Arduino UNO is a microcontroller board based on the ATmega328P. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz ceramic resonator, a USB connection, a power jack, an ICSP header and a reset button.
Arduino UNO is a microcontroller board based on the ATmega328P (datasheet). It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz ceramic resonator (CSTCE16M0V53-R0), a USB connection, a power jack, an ICSP header and a reset button.
Arduino UNO SMD is a microcontroller board based on the ATmega328P. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz ceramic resonator, a USB connection, a power jack, an ICSP header and a reset button.
The UNO Q is equipped with two connector types: the classic UNO-style headers on the top, designed for prototyping and debugging, guaranteeing full compatibility with Arduino UNO Shields, and the high-speed header connectors on the bottom, purpose-built for integration with UNO Q carriers.
In addition to the specific functions listed below, the digital pins on an Arduino board can be used for general purpose input and output via the pinMode (), digitalRead (), and digitalWrite () commands.
The Arduino® UNO R3 is the perfect board to get familiar with electronics and coding. This versatile development board is equipped with the well-known ATmega328P and the ATMega 16U2 Processor.
The UNO R4 Minima features a microcontroller based on the Renesas RA4M1 (Arm® Cortex®-M4) with an operating voltage of 5 V. It has 14 digital I/O, 6 analog inputs with up to 14-bit resolution, a clock speed of 48 MHz, and 32 kB SRAM, 256 kB flash memory & 8 kB of EEPROM.
Below you can find the pinout for the Arduino UNO R4 Minima. All UNO boards largely share the placement of many pins, to make it easy for accessories to be designed for different UNO boards but if you create accessories for an older UNO be sure to check its respective pinout.
In this section, we will explore some of the technical aspects of the UNO Mini LE, such as pinout, datasheet, schematics and external power sources. These are also available from the official documentation for the UNO Mini LE board.
Arduino boards to share information with each other. In this example, two boards are programmed to communicate with one another in a Controller Reader/Peripheral Sender configuration via the I2C synchronous serial protocol.
