It’s a blast-from-the-past with these FT232BL chips that we found while cleaning out a shelf at Adafruit. We haven’t used these for years, having moved to the FT232R and CP210x. Stiiiiiiiiiilllll……..with the silicon shortage, some folks may be building very old designs and need some of these ancient chips. No problem! We give you 10 pieces off of the reel, so you get one or two cut tape strips. They’re a little long-in-the-tooth, and we don’t recommend them for new designs, but they’ll work just as you expect.
The FT232B is a USB to serial UART interface with the following advanced features:
Single-Chip USB to Asynchronous Serial Data Transfer
Full Handshaking & Modem Interface Signals
