Description
ConverterµUSB-PA5-IIprovidesa connectionbetween two popularserial interfaces USB and UART. The module is based on aCP2104. It has a compact size and has additional outputs on the sides of the board. PinsRX and TXcan work both on3.3 V and 5 V. It has aminiUSB connector and an LED indicating the state of power supply, sending and receiving data.
The module can be used to exchange data between the computer and the system or microcontroller or for programming boards with remote serial interface, e.g.ArduinoorSTM32Discovery. The operating system is visible as a virtual COM port.
