Featuring a genuine FT232RL chipset alternative, it supports 3.3V and 5.5V operation, includes a 500mA self-resetting fuse for protection, and offers broad compatibility with Windows OS versions up to Windows 7. Its mini USB connector and lightweight design make it an essential tool for makers, developers, and automotive tuners seeking efficient, solder-free connectivity. ## Description The best way to program the Arduino Pro Mini is with the FT232RL TTL converter. Just install the FTDI drivers and you're all ready to program. I don't even solder on pins. Just slide the Arduino over the pins of the ft232rl and hold it while you upload. ## Features - Chipset: FT232RL not genuine FTDI chip Working Voltage: 33V/55V - RXD/TXD transceiver communication indicator with 500MA self-restore Fuse - Pin Definition: DTRRXDTXVCCCTSGND - Support Win95/98/98se/ME/2000/XP/win7 32bit 64bit /Vsita/ do not Support Win8 - Chipset: FT232RL, not genuine FTDI chip, Working Voltage: 3.3V/5.5V - RXD/TXD transceiver communication indicator, with 500MA self-restore Fuse - Pin Definition: DTR,RXD,TX,VCC,CTS,GND - Support Win95/98/98se/ME/2000/XP/win7 32bit 64bit /Vsita/, do not Support Win8 - Brand: HiLetgo - Connector type: Mini USB ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00IJXZQ7C | | Best Sellers Rank | #5,408 in Computers ( See Top 100 in Computers ) #7 in Serial Adapters | | Brand | HiLetgo | | Color | Red | | Compatible Devices | Personal computer, laptop, desktop | | Connector Type | Mini USB | | Current Rating | 0.5 Amps | | Customer Reviews | 4.4 4.4 out of 5 stars (1,160) | | Finish | Matte | | Input Voltage | 5.5 Volts | | Item Dimensions | 15.2 x 1.3 x 10.2 centimeters | | Item Weight | 0.01 Kilograms | | Manufacturer | HiLetgo | | Mfr Part Number | 3-01-0661-1 | | Model Number | 3-01-0661-1 | | Number of Items | 1 | | Number of Ports | 1 | | Package Quantity | 1 | | Power Plug Type | No Plug | | Specific Uses For Product | personal | | UPC | 509049833148 | | Unit Count | 1.0 Count | ## Product Details - **Colour:** Red - **Compatible devices:** Personal computer, laptop, desktop - **Connector type:** Mini USB - **Item dimensions L x W x H:** 15.2 x 1.3 x 10.2 centimeters - **Specific uses for product:** personal ## Images ![HiLetgo FT232RL FTDI Mini USB to TTL Serial Converter Adapter Module 3.3V 5.5V FT232R Breakout FT232RL USB to Serial Mini USB to TTL Adapter Board for Arduino - Image 1](https://m.media-amazon.com/images/I/61YYf-pJOZL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: Clock speed? Chipset?** A: The chipset is in the description, it is the FTDI FT232rl, it is internally clocked so there is no easy way to know what it is set to. If it helps I have personally run this unit at 115Kbps **Q: The ESP8266 Wi-Fi chip uses 3.3 vdc. With switch set to 3.3 volts on the programmer can you directlyTx and Rx to the ESP chip without level shift?** A: Yes. I've been programming numerous ESP8266 versions with this. No level shifting required **Q: Can it be powered via vcc and via usb at the same time?** A: While I have never done it, I only use it to program pro minis, it should be fine as long as it is under 500 mah, matches the 3.3/5v and shares the ground. I still think it would be best to program it only under USB power if possible though. At worst the fuse is tripped but that's what it is there for. If you ordered from me and do this, let me know your results. If it damages your board, please get in touch to get a no cost replacement. **Q: Gave up. can anyone get this to work? even tried with term emulator and known=-good mcu.** A: I found these only sort ot work with usb3.0. You can read, but not write. Don't forget some coms require rx and tx to flip. Rx of ftdi to tx of device... like with uart. ## Frequently Bought Together - HiLetgo FT232RL Mini USB to TTL Serial Converter Adapter Module 3.3V/5.5V - 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 - EDGELEC 120pcs Breadboard Jumper Wires 10cm 15cm 20cm 30cm 40cm 50 cm 100cm Wire Length Optional Dupont Cable Assorted Kit Male to Female Male to Male Female to Female Multicolored Ribbon Cables --- ## 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.uy/products/263421889-hiletgo-ft232rl-ftdi-mini-usb-to-ttl-serial-converter-adapter](https://www.desertcart.uy/products/263421889-hiletgo-ft232rl-ftdi-mini-usb-to-ttl-serial-converter-adapter) --- *Product available on Desertcart Uruguay* *Store origin: UY* *Last updated: 2026-10-24*
