Overview
The TC2030-FTDI-C232HD-DDHSP-0 is FTDI's C232HD-DDHSP-0 Hi-Speed USB to UART cable with a 6-pin TC2030 Plug-of-Nails head. Its FT232H converter runs the UART at up to 12 Mbaud with 3.3 V signals, and pin 1 (VCC) is a 3.3 V output that can supply up to 250 mA. It suits a serial console, a UART bootloader download or fast logging on a 3.3 V board with no header fitted.
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.

Options
| Option | Choice | Detail |
|---|---|---|
| Head | Legged | Legs clip into leg latch holes in the PCB, so the cable holds itself in place (TC2030-FTDI-C232HD-DDHSP-0) |
| 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-C232HD-DDHSP-0) |

Pin Connections
| TC2030 Pin | FTDI Signal (Wire Colour) | Direction | Function |
|---|---|---|---|
| 1 | VCC (red) | Output | 3.3 V, 250 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 |
The CTS, RXD, TXD and RTS lines also carry the TMS, TDI, TCLK and TDO names in Tag-Connect's pin table for this cable.
The FTDI cable's other four lines (DTR, DSR, DCD and RI) are not connected to the TC2030 head. If your board needs DTR on pin 2 in place of CTS, see the TC2030-FTDI-C232HD-DTR.
Check your board's voltage: this cable is for 3.3 V boards. Its outputs (TXD and RTS) drive to about 3.3 V, and pin 1 is a 3.3 V supply output. FTDI's datasheet says the signal pins are 5 V tolerant, so the inputs (RXD and CTS) accept 5 V signals, but a 5 V board must read 3.3 V as a logic high. If your board has its own supply, leave the VCC pad unconnected. For 1.8 V logic, choose the 1.8 V version of the TC2030-FTDI-TTL-232RG.
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
Engineers who need a faster serial link than the 3 Mbaud TTL cables, on a 3.3 V board, with six pads on the PCB instead of a 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 |
| Board with a fast UART | High-rate logging or bulk data transfer | UART up to 12 Mbaud, four times the TTL-232R and TTL-234X rate |
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 | 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 (this cable) | 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-C232HD-DDHSP-0 | Legged | Development and debugging: clips in and stays connected hands-free |
| TC2030-NL-FTDI-C232HD-DDHSP-0 | 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.

Questions and Answers
-
What Is the Tag-Connect TC2030-FTDI-C232HD-DDHSP-0 Used For?
It gives a PC a 3.3 V UART link at up to 12 Mbaud to a board through six pads in the TC2030 footprint, with no header fitted. Typical jobs are a serial console, a firmware download over a UART bootloader, and fast logging or data transfer that a 3 Mbaud cable cannot keep up with.
-
Which Signals Are on the Six Pins?
Pin 1 is VCC (3.3 V output), pin 2 CTS, pin 3 RXD, pin 4 TXD, pin 5 GND and pin 6 RTS. RXD and CTS are inputs to the cable; TXD and RTS are outputs. The UART signals and VCC are all 3.3 V. The FTDI cable's DTR, DSR, DCD and RI lines are not connected to the head.
-
Can I Power My Board From the Cable?
Yes, if your board runs from 3.3 V. Pin 1 (VCC) is a 3.3 V output from the cable's own regulator, between 3.2 V and 3.6 V, and FTDI's datasheet gives a 250 mA maximum. If your board has its own supply, leave the VCC pad unconnected.
-
Can I Use It with a 5 V Board?
Only if the board reads 3.3 V as a logic high. FTDI's datasheet says the cable's signal pins are 5 V tolerant, so its inputs accept 5 V signals, but its outputs drive to about 3.3 V. Leave the VCC pad unconnected, because pin 1 is a 3.3 V output. For 5 V signals, choose the TC2030-FTDI-TTL-234X-5V, which runs at up to 3 Mbaud.
-
How Does It Differ From the TC2030-FTDI-C232HD-EDHSP-0?
The difference is the supply on pin 1. This cable gives 3.3 V at up to 250 mA from its own regulator; the TC2030-FTDI-C232HD-EDHSP-0 gives 5 V at up to 450 mA from the USB port. Both have 3.3 V UART signals, the same pinout and the same 12 Mbaud top rate. Choose this one when your board runs from 3.3 V.
-
How Does It Differ From the DTR Version?
On this cable, TC2030 pin 2 carries CTS, so RTS and CTS give hardware flow control. On the TC2030-FTDI-C232HD-DTR, pin 2 carries DTR instead, which some serial bootloaders use to reset the board or start a download. Choose the DTR version only if your board's design puts DTR on that pad.
