Works great as an ATmega328 programmer. Works from the Arduino IDE. I had to install the driver, was easy to do. If you are new to the Arduino prototyping platform make sure you connect a 16MHz crystal, 22pf load capacitors and a resistor to the chip if you are using a breadboard project. There are diagrams online. With the connections some schematics refer to DTR, this is the same ad RTS with this module. Review: Works out of the box no issues - Worked perfectly straight out of the box - bought other cheap ones on desertcart but had to return due to failing to work. Was successfully able to connect to a device via UART. No drivers required to be downloaded for either Windows 11 or Raspbian. ## Features - DSD TECH: DSD TECH focuses on the development of communication connection devices such as USB/Serial/Wireless.

It only converts from RS232 to TTL logic levels (and back again). There are some handy LEDs that flash when data is being transferred. **Q: Sorry for stupid question( I am a begginer) can it work as updi programmer also?** A: It's a RS232 serial port **Q: Does this device support Xon/Xoff on board, or can any buffering be removed to ensure xon/xoff works correctly ?** A: It is a "dumb" level shifter with a small buffer on the comms chip and will implement whatever parameters you set up for your comms. Xon/Xoff is implemented in the software flow of the comms software you use (decimal values of 17 and 19) and these characters and are treated in the same way as other data. It is the comms software that has to deal with Xon/Xoff not the DSD adaptor. **Q: Does this work with Mac catalina?** A: macOS Catalina (version 10.15) is the sixteenth and, as of May 2020, current major release of macOS. In the description for DSD TECH USB to TTL Serial adapter is says it supports mac, so yes. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great USB to TTL converter *by C***S on 6 November 2019* I really like this USB to TTL serial converter, well designed.

Was successfully able to connect to a device via UART. No drivers required to be downloaded for either Windows 11 or Raspbian. ### ⭐⭐⭐⭐⭐ Surprised to find a great product! *by C***H on 10 August 2023* I recently purchased the DSD TECH USB to TTL Serial adapter with FTDI FT232RL Chip from Amazon, and I must say that I am highly impressed with the quality of this product. This adapter is far superior to similar products due to its transparent case, which not only looks great but also protects the adapter from wear and tear over time. What sets this adapter apart from competitors is its unique casing – most other adapters do not come with a case, leaving them vulnerable to damage from everyday use. This is especially true if you use the adapter regularly, as exposure to the elements can cause damage to the internal components of the adapter. The DSD TECH USB to TTL Serial adapter's casing provides excellent protection against this, ensuring that your adapter will last for a long time. Another great feature of this adapter is that it comes with connection cables and a voltage changer. The voltage changer enables you to switch between 3.3v and 5v, which is highly useful if you are working with different types of devices or electronics. Additionally, the included cables make it easy to connect to any USB-enabled device. Overall, I would highly recommend the DSD TECH USB to TTL Serial adapter with FTDI FT232RL Chip to anyone who works with electronics on a regular basis. The quality of the product is exceptional, and the included features make this adapter stand out from the rest. Whether you are a professional or a hobbyist, this adapter will meet all of your needs and expectations. ## Frequently Bought Together - DSD TECH SH-U09C USB to TTL Serial Adapter with FTDI FT232RL Chip Compatible with Windows 11, 10, 7 and Mac OS - 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 - Goupchn Test Hooks to Breadboard Female Jumper Wires Soft Flexible Silicone Test Leads for Electrical Testing --- ## 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.pl/products/716223681-dsd-tech-sh-u09c-usb-to-ttl-serial-adapter-ftdi](https://www.desertcart.pl/products/716223681-dsd-tech-sh-u09c-usb-to-ttl-serial-adapter-ftdi) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-05-08*
