Description: The CY7C65213 USB to UART serial breakout is designed to provide users with a means to access all available I/O pins on the IC, and to provide a 6-pin UART header that is compatible with other SparkFun breakout boards. This breakout has a microUSB connector and other support circuitry to get the IC quickly up and running.

The CY7C65213 breakout is equipped with a micro-B USB port, USB signal lines, a VIO selection jumper, a low-voltage selection jumper, and a multitude of pins that allow you to utilize the board to its fullest potential. The CY7C65213 breakout is capable of operating at both 3V and 5V based on what the VIO selection jumper is set to. Additionally this breakout can operate at 2V and below.

  • It seems rather obvious to me anyway that the solder jumper would be much more useful as a 3 position switch. Why risk lifting the pads or damaging the board with a soldering iron when you could have used a convenient switch in its place.

    • Unfortunately there is just not enough room on this board to put a switch on the PCB. You can however clear the jumper, and wire your own switch to the 5V, 3.3V and VIO pads beside it. That would allow you to easily change voltage from 5 volt to 3.3 volt with just the flick of a switch.

  • What are the benefits of this over the ftdi board - other than it not being from ftdi?

    • I notice the datasheet says the default baud rate is 115200. I think the FTDI stuff from sparkfun at least (e.g. DEV-09716) is stuck at 57600 (at least that’s the rate the works for me with avrdude).

      So hopefully you could get twice the upload speed when using non-rev3 Arduinos (e.g. sparkfun Arduino pro, pro mini, etc.). Sparkfun can you confirm this?

      Together with the avrdude -V option to disable verification edit/compile/debug of large sketches becomes much less painful.

      • The data rate of uploading is actually set by the bootloader programmed into the chip, so the Pro/Pro Mini will always be limited to 57600, regardless of the serial bridge you use.

        Sadly, it’s unlikely that we’ll change the Pro/Pro Mini bootloader anytime soon, as that would render the IDE incorrect and unable to upload.

    • Not being from FTDI is a sufficient selling point in some situations. The FTDI chips are popular for non-serial-port applications, some of which require (under Linux, anyway) unloading the ftdi_sio driver and thus rendering regular serial dongles inoperative for the duration. In such a case, having a couple of Brand-X serial dongles around, using a different driver, is very helpful.

      • Agreed, FTDI has a pretty bad name in the tech community these days. I recently was looking on Sparkfun for a non-FTDI option to evaluate for a project, but there wasn’t anything, so this is good to see. I ended up using this: http://prolificusa.com/portfolio/pl2303sa-usb-serial-bridge-controller/ as an awesome little 8-pin chip just for RX/TX. @Sparkfun: the PL2303SA with a tiny breakout could be a nice minimal non-FTDI option, too, and it can also go all the way down to 1.8V.

        • To be specific about why they have a bad name, FTDI released windows drivers that deliberately bricked FTDI clones. In other words they deliberately destroyed the hardware of users that likely had no idea they were even using a clone. I’ve been eager to ditch them for good ever since I learned this.

    • The ability to operate all the way down to 1.8V? That’s the most significant difference.

  • Hi gang, I’ve put together a fork of python-ucdev which will let you access the CY7C65213 GPIO pins from python with simultaneous pyserial communication. There’s also a guide showing how to get it up and running on Linux (Raspberry Pi). https://github.com/PaulZC/python-ucdev Enjoy, Paul
