ATmega328P Uno R3 Board Products

Description

The Arduino Uno R3 is a microcontroller board based on the ATmega328P MCUMicrocontroller Unit. This board is useful for prototyping with a form factor and layout that is convenient to interface with when plugging in power and I/OInput/Output. The large amount of documentation, guides, and tutorials, makes this a good board to start with when learning about microcontrollers.

More details on the board layout, different ways of powering the board, and I/OInput/Output are covered in the Arduino Uno R3 Hardware Overview.

SparkFun DEV-18158 RedBoard Plus ATMega328P

Package includes:

• 1x RedBoard Plus

+ About this item:

• ATmega328 16MHz microcontroller, 32KB flash and 2KB RAM, with Optiboot (UNO) Bootloader.
• Rev3 shield compatible.
• Interface: 22x I/O pins with 6x PWM pins, 8x Analog Inputs, 1x UART, 1x I2C, 1x SPI, and external interrupts, Qwiic connector, USB-C connector with CH340C Serial-USB converter IC
• Bypass Jumper: the board includes a jumper to bypass the resettable fuse.
• I/O Logic Switch: Instead of cutting a jumper pad and adding solder to the board, you can now flip the switch to adjust the logic level for the system voltage.
• Two More Analog Pins: Two additional analog pins are included for A6 and A7. Previous designs of the Uno R3 footprint on the RedBoard did not include the pins. These analog pins are included by the power pins as PTH pads.
• PTH Pads: All of the edge pins on the RedBoard Plus now include an additional pin through hole (PTH) pad by each female header. This makes the board slightly wider but you have the advantage of soldering wires or additional header pins to the board.
• Voltage Supply: 5V power over USB or through the barrel jack 7V to 15V DC (AP2112 Voltage Regulator). Includes 3.3V to 5V Voltage Level Jumper.
