1. Introduction In the ecosystem of embedded systems, IoT development, and legacy hardware interfacing, the USB-to-UART bridge is an indispensable tool. Among the myriad of chips from Silicon Labs (CP210x), FTDI (FT232), and Prolific (PL2303), the MA112 occupies a specific niche. Often found on low-cost development boards, GPS modules, and industrial sensor interfaces, the MA112 is a highly integrated bridge chip designed for simplicity and cross-platform compatibility.
