code or binary code. Instrumentation enables profiling: [1] measuring dynamic behavior during a test run.
A computer program is a sequence or set [a] of instructions in a programming language for a computer to execute. It is one component of software, which also includes documentation and other intangible components. [1] A computer program in its human-readable form is called source code.
Bell codes, buzzer codes or Communication Signal Appliance codes entail a series of bells or buzzers used on passenger trains for communication between the driver and ...
