SparkFun Qwiic Pro Micro USB-C (ATmega32U4)
SparkFun Qwiic Pro Micro USB-C (ATmega32U4) offers nine channels of 10-bit ADC, five PWM pins, 12 DIOs, and hardware serial connections Rx/Tx. The DEV-15795 Qwiic Pro Micro is an Arduino-compatible board and part of the SparkFun Qwiic Connect System. The SparkFun Qwiic Connect System is an ecosystem of I2C sensors, actuators, shields, and cables that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector.
The Qwiic Pro Micro USB-C is a revision of the original Pro Micro with smaller components, such as the reset button, Qwiic connector, USB-C, and castellated pads. The benefit of the reset button is to quickly reset the board or place it into bootloader mode, without the need to take out a piece of the jumper wire. The DEV-15795 Board has a voltage regulator on board that accepts voltage up to 6VDC. The device provides the 5V/16MHz ATmega32U4 on board and has full USB functionality.
The Qwiic Pro Micro USB-C through-hole pads have castellated edges for each pin. This adds a lower profile allowing the board to be built into another assembly during production. A Qwiic connector is populated on the bottom of the board to easily add Qwiic enabled I2C devices to designs.
