Arduino Accessories

Stackable headers give reliable mechanical and electrical connections, keeping a low profile while providing enough clearance for connectors and allowing multiple shields or boards to be stacked securely. USB‑to‑Serial adapters simplify programming and communication, offering selectable voltage levels and auto‑reset pins that streamline firmware uploads without extra wiring. Compact data‑logging modules record serial streams directly to microSD cards, handling sensor and GPS data in ready‑to‑use formats and eliminating the need for custom storage code. Small OLED‑based display boards let a microcontroller’s output be visualised on‑board, supporting rapid debugging and user feedback. All of these accessories share a common focus on plug‑and‑play compatibility, robust construction and straightforward integration with Arduino‑compatible platforms.
