This is my opinion on the Main Differences...
PIC .. not as easy to learn
Stamp.. too easy... your not a developer if you use this in my opinion
PIC... Lots of options
Stamp...Limited options
PIC.. like making a cake from scratch!!!
Stamp... Like buying box cake...
With a PIC you have more control over every single thing meaning you can personalize it more and also doesnt cost $$$...
Stamp cost so much because of their software and already prebuilt hardware...
Look at this stamp module:
**broken link removed**
$75 OMG!!
The Specs:
* Processor Speed: 8 MHz Turbo
* Program Execution Speed: ~6,000 PBASIC instructions/sec.
* RAM Size: 38 Bytes (12 I/0, 26 Variable)
* Scratch Pad RAM: 128 bytes
* EEPROM (Program) Size: 16 x 2 KBytes; (16 K for source; ~4,000 PBASIC instructions)
* Number of I/O Pins: 16 + 2 dedicated serial
* Current Draw @ 5 VDC: 15mA Run, 150 μA Sleep
* Source/Sink Current per I/O: 30 mA / 30 mA
* Source/Sink Current per unit: 60 mA / 60 mA per 8 I/O pins
* PBASIC Commands: 61
* Package: 24-pin DIP
* Commercial-Rated since Rev. B
Ok what you see in
BOLD sucks!
8Mhz is fine for most things but at $75 no! no!
The 6,000 instructions/sec sucks! i can get about 2,000,000 with a cheap 8mhz pic.
Ram, EEPROM (for $75 this sux!)
The package is always DIP what if you wanna make something small? or want to use batteries? you are limited a lot there. Here is a nice cheap PIC with way more features:
Now look at this DIP IC:
PIC18F46K20
This is about $4 and its like god compared to that $75 stamp..
Need less pins ...
PIC18F26K20
Same thing smaller pinout.

EVERYTHING IS BOLD REALLY! heh
Look at the ram and speed and power it needs and has compared to the stamp. You can make a board for this or with this for like $10 . hece you can have about 7 of these made into stamp type products for the same price of
1 slow stamp!
