Add to wish list

With the Parallax PBASIC1/P Build your own BASIC Stamp 1 with this through-hole (DIP) interpreter chip and other standard parts. 

All the control and ease of programming that you have grown to appreciate in the BASIC Stamp 1 module (#BS1-IC) is available with this chip and a few other components. Recommended for high volume applications or those with limited PCB real estate, the BASIC Stamp 1 interpreter chip can be used on your own PCB as an OEM solution. 

The three main components needed to build your own BASIC Stamp 1 are: 1) this PBASIC Interpreter Chip, 2) an EEPROM, 3) and a resonator; see Related Products.

We also offer the interpreter chip in a surface mount package (#PBASIC1XT/SS).

Product Features:
