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 ...
BBFuino come with the ATmega328 controller, loaded with Optiboot (Arduino UNO's bootloader), compatible with Arduino IDE and sample code, design to fit breadboard for prototyping and learning, lower down the cost by taking out the USB to UART IC, so the board has the basic component to operate.

This profile is used to allow car hands-free kits to communicate with mobile phones in the car. It commonly uses Synchronous Connection Oriented link to carry a monaural audio channel with continuously variable slope delta modulation or pulse-code modulation, and with logarithmic a-law or μ-law quantization.
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 ...
The basic concept of the third state, high impedance (Hi-Z), is to effectively remove the device's influence from the rest of the circuit. If more than one device is electrically connected to another device, putting an output into the Hi-Z state is often used to prevent short circuits, or one device driving high (logical 1) against another device driving low (logical 0).
UVB-76 (Russian: УВБ-76; see § Name and callsigns for other callsigns), also known by the nickname "The Buzzer", is a shortwave radio station that broadcasts in Upper Side Band mode on the frequency of 4625 kHz.
The control panel for a building that has elements of automation The T-Com-Haus in Berlin, Germany was designed to demonstrate state-of-the-art home automation. A display at Computex 2008 showing a home automation system and embedded boards
In June 2023, Arduino released two new flavors of the Uno; R4 Minima and R4 Wifi. These mark a departure from previous boards as they use Renesas RA4M1 ARM Cortex M4 microcontroller, and the R4 Wifi a Espressif ESP32-S3-MINI co-processor. These versions are form factor, pin and power compatible with version R1 to R3, so should be largely be ...
