Review: Had to comment on Packaging - First, what serial device comes with printed color instructions on how to use a terminal? I got this to add the the big collection of serial converters one needs to talk to all sorts of IC modules. Hint: there are 6 different serial chips/converters out there, and you need most of them. If you find a device to connect and you just have to give up because no baud rare works? Nah, switch to a different converter and there like a 90% chance it will just work. But the packaging with this one was very impressive, so much so I had to get online and write a comment on it. If you're wondering, here are the other converters I've had to switch between over the years (and a can bus one). Not because they are bad, it's just it's a hit or miss. Also, don't believe those "throw away all ur converters" all-in-ones, they are just one of the chips i link to below (and a lot cheaper): https://amzn.to/45JWosC, https://amzn.to/45N6nNO, https://amzn.to/3VUVvtQ, https://amzn.to/4cifhVP Lastly, if I had any negative, it would be that more converters need GPIO pins to flip bits and power cycle things. My crowd supply version works very well for that. ## Features - DSD TECH: DSD TECH focuses on the development of serial devices such as TTL/RS232.We have served more than 100,000 customers in total. - Silicon Labs CP2102N:CP2102N is an upgraded version of CP2102 chip, the maximum transmission speed can reach 3Mbps, which is equivalent to FT232RL. - 1.2M/4 Feet:The length of this USB to TTL serial cable is 1.2M/4 Feet.

These always work, have never broken, and the labels on the connectors are great so you don't have to remember what color is what signal. A couple more dollars than some other options, but definitely worth it. ## Frequently Bought Together - DSD TECH SH-U09BL USB to TTL Serial Cable with CP2102N Chip 1.2M/4FT - ELEGOO 120pcs Multicolored Dupont Wire 40pin Male to Female, 40pin Male to Male, 40pin Female to Female Breadboard Jumper Ribbon Cables Kit Compatible with Arduino Projects - DSD TECH SH-U09G USB to TTL Serial Cable Built-in FTDI FT232RL IC 1.8M/5.9FT --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.de/products/237111253-dsd-tech-sh-u09bl-usb-to-ttl-serial-cable-cp2102n](https://www.desertcart.de/products/237111253-dsd-tech-sh-u09bl-usb-to-ttl-serial-cable-cp2102n) --- *Product available on Desertcart Germany* *Store origin: DE* *Last updated: 2026-04-22*
