Is the input voltage for HTU21D 3.3V? #1007

Closed jaeseok-park closed 8 years ago

jaeseok-park commented 8 years ago

The picture for HTU21D circuit shows that it can accept 5V Vcc. https://github.com/rwaldron/johnny-five/blob/master/docs/breadboard/humidity-htu21d.png

However, as the specification for it, the max input voltage seems to be 3.6V. https://www.adafruit.com/datasheets/1899_HTU21D.pdf

Could you fix the picture, please?

Thanks for the report!

jaeseok-park commented 8 years ago

@rwaldron The new picture uses analog pins instead of I2C SCL and SDA. Is it ok?

rwaldron commented 8 years ago

A4 and A5 are SDA and SCL

I didn't know it. Thank you. :-)
