SparkFun's popular Arduino-compatible Pro Micro development board has received something of a refresh, and the latest revision cuts the complexity by combining 5V and 3.3V operation on a single board while adding a Qwiic connector to the rear and USB Type-C to the front.
"Here at SparkFun, we refuse to leave 'good enough' alone — that's why we're adding to our lineup of Arduino-compatible microcontrollers," writes SparkFun's Xtopher of the new launch. "The SparkFun Qwiic Pro Micro is a revision of the original Pro Micro and is overall functionally the same as the previous version.
"The board is the same size as the original Pro Micro, but we added a few additional features by shrinking down some components on the board, such as a reset button, Qwiic connector, USB-C and castellated pads (this makes it really handy for you custom keyboard creators out there)! Think the Pro Mini except with an ATmega32U4 on board and full USB functionality."
As with its predecessor, the Qwiic Pro Micro includes full compatibility with the Arduino IDE and offers nine 10-bit analog-to-digital converter (ADC) pins and 12 general-purpose input/output (GPIO) pins — of which five are capable of pulse-width modulation (PWM).
The new pin format means the Qwiic Pro Micro can be soldered with male or female 2.54mm headers for breadboard or jumper wire user, while the castellated edges allow it to be surface mounted using standard hobbyist equipment.
The Qwiic Pro Micro is now available, priced at $19.95 before volume discount, from the SparkFun web shop — a slight premium over the $17.95 of the original Pro Micro's 3.3V and 5V models.
