Twi-Hack — One device. USB-A male, USB-C male, and USB-A (female) with Full HID keystroke injection

 One device. USB-A male, USB-C male, and USB-A (female). Full HID keystroke injection — built for ethical hackers, pentesters, and educators.

Twi-Hack is a pocket-sized, open-source HID injection dongle built around the Raspberry Pi RP2350A MCU. It combines more CPU headroom, triple-port connectivity, and a microSD slot in a tiny, rugged package—designed for lawful research, classroom labs, prototyping, and responsible security testing. No display, no fluff — just fast, scriptable HID capability.

Twi-Hack Highlights

• Price: starting at £29 (early-bird Kickstarter pricing).
• RP2350A MCU — dual ARM cores for faster, more responsive scripting than many RP2040-class devices.
• Triple ports — built-in USB-A (male), USB-C (male), and USB-A (female) so you can plug into legacy and modern hosts without adapters.
• microSD slot — store scripts, payloads, and logs locally (tested with cards up to 512 GB).
• Primary scripting in Python — easy to learn, widely used; libraries and examples planned.
• Open source — firmware, libraries, schematics, and 3D files published after the campaign.
• Host powered — no battery, minimal size, simple compliance.
• Small, rugged form — injection-molded ABS planned for production; 3D-printed prototypes through R&D.

Sample (ethical) tasks you can script: automated login flows for test accounts, controlled reboot/shutdown of lab devices, launching authorized capture apps, copying logs to/from microSD, toggling test peripherals.

Twihack Full features & tech specs

MCU & Performance

• Raspberry Pi RP2350A — dual ARM cores for responsive execution and better multitasking than typical RP2040 boards.

Ports & Connectivity

• USB-A (male), USB-C (male), USB-A (female) — onboard, no adapters required.
• microSD slot — tested up to 512 GB.

Scripting & Tools

• Python primary (first-class examples).
• HID libraries & examples for other languages planned.
• Plug-and-play HID: works with Windows, macOS, Linux, and Android (where allowed).

Power & Enclosure

• Host-powered (no battery).
• Injection-molded ABS planned for production; 3D-printed prototypes used during R&D.

Openness

• After the campaign: firmware source, example payloads, developer libraries, PCB schematics, and STL enclosure models.

Status

• Hardware prototype complete. Firmware, tooling, and documentation actively in development.

Twi-Hack fills a niche: a compact, fast, and open HID tool designed for learning, authorized research, and rapid prototyping. The triple-port layout and RP2350A give it practical advantages over many tiny HID dongles: fewer adapters, better scripting performance, and a microSD-backed workflow for logs and payloads.

Twi-Hack is currently live on Kickstarter, with pledges starting from £29, and the campaign is already 512% funded — with 15 days remaining to back it and grab early rewards.
