The module is universal converter from USB to RS232 with TTL/CMOS signal levels (both 3.3V and 5V). The converter uses FT232R chip from FTDI and is supported in all main operating systems.
The module uses well known MAX232 chip and is intended as a level converter. It uses RX/TX signals and a pair of flow control signals (selectable by jumpers). Original RS232 signals are available on header pins.
The module allows the generation of PWM signal, which can be adjusted using the I2C interface. The module has eight outputs that can run simultaneously on two frequencies in the range of 0.59 Hz - 152 Hz (with 1.69 - 6.58 ms).
