5912-ADA Adafruit SHT41 Trinkey - USB Temperature and Humidity Sensor
It's half USB Key, half temperature-humidity sensor, which is a PCB made to slip into any USB A port on a computer/laptop. On the board, the microcontroller ATSAMD21 is included. One pin of the microcontroller connects to a NeoPixel LED. Another pin is used as a capacitive touch input on the end. A reset button lets you enter bootloader mode if necessary.
