Legs clip into leg latch holes on the board, so the cable stays in place hands-free. Best for development and debugging.
Fits a smaller footprint with no leg holes. For production programming and test fixtures, and for bench work when held with a TC2030-CLIP.

Key Features
Overview
The TC2030-FTDI-TTL-232R-3V3 is FTDI's TTL-232R-3V3 USB to serial converter cable with a 6-pin TC2030 Plug-of-Nails head in place of the usual header socket. It gives a PC a 3.3 V UART link to six pads on your board, so the board carries no serial connector.
Choose Legged or No Legs in the options above.
The Legged version clips into leg latch holes in the board and stays put while you work. The No Legs version fits a smaller footprint and suits production programming, test fixtures and bench work with a TC2030-CLIP.
Why Engineers Choose the Tag-Connect TC2030-FTDI-TTL-232R-3V3 USB to 3.3 V Serial Cable (Legged or No Legs)
3.3 V Serial Console
No Header on the Board
Legged or No Legs
A 3.3 V UART Link From Your PC to Six Pads on the Board
The TC2030-FTDI-TTL-232R-3V3 is FTDI's TTL-232R-3V3 USB to serial converter cable with a 6-pin TC2030 Plug-of-Nails head in place of the usual header socket. It gives a PC a 3.3 V UART link to six pads on your board, so the board carries no serial connector. The No Legs version is the TC2030-NL-FTDI-TTL-232R-3V3.
Options
| Option | Choice | Detail |
|---|---|---|
| Head | Legged | Legs clip into leg latch holes in the PCB, so the cable holds itself in place (TC2030-FTDI-TTL-232R-3V3) |
| Head | No Legs | No leg holes, so a smaller footprint; hold by hand, with a TC2030-CLIP, or mount it in a test fixture with a TC-MOUNT-6 bracket (TC2030-NL-FTDI-TTL-232R-3V3) |
Specifications
| Parameter | Value |
|---|---|
| FTDI cable | TTL-232R-3V3, with an FT232R converter inside the USB plug |
| UART signal level | 3.3 V |
| VCC on pin 1 | 5 V output from USB, 75 mA maximum |
| Data rate | 300 baud to 3 Mbaud |
| Handshaking | RTS and CTS |
| USB | USB 2.0 Full Speed |
| Operating temperature (FTDI cable) | -40 °C to +85 °C |
| Cable length | 1.8 m (5.9 ft) nominal |
| Drivers | FTDI VCP (virtual COM port) and D2XX drivers, free to download, for Windows 7, 8.x, 10 and 11, macOS 10.9 and later, and Linux 2.4 and later |
| In the box | Cable only. No retaining clip or fixture is included. FTDI's drivers are a free download. |
Pin Connections
| TC2030 Pin | FTDI Signal (Wire Colour) | Direction | Function |
|---|---|---|---|
| 1 | VCC (red) | Output | 5 V from USB, 75 mA maximum |
| 2 | CTS / TMS (brown) | Input | Clear to send handshake |
| 3 | RXD / TDI (yellow) | Input | Receive data, from your board's TX |
| 4 | TXD / TCLK (orange) | Output | Transmit data, to your board's RX |
| 5 | GND (black) | Ground | Ground |
| 6 | RTS / TDO (green) | Output | Request to send handshake |
Check pin 1: VCC on pin 1 is 5 V, even though the UART signals are 3.3 V. If your board runs from 3.3 V, leave the VCC pad unconnected or make sure your supply can take 5 V on it.
The CTS, RXD, TXD and RTS lines also carry the TMS, TDI, TCLK and TDO names that Tag-Connect uses across its FTDI range.
PCB footprint: the standard 6-pin TC2030 footprint. Tag-Connect publishes separate Legged and No Legs footprints; the No Legs footprint has no leg holes and takes less board space. Leave the contact pads free of solder paste and keep tracks and vias out of the keep-out area.
Spring-Pin Contacts
In Tag-Connect's cycle testing, its spring pins last for well over 100,000 operations.
Who It's For
Firmware and test engineers who need a 3.3 V serial console or bootloader link and want six pads on the PCB instead of a fitted UART header.
| Target | Task | Connection |
|---|---|---|
| MCU, FPGA or module with a 3.3 V UART | Serial console, log output and command line | TX, RX and GND, plus RTS and CTS if your firmware uses hardware flow control |
| MCU with a UART bootloader | Firmware download over the serial bootloader | The PC sees a virtual COM port, so the vendor's bootloader tool or a terminal program talks to it directly |
| Production test station | Serial test commands and calibration | No Legs head, held in a fixture with a TC-MOUNT-6 bracket, or a TC2030-CLIP on the bench |
Compare the FTDI Cables
Tag-Connect fits the same TC2030 head to several FTDI cables. They differ in signal level, what pin 1 does and data rate:
| Cable | FTDI Cable | VCC on Pin 1 | UART Signal Level | Data Rate | Pin 2 |
|---|---|---|---|---|---|
| TC2030-FTDI-TTL-232R-3V3 (this cable) | TTL-232R-3V3 | 5 V output, 75 mA | 3.3 V | 3 Mbaud | CTS |
| TC2030-FTDI-TTL-232R-5V | TTL-232R-5V | 5 V output, 75 mA | 5 V | 3 Mbaud | CTS |
| TC2030-FTDI-TTL-234X-3V3 | TTL-234X-3V3 | 5 V output, 450 mA | 3.3 V | 3 Mbaud | CTS |
| TC2030-FTDI-TTL-234X-5V | TTL-234X-5V | 5 V output, 450 mA | 5 V | 3 Mbaud | CTS |
| TC2030-FTDI-TTL-232RG-VIP | TTL-232RG-VIP | Input: your board supplies 1.8 V to 5.25 V | Follows your board's VCC | 3 Mbaud | CTS |
| TC2030-FTDI-TTL-232RG (VREG and VSW) | TTL-232RG-VREG1V8, VREG3V3, VSW3V3, VSW5V | 1.8 V at 100 mA (VREG1V8), 3.3 V at 250 mA (VREG3V3), 3.3 V at 50 mA (VSW3V3) or 5 V at 450 mA (VSW5V) | 1.8 V, 3.3 V or 5 V, by version | 3 Mbaud | CTS |
| TC2030-FTDI-C232HD-DDHSP-0 | C232HD-DDHSP-0 (FT232H) | 3.3 V output, 250 mA | 3.3 V | 12 Mbaud | CTS |
| TC2030-FTDI-C232HD-EDHSP-0 | C232HD-EDHSP-0 (FT232H) | 5 V output, 450 mA | 3.3 V | 12 Mbaud | CTS |
| TC2030-FTDI-C232HD-DTR | C232HD-DDHSP-0 or EDHSP-0 (FT232H) | 3.3 V at 250 mA or 5 V at 450 mA | 3.3 V | 12 Mbaud | DTR |
For UART up to 12 Mbaud with no separate converter cable, see the TC2030-CIC-FT232H Chip-in-Connector, which has the FT232H inside the connector head.
Compare the Versions
| Part Number | Head | Best For |
|---|---|---|
| TC2030-FTDI-TTL-232R-3V3 | Legged | Development and debugging: clips in and stays connected hands-free |
| TC2030-NL-FTDI-TTL-232R-3V3 | No Legs | Production programming and test fixtures, or bench work with a TC2030-CLIP; smaller footprint |
Both versions use the same FTDI cable and pinout; only the head differs.
