New Part Day: The Fifty Cent USB Chip

If you want to plug a USB cable into your next project, you’ve got a problem. USB is not UART, and UART is what every microcontroller serial port wants. To add USB to your microcontroller project, you’ll need to add a support chip, probably from FTDI, although there are a multitude of almost-FTDI clones available from the other parts of the Internet. These parts are slightly expensive, and they require some support circuitry. What you really need is a simple device that requires minimal external components, takes in serial from your microcontroller and spits out USB, and costs no more …read more
