Microcontrollers
How to choose microcontrollers
Build level
Pick a bare chip (Semiconductors) for full control, or a finished board (Circuit Boards & Components) for quick use.
Package style
Package size matters: DIP and SOIC8 are hand-solderable, while QFN48 needs hot air tools.
Connectivity
Choose a plain MCU or a wireless module (Electronics) based on need for remote access versus current draw.
Housing
Material and colour affect enclosure choice, with black or blue plastic hiding scratches better than bare FR4.
User level
Match the tier to skill, as graphical programming boards suit classrooms while ASIC tiers suit dedicated mining rigs.
What's good
- Bare semiconductor chips (the Semiconductors sub-type) let you design a custom board around a precise 8-bit or 32-bit core.
- Ready circuit boards and components, such as compact USB-C microcontroller boards, get a project running the same day.
- Electronics modules with wi-fi or bluetooth add wireless control without extra wiring.
- Low-power 8-bit parts suit battery sensors, trading speed for months of uptime.
Things to watch
- Loose chips need soldering kits and supporting parts, so they frustrate first timers.
- Small footprint boards save space but often drop expansion pins, limiting later add-ons.
- Specialist electronics like hash boards or camera boards serve one task and nothing else.
- Wireless modules draw more current than a plain chip, hurting long battery life.
Care & maintenance
Cleaning
Wipe FR4 and plastic boards with a dry cloth to stop dust bridging contacts.
Storage
Keep semiconductors in anti-static packaging, as gold or lead pins bend if knocked.
Environment
Store spare modules away from damp to protect metal connectors.
