TRU COMPONENTS 2315244 Micro USB 2.0 to UART-Converter Instruction Manual

TRU COMPONENTS 2315244 Micro USB 2.0 to UART-Converter

Intended use

This product enables USB connectivity in a device that has a UART interface (USB 1.1 or USB 2.0). The converter can convert TTL level (5V) and 3.3V level interfaces to USB. The converter board is soldered straight onto a circuit board or by means of a socket header, for example, or contact is made via socket headers (contact spacing 2.54 mm). This product complies with the legal national and European requirements. All names of compa-nies and products are the trademarks of the respective owners. All rights reserved.

Pin allocation

Pin number Name

• X1                                                                  TTL driver input (if not used, connect to GND!)
• X2                                                                  TXD 3.3Volt
• X3                                                                  RXD
• X4                                                                  TXD 5Volt TTL
• X5                                                                  GND
• X6                                                                  VBUS USB power output +5Volt/ 100mA

Software installation

First install the driver software

Only then should you connect the converter with the USB port. A Silicon Labs chip (CP 2102) is built into this board. The latest “USB to UART Bridge VCP / Virtual COM Port” drivers are available on the manufacturer’s home page: https://www.silabs.com.

3.3V and 5V level

3.3V level (TXD) is available at Pin X2. If you have a TTL level (5V) application, connect pin X2 to pin X1. You can then tap the TTL level at pin X4 (TXD_5V).

• If the TTL driver is not used, you should connect pin X1 to GND!
• The RXD pin X3 can only process signals between 3V and 5V. This is independent of the TXD driver wiring!
• When connecting a USB connection cable, make sure that the cable connections are established correctly. In case of voltage reversal, not only the converter is dest-royed but also the corresponding USB port. Loss of warranty/guarantee!

Disposal
