Saelig's Micro-USB is made for connecting micros or circuits to USB, offering baud rates up to 1Mbps. The 0.7 x 0.5-inch device only needs eight pads on the target board in a 0.1-inch grid. It connects to a standard PC using a regular USB cable, and royalty-free drivers for major operating systems are available. It only needs ground, RX and TX signals, and works from -40 to 85C. A USB-serial interface allows USB to RS-232 and USB to RS-422/RS-485 converters, ideal for making legacy RS232 upgrades, PDA and cell phone USB interface cables, bar code readers, POS terminals, and other applications.
University of Southampton researchers have come up with a way to 3D print transparent optical fibers like those used in fiber-optic telecommunications cables, potentially boosting frequency and reducing loss.
