{"product_id":"m5stack-mini-proto-unit-40-hole-u064","title":"M5Stack Mini Proto Unit – 40-Hole Prototyping Board | U064","description":"\u003cp\u003eThe M5Stack Mini Proto Unit provides a compact 40-hole solderable board for custom sensor interfaces, signal conditioning, connector adaptation, level conversion, protection circuits, and one-off electronics prototypes. The HY2.0-4P Grove connection brings the selected host port’s power and signal pins into the Unit form factor, while two LEGO-compatible holes support mechanical integration. The board does not automatically add regulation, isolation, level shifting, current limiting, or protection; those functions must be designed and tested by the developer.\u003c\/p\u003e\u003ch2\u003eMini Proto Unit: Core Functions and Control\u003c\/h2\u003e\u003ch3\u003eBuild on a 40-Hole Solderable Area\u003c\/h3\u003e\u003cp\u003eThe perfboard provides space for through-hole components, small modules, passive networks, connectors, and point-to-point wiring.\u003c\/p\u003e\u003ch3\u003eBreak Out Grove Power and Signals\u003c\/h3\u003e\u003cp\u003eThe Grove connection exposes the selected host port, but exact voltage and GPIO mapping depend on the controller and port.\u003c\/p\u003e\u003ch3\u003eMount Compact Custom Circuits\u003c\/h3\u003e\u003cp\u003eTwo LEGO-compatible holes support fixtures and educational assemblies in the standard Unit footprint.\u003c\/p\u003e\u003ch2\u003eMini Proto Unit Applications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eCustom Grove sensor interfaces\u003c\/li\u003e\n\u003cli\u003eLevel shifting and signal conditioning\u003c\/li\u003e\n\u003cli\u003eConnector and pinout adaptation\u003c\/li\u003e\n\u003cli\u003eFilters, pull-ups, and protection circuits\u003c\/li\u003e\n\u003cli\u003eEducational soldering projects\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eHow to Integrate the Mini Proto Unit\u003c\/h2\u003e\u003col\u003e\n\u003cli\u003eIdentify the exact host port, voltage, GPIO mapping, current limit, and signal direction.\u003c\/li\u003e\n\u003cli\u003eDraw the schematic and layout, including power protection, decoupling, and connector orientation.\u003c\/li\u003e\n\u003cli\u003eAssemble low-profile components first and inspect every solder joint.\u003c\/li\u003e\n\u003cli\u003eCheck continuity, shorts, polarity, and resistance to ground with the host disconnected.\u003c\/li\u003e\n\u003cli\u003eUse a current-limited supply to verify every rail before connecting the controller.\u003c\/li\u003e\n\u003c\/ol\u003e\u003ch2\u003eMini Proto Unit Deployment Notes\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eExample pin mappings for one M5Core family do not apply to every host.\u003c\/li\u003e\n\u003cli\u003eNo regulation, isolation, level conversion, or overcurrent protection is included automatically.\u003c\/li\u003e\n\u003cli\u003eExposed solder joints require spacing, insulation, and a suitable enclosure.\u003c\/li\u003e\n\u003cli\u003eCurrent capacity and heat dissipation depend on the complete custom design.\u003c\/li\u003e\n\u003cli\u003eDisconnect power before soldering or rewiring.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eMini Proto Unit Development Resources\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/docs.m5stack.com\/en\/products\/sku\/U064\" target=\"_blank\" rel=\"nofollow noopener noreferrer\"\u003eM5Stack Mini Proto Unit Official Documentation\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/uiflow2.m5stack.com\/\" target=\"_blank\" rel=\"nofollow noopener noreferrer\"\u003eUiFlow2 Development Environment\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/docs.arduino.cc\/software\/ide\/\" target=\"_blank\" rel=\"nofollow noopener noreferrer\"\u003eArduino IDE\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LogicBoundless","offers":[{"title":"Default Title","offer_id":49240355012823,"sku":"LB-M5-U064","price":4.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/8952\/2135\/files\/1_97318d3e-42e7-4dfb-8e81-421a5659d613.jpg?v=1783243277","url":"https:\/\/logicboundless.com\/products\/m5stack-mini-proto-unit-40-hole-u064","provider":"LogicBoundless","version":"1.0","type":"link"}
