USB-UART FTDI232RL

The FTDI232RL USB-UART module is a device for communication between USB and UART interfaces. The converter can be used as a programmer for Arduino MINI, Arduino Nano or other microcontroller based devices.

The converter board is designed based on the FTDI232RL chip. The FTDI232RL chip has 28 pins and is made in the SSOP-28 package, which creates a virtual COM port when the converter is connected to a PC (personal computer). The chip also supports 7 and 8 bit data transfer modes and has a built-in EEPROM memory with a capacity of 1024 bytes.

The FTDI232RL converter is connected to the USB port of the PC using a USB type A - mini-USB type B cable (not included), and to the microcontroller device using the UART interface. Interface pin assignment:

VCC: output power
GND: ground
DTR: external device ready signal
RxD: signal receiving line
TxD: signal transmission line
CTS: Transmission Stop Signal

There are also 3 LEDs on the USB-UART converter board:

PWR: signals power supply
TX: Lights up when transmitting data
RX: Lights up when receiving data

When connecting the converter to the Arduino platform or other microcontroller devices, remember that RxD is connected to the TX controller pin, and the TxD pin of the converter to the RX microcontroller.

To work with this converter, you need to download and install drivers. If, when connecting the device to the PC, the drivers were not installed automatically, then you need to download them fromlinkand install manually. It is not recommended to install a converter driver higher than version 2.10, as this may cause the device to malfunction.

Voltage is supplied from an external power source, Arduino platform or any other microcontroller device. The output voltage of the module signals is 3.3 or 5 V. There is a jumper on the module board to adjust the voltage. It is also possible to supply power from a personal computer using a USB connector (5 V).
