Hello Quattro,

The SX series chips are really handy little chips and are great for all sorts of projects.  They are fast, inexpensive, and fairly easy to use.  Using tools like the SX/B compiler and examples make a great way to start.  Although the Prop is a more powerful chip, the SX series has some advantages over the Prop and makes more sense to use for some projects.  Some of the advantages are:

- Fast startup time (doesn't need to load code from external EEPROM)
- 5v or 3.3v operation
- Inexpensive
- Code/firmware can be secured and protected int he chip.
- If you like Interrupts, you've got them.

I had a couple interfacing projects that the SX was ideal for ant that other chips wouldn't cut it.  One in particular excluded the propeller because of the latency involved in reading the code from the external EEPROM.  Each of the chips has their place and it's nice to have the SX as another option.

If you want to get started with them you may just want to get an SX-KEY and a couple of the Parallax Protoboards that Parallax offers (around $10 each).

If you want one of the SX48 chips in a small form factor that fits on a breadboard and also want to try out soldering the surface mount SX48 chip then you may be interested in one of the kits I offer as mentioned in the following thread:

The others on this forum that have tried the kit have had excellent results and had a chance to try something new.

One project I used it with was to try out some extra large 7-segment display panels that I am using to make a count down timer for robot events.  I used an SX28 for the final version but the DIP module helps with development.  Having the onboard RS-232 and extra EEPROM helps too.
