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
UART I/F Supports 7 / 8 Bit Data, 1 / 2 Stop Bits and Odd/Even/Mark/Space/No Parity
Data rate 300 => 3M Baud (TTL)
Data rate 300 => 1M Baud (RS232)
Data rate 300 => 3M Baud (RS422/RS485)
384 Byte Receive Buffer / 128 Byte Transmit Buffer for high data throughput
Adjustable RX buffer timeout
Fully Assisted Hardware or X-On / X-Off Handshaking In-built support for event characters and line break condition

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
