Preview - Stemma plug-n-play adapter for DS18B20's
one of the perks of working at adafruit is you get to request hardware - and you'll probably get fast turnaround! one of our adafruit.io dev's requested "an easy way to chain DS18B20 sensors for testing with adafruit.io's wippersnapper service" (https://learn.adafruit.com/using-ds18b20-temperature-sensor-with-wippersnapper) at 11:54am and after a few back-and-forth's we spun up this prototype idea.
you can use JST 3-pin cables (https://www.adafruit.com/product/4336) to 'chain' the adapters. then screw terminals mean you can easily connect DS18B20's in TO-92 (https://www.adafruit.com/product/374) or cable style (https://www.adafruit.com/product/381). there's a 4.7K signal pullup on board that can be disabled by cutting a trace, and a buffered signal LED that will let you know when there's data transmission on the 1-Wire line. prototype PCBs were ordered at 12:31pm, less than an hour from idea to booking!
