Each breakout includes screw terminal blocks for direct connection of DS18B20 sensors in TO-92 or waterproof cable form — no soldering required.\n\nChain multiple extenders together using 3-pin JST PH cables to build a multi-point temperature monitoring network. Each board includes a 4.7K pull-up resistor (with a cuttable trace to disable) and a buffered signal LED that blinks red during 1-Wire data transmission.\n\nKey Features\n\n\nChainable Design – Daisy-chain multiple extenders with STEMMA JST PH 2mm cables\n\nScrew Terminal Blocks – Connect DS18B20 sensors (TO-92 or cable style) with just a screwdriver\n\n4.7K Pull-Up Resistor – On-board pull-up with cuttable trace to disable when not needed\n\nSignal LED – Buffered red LED blinks during 1-Wire data transmission for easy debugging\n\nSTEMMA JST PH 2mm Connectors – Standard 3-pin connectors for easy, solderless chaining\n\n\nCompatible Sensors\n\nGravity DS18B20 Temperature Sensor\nOctopus Waterproof DS18B20 Temperature Sensor\n\n\nIdeal For\n\nMulti-point temperature monitoring systems\nEnvironmental and IoT sensor networks\nQuick prototyping with DS18B20 sensors\n\n\n\nNote: This board is an adapter/extender only — DS18B20 sensors and JST PH cables are sold separately.\n\n\nPackage Contents\n\n1× Adafruit Chainable DS18B20 Extender Breakout\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":1011,"title":"Default Title","sku":"AF-5971","mpn":"ADA5971","price":8.74,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":100,"option1":"Default Title"}]}
