CowJam:
Ages ago I picked up a 315Mhz transmitter (KXDJS2002.1) and receiver - these ones: http://www.geeetech.com/index.php?main_page=product_info&cPath=23&products_id=74

EDIT: Never mind, it's in one of the pictures on the link above. Rather than deleting this I'll leave it here in case anyone's googling for the same thing later.

It's GND, Dat1, Dat2 and Vcc starting from the nearest edge.

hi, I have the same transmitter, but the 433Mhz one. I have the same problem, and thank you for your "edit" :slight_smile:
but i don't understand if pin near the corner is Vcc or GND. Thank you!

I have the receiver (KXD10036) too but I don't know pins =(

EDIT:
i found it!
