FTDI Basic Breakout USB to TTL Upload Tool for MWC for Arduino (Works with Official Arduino Boards)

Pros: Plug and play. Comes with it's own mini USB cable. Easily recognized by the OS, uses the same FTDI drivers that come with Arduino. Clear markings on the pins. Has TX and RX LEDs to see what's going on. Half the price of other "brand" products, while offering the same functionality (or at least what interests me). Comes very well packaged, the board is bubble wrapped and then packaged with the cable in a cardboard box.

Cons: None.

Other: Works great for programming ATMEGA-328 chips directly on the breadboard. Very easy to use.

Pros: This is a USB-to-serial adapter based on a real (as in "not fake") FTDI chip. It is used to program most atmel AVRs that can be programmed through the serial pins, like the arduinos. Its greatest advantage is that it features a DTR pin, so there is no need to hold RESET LOW while programming, since this board will do it for you (provided you plug it correctly - a 100nF capacitor is required between DTR and RESET). It works flawlessly with Win7 x64, and the drivers can be downloaded from http://www.ftdichip.com/Drivers/VCP.htm I have been using this with breadboard arduinos (like on the pics I have uploaded to DX) and it all works great. The 5V output in the board (taken from the USB) can be used to power the breadboard, so there is no need to use an extra power source when working with this. The output current must be limited to 500mA.

Cons: None, absolutely none! You get more than you paid for!

Other: For arduino enthsiasts, this is the best USB-2-Serial adapter out there.

Pros: Very good prodouct with a very good shipment. Works good in Win7 64bits with auto instal. No more drivers are needed. It has two leds indicating when is sending or transmitting data.

Cons: The usb cable is too short, more or less 10cm. No more cons about this prodouct.

Other: A good prodouct with a good price, is a confortable thing.

Pros: It has all signals needed for your arduino to upload your sketches or use as a serial adapter for router unbricking.

Cons: The included cable is short, but built like a tank and is pulling it all around.

Other: must-have for anyone, who is tossing botloaded atmegas everywhere and needs to upload and update them without an arduino board.

Pros: Works as desired. Plugged into usb port, enemerates as a usb-serial adapter, works without incident. Has a green led for RX and a red LED for TX. Baudrates configure just fine.

Cons: I would been nice to have the RTS pin broken out for a project I'm working on; though it is pretty rarely needed.

Other: It's much more convenient that adding MAX232 chips and power connected to microcontroller projects. I plan on getting a couple more.

Pros: 1. The cheapest FTDI adapter on DX so far 2. Worked as expected with Arduino Pro Mini 3. Comes with USB cable 4. Does not require any special drivers - my Windows 7 machine found the drivers on windows update 5. Build quality is very good 6. Tx and Rx LEDs indicate when the communication takes place

Cons: 1. The USB cable could have been longer. No other problems found

Other: Highly recommended for serial communication between a computer and embedded systems requiring TTL levels.
