Fermion: FTDI FT232RL Basic Breakout 3.3/5V

FT232RL USB-to-serial breakout supporting 3.3V and 5V operation. Features auto-reset via DTR pin, TX/RX LEDs, and microUSB input; compatible with Arduino serial bootloading.

GND / BLK1
Ground reference on the standard FTDI-style 6-pin header; DFRobot states the BLK orientation label corresponds to the ground wire colour on standard FTDI cables.
Type · groundVoltage · 0V
CTS2
Clear-to-send hardware flow-control signal on the standard FTDI cable-compatible 6-pin header described by DFRobot.
Type · signalVoltage · 3.3V or 5V TTL logic, selectable by jumper per DFRobot specification
VCC3
Selectable target/output supply pin on the FTDI breakout header.
Type · powerVoltage · 3.3V or 5V output, switchable via jumpers per DFRobot specification
TXO4
USB-to-TTL serial transmit output from the FT232RL breakout; DFRobot describes TX serial activity and FTDI cable-compatible pinout.
Type · signalVoltage · 3.3V or 5V TTL logic, selectable by jumper per DFRobot specification
RXI5
USB-to-TTL serial receive input to the FT232RL breakout; DFRobot describes RX serial activity and FTDI cable-compatible pinout.
Type · signalVoltage · 3.3V or 5V TTL logic, selectable by jumper per DFRobot specification
DTR / GRN6
DTR auto-reset signal exposed by the breakout; DFRobot states the GRN orientation label corresponds to the DTR wire colour on standard FTDI cables.
