Access a computer’s USB connection as a UART with this FT231X breakout. The board exposes the chip’s pins beyond the usual programming header, including hardware-handshaking signals. A Micro-B connector handles USB, providing an adapter option for serial development tasks that need additional modem-control or flow-control connections alongside transmit and receive.
Before you buy
