Micro USB to Serial Adapter is a usefull tool that allows to connect Personal Computers with any microcontroller system via the USB port. This tiny and lightweight board is only 19x13 mm, including the mini-B connector, and its weight is only 1,4 gr (0,05 oz). Interfacing is realized by two 0,100” strip connectors that are distant 0,600” (15,24mm); this allows a stable and easy mounting on solderless breadboard and sockets.
When you plug the board into the USB port, the PC system will recognize it as a serial VirtualCOM Port (VCP) which will realize the communication with the microcontroller system connected to the Micro USB to Serial Adapter; this allows to use systems designed to work with the RS232 serial port without modifying them.
This device operates at data signaling rates up to 921,6kbit/s. Besides TX and RX signals, CTS and RTS are also available for handshaking procedures (see table 2). The USB Suspend and Resume signals are supported for power managment. The device will enter the Suspend mode when suspend signaling is detected on the bus.
The board is provided with two 0,100” strip connectors.
