SparkFun will be closed Friday 7/3/2020 for the 4th of July holiday. All orders placed after 2 pm MT on Thursday 7/2/2020 will be shipped out on Monday 7/6/2020. SparkFun Support will also resume on Monday 7/6/2020. Have a safe holiday!
This is SparkFun Beefy 3 FTDI Basic Breakout for the FTDI FT231X USB to serial IC. The pinout of this board matches the FTDI cable to work with official Arduino and cloned 3.3V Arduino boards. It can also be used for general serial applications. Built upon the same foundation as our 3.3V SparkFun FTDI Basic Breakout, the Beefy 3 is equipped with an AP2112K voltage regulator making this FTDI basic breakout board capable of handling a current load of up to 600 mA! With the addition of a more "Beefy" voltage regulator your will now be able to power a 3.3V project directly from the FTDI. The pinout of this board matches the FTDI cable to work with official Arduino and cloned 3.3V Arduino boards.
This board brings out the DTR pin as opposed to the RTS pin of the FTDI cable. The DTR pin allows an Arduino target to auto-reset when a new Sketch is downloaded. This is a really nice feature to have and allows a sketch to be downloaded without having to hit the reset button. This board will auto reset any Arduino board that has the reset pin brought out to a 6-pin connector. The pins labeled BLK and GRN correspond to the colored wires on the FTDI cable. The black wire on the FTDI cable is GND, green is DTR. Use these BLK and GRN pins to align the FTDI basic board with your Arduino target.
There are pros and cons to the FTDI Cable vs the FTDI Basic. This board has TX and RX LEDs that allow you to actually see serial traffic on the LEDs to verify if the board is working, however this board now requires a Micro-B USB cable. The FTDI Cable is well protected against the elements, but is large and cannot be embedded into a project as easily. The FTDI Basic uses DTR to cause a hardware reset where the FTDI cable uses the RTS signal.
This board was designed to decrease the cost of Arduino development and increase ease of use (the auto-reset feature rocks!). Our Arduino Pro and LilyPad boards use this type of connector.
If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.
Skill Level: Rookie - You may be required to know a bit more about the component, such as orientation, or how to hook it up, in addition to power requirements. You will need to understand polarized components.

Able to connect to Wi-Fi modules without power loss. Great product.
I used the beefy for the NRF52832 board. Works with no problem.
FTDI boards with external 3.3V power supplies are rare these days, this board does the job and operate our testing setup perfectly, very happy with the results so far!
I really didn't want to worry about current draw in the 3V project I was working on. And the auto-reset on upload is totally handy. I still use the cable on my 5V projects, but it's less handy to have to remember to hold down the reset button every time you upload. I don't know how many 3V projects I'll work on, but I'm confident this little board will handle them with no problems.
This worked great right out of the box with Arduino. No driver download was needed, Windows 10 handled it automatically.
I tried knockoff FTDI boards because I was in a pinch and borrowed an FTDI cable from a friend and had no luck programming a SparkX board. The beefy is compact and works flawlessly everytime.
easy to use, good form factor, excellent support.
