With a relay, three analogue channels, buffered inputs, and sinking outputs — all 24V tolerant — it packs serious control capability into a minimal footprint.\n\nUses the same Python library as the full-size Automation HAT, with automatic board detection. The library includes examples for reading analogue and digital inputs, switching outputs, and controlling the relay. Female header and broken-out pins require soldering.\n\nKey Features\n\n\n1× 24V @ 2A Relay – NC and NO terminals for high-side load switching\n\n3× 12-bit ADC (0–24V) – ADS1015 with ±2% accuracy\n\n3× Buffered Inputs – 24V tolerant digital inputs\n\n3× Sinking Outputs – 24V tolerant, up to 500 mA total across all three\n\n3.5 mm Screw Terminals – Secure, tool-friendly connections\n\nSPI Pins Broken Out – For additional peripheral connectivity\n\npHAT Form Factor – Compact size ideal for Pi Zero builds\n\n\nCompatibility\n\nRaspberry Pi 3B+, 3, 2, B+, A+, Zero, and Zero W\n\n\n\nWarning: Do not use to switch mains voltages!\n\n\nImportant Notes\n\nBuffered outputs switch on the ground side: 12/24V (supply) → load → output terminal → ground (supply)\nRelay should be switched on the high side (up to 2A)\nSinking outputs share a 500 mA total budget — a single channel can use the full 500 mA\nSoftware does not support Raspbian Wheezy\n\n\nIdeal For\n\nCompact smart home automation\nGreenhouse and garden monitoring\nPi Zero-based sensor and relay control\nIndustrial monitoring prototypes\n\n\nResources\n\nPython Library (GitHub)\nAutomation pHAT Pinout\n","vendor":"Little Bird","product_type":"physical","in_stock":false,"options":[],"variants":[{"id":7648,"title":"Default Title","sku":"PR-PIM214","price":25.75,"on_sale":false,"in_stock":false,"available_quantity":0,"option1":"Default Title"}]}
