As much as we love our FT231XS USB-Serial adapter, we feel that the cost of the FT231XS chip is a bit on the high side. When we found the super cost effective CH340G chip made by Chinese company WCH, we thought that this could a very good alternative to the FTDI based chips. There are many cheaper version available in the market but we want to make one that we would love to use in our everyday work from uploading sketches to debugging serial devices! If you are dealing with 3.3 V and 5 V serial devices, these are very handy and cheap. But, if you need to interface with lower voltage like 2.85 V, we recommend using our FT231XS version instead.
- Supports 3.3 V & 5 V Operation
- Convenient slide switch to select voltage level of operation
- Up to 100 mA of 3.3 V provided by on-board LDO available for use
- Compatible with Arduino Boards (for example: Arduino Pro/Pro Mini)
- Compatible with NXP ARM LPC Series (combination of DTR & RTS pin to push the LPC chip into bootloader mode using Flash Magic)
- 500 mA fuse for USB port over current protection
- Solder jumper at the back to select the available supply voltage on the 6-pin receptacle header
- USB micro connector with 4 through hole pegs for reliability
- 2 LED for TX (red) & RX (green) indication
- All pins are broken out to 2 rows of standard 0.1″ spacing header
- Drivers available for Windows, Mac (requires some workaround for OS-X Yosemite and El Capitan), and Linux
