Short TX, RX means you will receive any data you send. When you program or debug, you can quickly confirm if the TTL adapter is damaged. It saves you time and quickly locates faults. **Q: What is the maximum baud rate of this device?** A: Build-in FTDI FT232RL Chip, max speed is to 3Mb/s . After testing, we found that data can be transmitted stably below 115200 baud rate. **Q: Does this work with the arduino ide to upload sketches to the arduino pro mini?** A: yes ,it work with arduino ide to upload sketches to pro mini. **Q: I want to confirm, 5v from the usb side is output to vcc as 5v or converted to 3.3v /1.8v by jumper and sets ttl interface level correct?** A: Hi, I just checked this on mine with a DMM to verify. Your assumption is correct: the jumper will alter the VCC to 5/3.3/1.8V. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by K***I on January 21, 2025* 安価だったので、単独目的でしたが購入してみました。 Jetson上で動作させるソフト開発でしたが、40pinDIO部の動作確認用に使いました。 動き始めてしまえば不要となりましたが、オシロやロジアナ出してこなくて済んだのでコスパ良かったです。 ### ⭐⭐⭐⭐⭐ Review *by A***ー on March 4, 2021* 問題なくつかえました。秋月のESP-WROOM-02 DIP化キットに書き込みたくて購入しましたが、問題なく書き込めました。素人過ぎて、はじめは電圧の切り替えの仕方がわかりませんでしたが、ジャンパーピンを使いたい電圧に差し替えるだけなんですね、、、よく見りゃ画像でも説明があった、、、とにかくよい製品です！ ### ⭐⭐⭐⭐ Review *by わ***い on December 4, 2021* チップ単品では、I/O電圧(5V/3.3V)が1.8Vにも対応。FTDI製のツールも使え動作に問題はないようです。 (某社の偽物FT232RLは、ツール上チップを認識せず) ただ、形状がやや大きいためパソンコンでUSBポートが隣接している場合、ポートにさせない可能性あり。 自分のパソコンでは、させなかった。 ## Frequently Bought Together - DSD TECH SH-U09C2 USB to TTL Adapter Built-in FTDI FT232RL IC for Debugging and Programming - 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.id/products/731464129-dsd-tech-sh-u09c2-usb-ttl-converter-adapter-with-ftdi](https://www.desertcart.id/products/731464129-dsd-tech-sh-u09c2-usb-ttl-converter-adapter-with-ftdi) --- *Product available on Desertcart Indonesia* *Store origin: ID* *Last updated: 2026-05-15*
