This is the newest revision of our. We now use a SMD 6-pin header on the bottom, which makes it smaller and more compact. Functionality has remained the same. This is a basic breakout board for the FTDI FT232RL 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. The major difference with this board is that it brings out the DTR pin as opposed to the RTS pin of the FTDI cable.

Official Atmel AVR development tools and evaluation kits contain a number of starter kits and debugging tools with support for most AVR devices.

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, but this board requires a Mini-B 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. Note: We know a lot of you prefer microUSB over miniUSB. Never fear, we’ve got you covered! Check out our for your micro FTDI needs! Not sure why there are two separate versions of these FTDIs.

As has been previously pointed out, there is a 3.3V pad and a 5V pad, with the output in the center. The only difference between the FTDIs seem to be where the trace is coming from. I had bought a 3.3V FTDI and I need it to supply power to a 5V Arduino Pro Mini. Per bboyho’s post, I cut the 3.3V trace and created a solder bridge between the 5V and center pads. It worked fine, but I still needed 3.3V.

So, I mounted a small switch to the FTDI and did some really fine soldering to the pads. It’s not pretty but it works like a charm. I would like to introduce you to the scm which is an alternative library to rxtx/javaxcomm for serial port communication.

I have tested both CP2101 and FT232R from spark fun successfully. Wiki: Repository: Video: It supports RS-232 control signals handshaking, monitoring and has been ported to Linux, MAC, Solaris and Windows operating system. It is consistent, portable, efficient, reliable, testable, extensible, modifiable, scalable library. •. I use this to send sketches to a prototype that uses a “bare” ATmega328 chip (on a breadboard. Steam Client With Full Steam Cache. To program the chip I hooked up the FTDI DTR pin to the RST pin via a.iuF capacitor, the FTDI RX pin to the TX pin and the FTDI TX pin to the RX pin on the ATmega328 chip. I didn’t use the 3.3v pin. I used as the starting reference because I couldn’t find clear instructions on SparkFun.

I use the Arduino IDE to load the sketch and can monitor serial traffic just as if I were hooked up to an Arduino. There really should be an option of connecting 5V ( unregulated 500mA USB ) to the FTDI header and keeping the VCCIO at 3. Free Download Film The Raid 2 Berandal Bluray on this page. 3V.

This would make the circuit identical to the FTDI 3V cable. I don’t understand the point of providing the current limited 3V ( that is only intended on driving VCCIO ) to the header. One great feature of the FTDI pinout is providing the 500mA at 5V USB raw for powering a projects local LDOs to 3.3V on down. This board only supports that if using 5V IO.

According to the FTDI232R spec, the 3V3OUT can only provide 50mA. Plugging this 3V board into an FTDI compatible circuit requiring up to 500mA will certainly cause problems for the FTDI232R. I bought one of these and now realize I must hack it up to use it without damaging it. There is something I miss. You say: “The major difference with this board is that it 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.'

But really this pcb behaves reverse and I MUST PUSH reset button in order to download a new Sketch. I’ve tested this with several Arduino boards with the same result. Can you have a look at this????
