About these guides

MakerHub writes these guides from the questions our own customers ask on WhatsApp, Shopee and Lazada. Every wiring diagram is drawn against the exact module we stock, every code sample is compiled before it’s published, and every parts list links to a real SKU with a live Malaysian price. Guides are updated when a module changes or a customer finds a better way.
