🛠️ Hardware

Option 1: NARD flipper add-on

Buy it assembled at Red Team Tools, with or without SAM.

Or build it yourself from the files in the NARD repo.

Optionally 3d print a case designed by Antiklesys.

Option 2: Flippermeister

Buy it at Red Team Tools.

Option 3: Smart Card 2 Click

Buy HID SAM:

• Europe
• Canada
• eBay

Put SAM into adapter (because of chip on top) and plug into Smart Card 2 Click (Mikroe digikey with cheaper US shipping). Connect Smart Card 2 Click to Flipper Zero (See Connections below).
