# Tigard (SecuringHardware.com)

> A universal hardware-hacking interface: UART, JTAG, SWD, SPI and I²C over one USB-C connection, with level shifting from 1.8 to 5.5 V.

- **Category:** Instruments
- **Availability:** Preorder
- **Price:** US$49, checked 2026-09-18
- **Good for:** Talking to a board over whichever protocol it exposes, without a drawer of adapters.
- **You'll need:** A host computer and wiring to the target.
- **Trade-off:** No radio; it is a wired interface tool.

## Blueprint

**Open hardware.** Tigard is fully open hardware: a complete KiCad project (schematic, PCB, footprints, 3D STEP models) is published under CC-BY-SA 4.0.

### Key parts

| Part | Role | Datasheet |
|---|---|---|
| FTDI FT2232HQ | Dual-channel USB-to-UART/MPSSE (JTAG/SPI/I2C) bridge |  |

_Notes:_ Confirmed via gh api (repo tree + LICENSE.txt = CC-BY-SA 4.0, 877 stars). No separate BOM file found in-repo, but the KiCad project itself carries part values. FTDI's own datasheet/product pages (ftdichip.com) returned 403 to automated fetches in this environment, so no manufacturer datasheet URL is included.
