SparkFun RedBoard Plus

• SparkFun RedBoard Plus
• Offers an Arduino-compatible development board
• Includes a 3.3 V voltage translator
• Programmed over a USB-C cable
• Qwiic compatible
• Doesn’t require soldering

The SparkFun RedBoard Plus is an Arduino-compatible development board that has everything you need in an Arduino Uno with many extra perks.
The best part about the RedBoard Plus is that it utilizes the handy Qwiic Connect System which means no soldering or shields are required to connect it to the rest of your system.

The SparkFun RedBoard Plus has all of the hardware peripherals you know and love: 22x Digital I/O pins with 6x PWM pins, 8x analog pins, UART, I2C, SPI, and external interrupts.

The power portion of the RedBoard Plus has been optimized: uses AP2112 3.3 V voltage regulator to provide up to 600 mA to daisy chain multiple Qwiic boards and sensors, with full thermal and reverse circuit protection, and added extra decoupling capacitance to increase the sensitivity of the ADC readings.
