Basically yes. The parts are generic and easy to find:
- Raspberry Pi Zero v1.3 (the version with no WiFi/BT is preferred; a Zero W works but has radios)
- Waveshare 1.3" 240x240 LCD HAT (the ST7789 model with the joystick + 3 buttons)
- a Pi Zero camera (OV5647) with the short Zero ribbon cable
- microSD card + a case (the open-source "Orange Pill" 3D print, or buy one)

Pitfalls:
1. Flash the SD card yourself. Don't trust kits that ship with a preloaded card.
2. Download only from the SeedSigner GitHub releases page, and verify the release's sha256 manifest and its PGP signature before you flash. The guide walks you through it.
3. Use the latest release that supports your board. Read the release notes for any Pi Zero 2 / other-board support before you buy anything else.
4. The display HAT pins only fit one way, and the camera ribbon goes contacts-toward-board. Most "it doesn't boot" problems come from those two.
Then test with a throwaway seed before you trust it with funds.
