## Customer Reviews

### ⭐⭐⭐⭐⭐ Works great to program a GOTEK with FlashFloppy!
*by U***R on April 20, 2019*

It's true, this really has a genuine FTDI FT232RL IC. Why is this important? First, aside from "FTDI-gate" the reputation of FTDI being more reliable than Prolific chips I've experienced firsthand. And second, no driver surprises with fake FTDI or having quality control issues with bad ICs.I bought this to program FlashFloppy firmware onto a GOTEK floppy emulator. So glad I purchased DSD TECH brand because compared to the ones selling for half the cost elsewhere you get so much more. For instance you get a quality case, a mini USB cable, and some DuPont cable. Plus help is there if you need it. Which reminds me, if you also need the 128*32 OLEDs, DSD TECH sells them too! [Beats waiting a month to get them from you know where.]

### ⭐⭐⭐⭐⭐ Works well, sturdy design
*by M***. on February 22, 2020*

After seeing a lot of bad reviews for programmers which don't use the real FTDI chip, I decided to pay an extra $3-5 to get this one based on the other reviews. There's a reason this board gets such good reviews. The plastic case makes it easy to hold without worrying about damaging the board, and the instructions are very straightforward. Set the jumper to the correct voltage for txd/rxd for your board, attach the wires, and plug it in. I did not measure the current supply, but one board I was using it with kept complaining about "brown out condition detected". It could be my laptop's USB port though. Just keep in mind that you might have to power the board you are programming from a separate source.

### ⭐⭐⭐⭐⭐ Excellent USART for microcontrollers
*by J***N on March 8, 2021*

this is a great serial controller. It can be configured between 3.3v and 5v. I am using this as a debugger for my microcontroller ( STM32 and ESP32 ) projects. I built a custom harness with the jumper integrated so I don’t worry about overloading my chips. I love that It has leds for transmitting and receiving. I am using this primarily as a debugger which I use SERIAL ( Mac app ) and it simply works ( no driver installs, just plug and play ). just remember that the TX on your board will connect to the RX on the receiver.
