Worth the price of admission. ### ⭐⭐⭐⭐⭐ Worked Well *by E***S on January 25, 2021* I used this to update the firmware on a DSO138 oscilloscope using the ST Flash Loader Demonstrator software. Remember to print out the graphic for the switch positions as a switch instructions sheet is not included. Windows recognized the device without problems setting up a new Com port. Remember to connect TX-RX and RX-TX between the devices. ### ⭐ Lots of wasted time. *by C***. on October 5, 2022* So using the first configuration line to connect USB to TTY serial, only the USB led lit. the kernel module showed loaded. but still no TX /RX. Returned for a replacement, same thing. I liked the design, if it worked. ## Frequently Bought Together - NEXTION CP2102 6 in 1 USB to TTL Serial Adapter Module USB to TTL 485 232, TTL to 232 485, RS232 to 485 + 4P Dupont Cable Jumper Wire Female for N e x t i o n Display - NEXTION Enhanced IO Adapter GPIO Expansion Board Enhanced 2.4" 2.8" 3.2" 3.5" 4.3" 5" 7 Intelligent Display 7 10.1 inch - Nextion 3.5″ Enhanced HMI Display Module NX4832K035 Resistive LCD-TFT Touch Screen 480 * 320, Nextion Display with RTC Function and 8 Digital GPIOs, Suitable for 3D Printers, Vehicle HMI, etc. --- ## 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.tn/products/126091284-nextion-cp2102-6-in-1-usb-to-ttl-serial-adapter](https://www.desertcart.tn/products/126091284-nextion-cp2102-6-in-1-usb-to-ttl-serial-adapter) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-06-11*
