ChipShelf — IoT Parts Catalog

ChipShelf is a practical offline catalog for makers and students who need to recognize common IoT boards and modules — and understand what they are for — before buying or wiring. Browse 143 parts: 21 boards (ESP32 family, Arduino references, Raspberry Pi Pico W, Raspberry Pi 4 Model B, and more) plus 122 everyday modules (sensors, displays, drivers, basics). Each part shows a short use, when to use it, warnings, common mistakes, related parts, and identify tips. Pin maps and host-role wiring notes help you scan connections on the bench. Do more on the bench: • My shelf — mark parts you already own and filter the catalog • Compare boards or modules side by side (Wi‑Fi, BLE, logic level, buses) • Voltage / logic-compat hints when pairing a module with a host board • Companion kit suggestions (breadboard, jumpers, level shifter when needed) • Pre-plug checklist and a recognition quiz • Assembly guide — curated recipe combos (free sample included); Premium unlocks full recipes and local history Workshop-style UI with sticky filters, section jump on detail (warnings, pins, flash, checklist), Light / Dark / System appearance. Built for real bench work, not a week-by-week curriculum. Content ships offline with the app. ChipShelf does not teach mains / 220V wiring. Gas-sensor demos are low-voltage learning only and are not fire-safety certified equipment. Optional Remove Ads purchase; ChipShelf Premium is an auto-renewable subscription for Assembly guide + ad-free while active.
