User manual

The FT232R UART/USB breakout
Used to communicate UART data (8-bit) over
USB.
Powered by the USB connector’s 5 Volts.
Regulates this down to 3.3 Volts.
Supports RTS/CTS handshake.
Max baud clock is counted down from 3 Mbs.
Integer divide factor.
I’ve successfully used these at 1.5 Mbs and 3.0
Mbs.
I’m using FTDI’s D2XX direct drivers on the
RPi (the USB end). I located a special build for
RPi’s hard float. FTDI’s V1.1.12 only supports
soft float. The HF and SF calling sequences are
not compatible.
