View Full Version : Not sure about the components

11-14-2009, 10:29 PM
I just bought a chip·basic stamp 2, it came with the basic stamp chip (BS2 Rev J) and the circuit board.
But I want to install the other components and I don't know exactly what they are.
In my circuit board I have "RP1 220" and "RP2 200". Can any one tell me what are they?
thanks in advance.

What 'circuit board' are you talking about? RP1 and RP2 are probably 220 ohm and 200 ohm (R)esistors but the schematic will tell you for sure.

The components are not resisters, they are IC components with 8 inline (serial) pins.
I will try to attach a picture

They are resistor networks like this one: www.jameco.com/webapp/wcs/stores/servlet/ProductDisplay?langId=-1&productId=108564&catalogId=10001&freeText=108564&app.products.maxperpage=15&storeId=10001&search_type=jamecoall&ddkey=http:StoreCatalogDrillDownView (http://www.jameco.com/webapp/wcs/stores/servlet/ProductDisplay?langId=-1&productId=108564&catalogId=10001&freeText=108564&app.products.maxperpage=15&storeId=10001&search_type=jamecoall&ddkey=http:StoreCatalogDrillDownView)

They're probably the ones with eight isolated 220 Ohm resistors.
