Hardware: Parts list & Wiring

This page lists the hardware used in the Pika‑pika project and provides example shopping links for convenience. These links are examples only — verify part specifications and local availability before buying.

Safety first: Do not connect to mains without proper isolation and a fuse. If you are unsure, use an isolation transformer or certified commercial sensor modules.

Parts list

• Waveshare 2" SPI LCD / ST7789 (optional) — show QR code and status on-device

• 5 V power supply (capable of providing at least 2 A for Pi + peripherals)

• microSD card (16 GB or larger, class 10 recommended)

• Jumper wires and breadboard / small prototyping accessories

• Enclosure and inline fuse for mains safety (if you are building a mains-connected measurement device)
