A new version of our popular Pro Micro board is now available with new upgrades.
Welcome, welcome, welcome, everyone! We may not have too many products to show you this week but, as you know, that usually means we have something big. This week we are happy to announce a brand new version of our super small, Arduino-capable Pro Micro! We've added a handful of key new features to the board and have been able to combine the 5V version with the 3.3V version.
Here at SparkFun, we refuse to leave 'good enough' alone - that's why we're adding to our lineup of Arduino-compatible microcontrollers! 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.
The USB to Serial CH340E IC is a USB bus conversion chip - it can realize USB to UART interface, or USB to printer interface. In serial UART mode, CH340E provides common MODEM liaison signal, used to expand UART interface of computer or upgrade the common serial device to USB bus directly.
