HEXABITZ Moudule Micro USB-B to UART Converter

H1AR3x is a Micro USB-B-to-UART bridge module based on FTDI FT230XQ-R and STM32F0 MCU. It provides both power and communication through a virtual COM port.

Use this module to add USB 2.0 type-Micro-B serial ports to your Hexabitz arrays or other projects.
You can power your array from the USB port as well. USB power can be easily disabled via a jumper.
You can easily connect the USB port to any of module array (UART) ports, or even do advance multiplexing using DMAs and software tricks.
