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.

Questions and Answers
-
Can I Power the Target From the Cable?
Possibly. VCC (5 V from USB) is present on pin 1, and Tag-Connect rates it at 450 mA maximum. Whether it can power your DUT depends on your design's power path and current needs.
-
What If My Design Uses 5 V Logic Levels?
Choose the 5 V variant in the same series, such as the TC2030-FTDI-TTL-234X-5V.
-
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.
-
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.
-
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.
-
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.
-
Which Signals Are Available on This Cable?
The six TC2030 contacts carry Tx, Rx, RTS, CTS, VCC (5 V from USB) and GND.
Pin Signal 1 VCC (5 V output) 2 CTS 3 RXD 4 TXD 5 GND 6 RTS Watch the supply pin. VCC really is 5 V on this cable, although the UART signal level is 3.3 V. -
Is Hardware Flow Control Supported?
Yes. RTS/CTS are available for reliable, high-throughput transfers when your firmware enables them.
-
What Driver Support Is Available?
It uses an FTDI FT234XD USB-UART bridge with widely supported Windows, macOS and Linux drivers.
