DSD TECH SH-U09C USB - TTLシリアルアダプター + FTDI FT232RLチップ Windows 10 8 7 Mac OS X対応

不具合無し

Help friends repair set-top boxes. There are many read-only software and binding ids, which can only be solved with this. The workmanship is very delicate, and the performance is stable, it is recommended to buy.

SONOFFのスマートスイッチ（EPS32）の書き換えのために購入。 書き込みエラーもなく必要な仕事をしてくれます。

ラズパイのベアメタル実験用にこちらの商品を購入し、ドライバを入れて人柱でどうなるか試しました。 M1Mac Studioのターミナルでは動作しませんでした（screenコマンド） 同機上にParallelsでWin11（Teraterm）とUbuntu（minicom）を導入、これも動作しませんでした。Win11ではデバイスマネージャーでドライバをそもそも認識しない状態。 Win10の別マシンではドライバ入れずにTeratermで一発動作。ラズパイはTX＞RXとRX＞TXとクロス接続です。念の為。

I can use it for Serial communication between many devices and also I can upload the firmware to Arduino devices with no built-in programmer. Amazing.

小さいし、出力変更できるし。ただ、供給電力は少ないので、調べてから買いましょう。

Switchの自動化をするために購入しました。 特に、面倒なソフトウェアのインストールなり、組み立てなりも必要なく、ストレスフリーに導入出来ました。

Nintendo Switchのとある作品でArduinoと併用して自動化をするために購入。 問題なく使う事が出来ました、配線等も解説サイトを見ながらやれば特に問題ないと思います。

A reliable, rock-solid USB to TTL Serial Adapter that gives you direct, low-level access to hardware. If you are into tinkering, flashing custom firmware, or recovering "bricked" electronics, this DSD TECH USB to TTL Serial Adapter is an absolute must-have for your workbench. I bought this for a specific weekend project: converting a locked-down $25 T-Mobile Cellspot (TM1900) into a fully unlocked ASUS RT-AC68U router. To perform that conversion, standard web-based firmware updates won't cut it. You need a direct, low-level hardware terminal connection to the router's processor—and this little adapter handled the job flawlessly. My Experience and Observations: • Genuine FTDI Chip Stability: The main reason I picked this specific adapter is the FTDI FT232RL chip. Cheaper serial adapters often use questionable clone chips that suffer from driver issues or erratic signal drops. This FTDI chip was recognized immediately by Windows without any driver headaches and provided a completely stable, rock-solid terminal connection throughout the entire process. • Essential for Low-Level Console Access: The adapter acted as the perfect physical bridge, converting my computer's USB signal down to the 3.3V TTL signal expected by the router's internal PCB headers. It allowed me to bypass the ISP's bootloader locks, interact directly with the CFE (Common Firmware Environment), dump my original MAC address backups, and clear the NVRAM manually. • The Ultimate "Debricking" Lifeline: When you're modifying bootloaders or flashing non-standard firmware, there is always a risk of a bad flash leaving you with a dead device. Having this serial connection hooked up to read real-time boot logs is the only way to diagnose boot failures and manually re-flash corrupted partitions. • Helpful Status LEDs & Voltage Switch: The onboard LEDs for TX, RX, and Power are incredibly helpful for verifying that data is actually moving back and forth when debugging. Plus, the jumper switch makes it very easy to toggle between 3.3V and 5V logic depending on what board you are working on. Final Thoughts: This $10–$15 adapter allowed me to transform a cheap $25 ISP unit into a high-performance, fully featured ASUS router that would have otherwise cost over $100. If you need a reliable serial interface for debricking routers, flashing microcontrollers, or hardware debugging, this DSD TECH unit is worth every penny. Highly recommended!

Adattatore uart perfetto e funzionale . Sono riuscito ad interfacciarmi coi un vecchio modem/router linksys bloccato e piallarlo a dovere prima di ricaricare firmware mod.

Good Solution for Serial port converter, used to reset the Electronic devices. Thank you.

Honestly I havent used for some reason not related with product.

usb to rs232 works well easy to get up and running . no software (drivers) required for windows or linux
