SparkFun SparkX BlackBoard C

SparkFun SparkX BlackBoard C offers all the features of the standard Arduino Uno Microcontroller Board, but adds a variety of additions for advanced applications. Like the Arduino Uno, the BlackBoard C is based on the ATmega328P MCU, with 14 digital I/O pins for PWM, analog inputs, UART, SPI, and external interrupt. The BlackBoard C, however, features a reversible USB-C connector, an updated voltage regulator that provides up to 600mA with full thermal and reverse circuit protection, and added extra decoupling capacitance to increase the sensitivity of the ADC readings. A Qwiic connector on the edge of the BlackBoard C allows for quick and seamless connection to the Qwiic ecosystem of I²C sensors, actuators, and shields.
