One side of the foam components look like this (these will be in a silver lined anti-static bag. Note that there should be ONE per LynxExpress kit you ordered):

This will have:
- 3 X 8 position LED displays
- 16 X MOC 3023 (optocouplers) chips
- 1 X PIC chip.
The MOC chips are 6 pin (not to be confused with the H11A1 Optocoupler transistor input - which is also 6 pin and on the other side). If in doubt about a 6 pin chip, look for the tiny print on the chip itself. it will either have 3023 (MOC) or H11A1 (the Octo trans input chip).
The other side will look something like this:

This has the following chips:
- 1 X LED Display driver chip (big chip)
- 2 X ST485BN line driver chips (8 pin chip)
- 1 X H11A1 Optocoupler transistor input chip (6 pin chip)
- 17 X 6 pin IC Sockets
I really think the only real area that could trip you up is if you mix the MOC chips and the H11A1 chips (as they are both 6 pin). Be careful.
