M.2 Serial Communications
M.2 (the bus formerly known as NGFF) is a new, more flexible alternative to PCI Express Mini Cards (mPCIe) for use as a multi-purpose small-form-factor embedded computer expansion bus. Designed for versatility, M.2 supports both smaller and larger footprints than mPCIe, and consumes less power, making it a perfect choice for a variety of embedded applications.
Interworld Electronics offers a wide range of 1-4 port isolated RS-232 / 422 /485 boards as well as non isolated 2 and 4 port combo RS-232 , 422 and 485 boards.
