Description:

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. We've also broken out the SDA, SCL and IOREF pins that showed up on the Arduino Uno R3 footprint, so the RedBoard Plus is compatible with future shields (if you choose to use them). Two additional analog pins are included for A6 and A7.

The USB-to-serial is now done with a reversible USB-C connector with through hole anchoring and the ubiquitous CH340G requiring fewer driver installs. The power portion of the RedBoard Plus has been optimized: we use the AP2112 3.3V voltage regulator to provide up to 600mA 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. We've also increased the PTC from 500mA to 2A.
