Ways to get hardware¶
PiWalletSV is designed as a DIY cold-wallet stack: download signed firmware, flash a microSD, and assemble the Pi + screen + camera yourself. That is the default path — especially while Raspberry Pi boards are hard to buy.
There are two devices:
- Zero — Raspberry Pi Zero W with the Adafruit 1.3 inch screen, joystick, and A/B buttons.
- Pro — Raspberry Pi 3 Model B with the Waveshare 3.5 inch touch screen.
Both run the same signer, use the same seeds, and pair with the same companion app. Ready to buy a limited batch instead? See the shop.
Batch status¶
Beta — limited quantities of Zero and Pro kits when offered. Follow @PiWalletSV on X for announcements.
Raspberry Pi supply¶
Raspberry Pi boards (especially Pi Zero / Zero W) are in very low supply right now. Memory and fab capacity are heavily pulled toward AI and datacenter demand, so distributors often show long lead times or empty shelves.
We do not currently sell Raspberry Pi Zero 2 kits — those boards are unobtainable at a reasonable price. Zero kits use Pi Zero W; Pro kits use Pi 3 Model B.
What that means for you:
- Full pre-assembled kits are offered only in small batches when boards are available at a sane price — not as always-in-stock inventory.
- Most builders should plan to source their own Pi, screen, and camera and flash from GitHub Releases (Download links there).
- Ask @PiWalletSV on X for current kit or case availability before ordering.
Three paths¶
1. DIY (default)¶
Bring your own parts, flash the official image, print or buy a case.
You need:
| Part | Notes |
|---|---|
| Raspberry Pi Zero / Zero W / Zero WH | 32-bit pi0 image; solder header if needed |
| Adafruit 4506 bonnet | 240×240 TFT, joystick, A/B buttons |
| ArduCam OV5647 + cable | Kit camera; not Camera Module 3 |
| microSD 8 GB+ | Blank; you flash firmware |
| 5 V power + micro-USB cable | Right port = power only |
| micro-USB OTG adapter + USB stick | Optional — left port only; export/import vault during upgrades (see User manual) |
| Case | Print yourself or buy case-only |
| Part | Notes |
|---|---|
| Raspberry Pi 3 Model B | 64-bit pro-pi3 image |
| Waveshare 3.5 inch LCD (F) | 320×480 capacitive touch; plugs onto the 40-pin header; comes with its mounting screws |
| ArduCam OV5647 + cable | Kit camera; not Camera Module 3 |
| microSD 8 GB+ | Blank; you flash firmware |
| 5 V, 2.5 A power + micro-USB cable | Pi's micro-USB power port |
| USB stick | Optional — any of the four USB ports, no adapter; export/import vault during upgrades (see User manual) |
| Case | Print yourself or buy case-only |
Steps:
- Open Download → get the signed image for your board from GitHub Releases
- GPG + SHA-256 verify (Security § Release key)
- Flash with Raspberry Pi Imager — see Flash and first run
- Assemble and complete first boot (User manual)
Or build from source: Getting started / Build & deploy.
2. Full kit (limited batches)¶
When offered, a complete kit includes:
- Raspberry Pi Zero W (header soldered), heat sink, bonnet, OV5647 camera
- Factory-flashed microSD + SD adapter (full-size)
- 5 V adapter, power cable, printed case, kit insert
Optional (not in the box): a micro-USB OTG adapter and USB flash drive for the left micro-USB port — only for USB backup during upgrades. You do not need them for normal daily use.
- Raspberry Pi 3 Model B, Waveshare 3.5 inch touch screen, OV5647 camera
- Factory-flashed microSD, installed
- 5 V power adapter, USB cable, printed Pro case, kit insert
- The extra hardware and manuals that come with the Pi parts
Optional (not in the box): a USB flash drive for any of the Pi's USB ports — only for USB backup during upgrades. You do not need it for normal daily use.
You still need: a USB microSD reader/writer on your PC or Mac to re-flash before you fund (strongly recommended).
The included card is flashed and boot-tested at the factory. We run diagnostics on the assembled kit and test the display, camera, controls (joystick and buttons on the Zero, touch on the Pro), and software checks before shipment. Because that process writes logs and other state, the shipped card no longer byte-matches the pristine release image and cannot be validated with a whole-image checksum.
You may accept the tested card as shipped, but that relies on the factory
and delivery chain. For proper cold-wallet assurance, verify the signed
download and re-flash the card yourself before funding. The checksum
still verifies the downloaded .img.xz; re-flashing writes that verified
release to your card. Pi hardware has no secure boot.
Printable inserts for full-kit boxes (Zero and Pro): Printables.
3. Case only¶
Already have the Pi stack? Buy a printed case from the project instead of printing it yourself (PETG recommended for self-print):
- Zero case — tub, lid, and button caps; print from
hardware/case/. - Pro case — one piece; the screen is the lid and uses the screws that
come with it. Print from
hardware/pro-case/.
