You can check more details from our website for more details. I am writing to you just advise that we Micro controller buy FTDI USB to TTL 3.3V & 5V from our company, the price is $7.8 for 3.3v, and $7.9 for 5v. We are a profesional manufacturer of HDMI cable, USB cable, etc. If you like hacking like I do and may brick your router a few times while playing with it get the right cable and make it easy to debrick as shown here for the WGR614L and here for the WNR3500L.
They also make other boards or you can just buy the chip by itself at the end of the day, I just don't think it is worth the effort compared to buying the cable itself. You could buy a Mini-USB to Serial UART (TTL) Breakout Board, 3.3V and plug a standard USB cable into it and then solder wires from there but for a $5.00 savings it's probably not worth it. This allows you to communicate with the USB interface via a standard PC serial emulation port (for example TTY or PUTTY). These cables require USB drivers to make them work, but they are available free from, which is then used to make the FT232R chip in the cable appear as a virtual COM port (VCP) on your computer. They use FTDIÂ’s FT232RQ USB to Serial UART interface IC device which handles all the USB signalling and protocols. The key to these cables are that each one contains a small internal electronic circuit board, utilizing the FT232R chip, which is encapsulated into the USB connector end of the cable. They come with different types of connectors Bare Wire, 6 Pin SIP and Audio Plug Connector.īut the business end, the USB side is very different than a standard USB cable. The answer is basically no - allow me to explain.įirst of all I recommend the USB-to-Serial Cable: 3.3V TTL cables that are available here. I will be happy to modify or delete this question.I have been asked a few times if there is a way to convert a basic USB cable to allow it to connect to your WGR614L/WNR3500L. If there is or are any problems with my question, please let me know. Question 2. If I connect the RX(GPIO 15) and TX(GPIO 14) from my Raspberry Pi to this router RX_0 and TX_0 only(yes with RX_1 and TX_0 both unconnected), would it work? (I assume not) or do I have to pair all two TXs and RXs between Raspberry Pi and router? Question 1. What is the name of that 10 Pin layout from my router? Does this have any name? or is it just a ‘Serial’ layout? This is the point that I get some confusion and decided that I should ask you about this question. However, Raspberry Pi has only one pair of RX(GPIO 15) and TX(GPIO 14). I have found out that Raspberry Pi supports UART connection by default. I am planning to connect those pins with my Raspberry Pi 4 with GPIO pins. This is the pinouts for the router that I would like to debrick. Since this is my first time with Serial communication on any device, I have some questions to ask. I was working on a project that ‘debricks’ my bricked router(WRT54GL).
