Van anyone tell me the difference between the GY-30 and the GY-302 light intensity sensor?

Apart from the form factor and the pin layout, I cannot find any differences between the two.

I agree, I can't see any difference electrically by comparing the two spec sheets. And both of them seem to cross-reference to the same part - the BH1750FVI 

You've likely seen it already, but in case you haven't Sunfounder has a Wiki page that shows how to use the GY-30 with an Arduino Uno.

And BTW, welcome to the forum!

Thank you for your response.

I found a lot of pictures of the pin labels of the GY-30, but it took me a while to find a proper picture a GY-302.

Finally found one here:

The main difference is the pin layout.

GY-30 (left to right, hold the pcb with the pin labels on top)
GND
ADDR
SDA
SCL
VCC

GY-302 (left to right, hold the pcb with the pin labels at the underside)
ADDR
SDA
SCL
GND
VCC

Makes sense - looks like the GY-302 is laid out the same as a "sort-of-standard" I2C connector!
