BS2sx BULK (Homemade BS2sx Project)
October 8, 2010
Since the price for the BASIC STAMP microcontroller line is very pricy, I have decided to create my own BASIC STAMP OEM Design. It is the same circuit as the BS2sx but will cost under $20.
BASIC Stamp 2SX OEM Module Kit
This kit enables me to program the PBASIC interpreter chip and EEPROM chip (both are DIPs)
This kit contains the following.
- PC board
- PBASIC2sx Interpreter
- 16 Kbyte EEPROM
- 50 MHz resonator
- DB-9 serial connector
- 5-volt regulator, resistors, transistors, sockets and SIP pins
Some of the features of this kit are:
- Assembled form factor is a 20-pin SIP (0.1" spacing).
- PC board includes labeled component locations with visible traces between parts.
- PBASIC interpreter and EEPROM chips are socketed to allow easy replacement.

All in all, this will make a nice programing board
My Design is quite similair to this. Except that the I/O pins connecting to the serial connector won't be connected to anything. And instead of pins, I will use terminal blocks for easy hook ups for experimentation and for robotic use.

- 10 uf electrolyte capacitor
- 10k ohm resistor
- 220 ohm resistors
- terminal blocks
- Solderable Breadboard
- DIP sockets
However, this is still in the designing phase. I hope to have a fully capable microcontroler soon, and to be able to incorperate it in many of my project.
