Cheap USB to UART Converter using Microchip MCP2200

Post by sam.mo » Sat Feb 27, 2021 6:13 pm

Nowadays USB port is used widely for data transactions between electronic devices and computers. In many scenarios, there is no need to communicate with the USB port directly, therefore electronic designers use USB to UART (RS232-Serial) converter chips, so the USB port is converted to a virtual COM port on the computer. The initial thought of many designers is to use FTDI chips to do the USB to UART conversion. There is nothing wrong with FTDI chips, however, they are expensive. In this article/video, I introduced a cheap USB to UART converter module that uses the MCP2200 chip from Microchip. The converter supports both 3.3V and 5V serial logic levels and uses three LED indicators for power connection, data transmission, and data reception.

The module supports the serial CTS and RTS pins, also six GPIOs that can be used for direct controlling of connected devices. The serial data of the module has been examined and decoded using the UART decoding feature of the Siglent SDS2102X Plus oscilloscope. So let’s get started!

Thank you for sharing.
What examples of typical use case do you see for this in conjunction with a Red Pitaya unit that already has UART capability?

They can use the oscilloscope function to examine the USB/UART signals
