New question on the OEM BS2

bsparky

The files that Chris posted on the OEM-BS2, some of the pin outs on the PIC differ from the pin out from the schematic of a BS2-IC module.
I bought a BS2 interprater chip from Mouser p/n 619-PBASIC2CI/SS but I can't seem to find any documentation on this chip. The pins right off that I found wrong were the SDA , SCL , RX, and TX pins seem to be off by one. Can any one help me with the proper pin out for this chip. These are the 2 files in referance. Thanks

The schmatic you posted is for the BS2 OEM, where the PIC16C57 is a DIP package. You ordered a surface mount version of this chip and the pinouts are different. See the schematic for the BS2 module, which uses the surface mount version of the chip www.parallax.com/detail.asp?product_id=BS2-IC

OK so the PDF file I supplied is the right one to use for the pin out, right?

The OEM BS2 schematic attached to your message looks like it's for the DIP (thru hole) chip.

Well I attached to files to my post the picture is the thru hole I think you are refering to but I also attached a PDF file which looks like the one you linked to. Thanks for the replys. Just wanted to be sure before I make a board and solder them on, wouldn't even want to think about solder sucking them off if its wrong. Be my first time soldering SMD devices. Thanks

Forrest

Sorry, didn't see the second attachment on your post. Use the BS2RefF schematic.

Thanks for your patience Forrest. Will try to make a board tomorrow.

Replied to the wrong thread...Apparently there are two...
