Key Features
Overview
The Tag-Connect TC2030-FTDI-TTL-234X-3V3 combines FTDI’s TTL-234X-3V3 USB-to-UART cable with a TC2030 6-pin “legged” Plug-of-Nails™ connector. It provides 3.3 V-level Tx/Rx plus RTS/CTS hardware handshaking, VCC (5 V pass-through) and GND on a tiny footprint, eliminating the need for a mating header on your PCB.
The “legged” TC2030 latches into dedicated holes for a secure, hands-free connection during programming, bootloader access or serial debug. Using the FT234X-based cable ensures robust USB driver support across major operating systems and a standard 1.8 m lead for bench flexibility.
This cable is part of a wider family, including 5 V logic options and “no-legs” (NL) variants for use with a retainer clip. See our USB/Serial Tag-Connect Cables catalogue for related models such as the TC2030-FTDI-TTL-234X-5V and NL versions.
Engineers choose TC2030 to reduce BOM and reclaim board area while maintaining reliable test/programming access. If you need a compact, repeatable way to reach a UART console or bootloader on densely packed designs, the TC2030-FTDI-TTL-234X-3V3 is a practical, proven solution.

Frequently Asked Questions
Have a Question?
-
Does Debug Store stock related Tag-Connect cables and accessories?
Yes—see our Tag-Connect USB/Serial catalogue for 3.3 V/5 V and legged/NL options.
-
How does this compare with using a full-size debug header or a test fixture?
It achieves similar access with a fraction of the board area and without expensive fixtures, improving serviceability.
-
How durable is the TC2030 connection for development use?
For extended sessions, use the legged version or the NL version with a clip to keep contacts stable.
-
What if my design uses 5 V logic levels?
Choose the 5 V variant in the same series (e.g., TC2030-FTDI-TTL-234X-5V) listed in our catalogue.
-
Can I power the target from the cable?
VCC (5 V from USB) is present; whether you can power the DUT depends on your design’s power path and current needs.
-
Is hardware flow control supported?
Yes. RTS/CTS are available for reliable, high-throughput transfers when your firmware enables them.
-
Which signals are available on this cable?
Tx, Rx, RTS, CTS, plus VCC (5 V from USB) and GND on the six TC2030 contacts.
-
How does the “legged” TC2030 differ from the “No-Legs” (NL) version?
The legged plug latches into holes for hands-free use; NL requires a clip/retainer for long sessions.
-
What is the Tag-Connect TC2030-FTDI-TTL-234X-3V3 used for?
It provides 3.3 V TTL USB-to-UART access to your PCB via a TC2030 footprint for programming, bootloader and serial debug.
