A small computer module from Parallax, Inc., Rocklin, CA (www.parallaxinc.com) that provides an interpreter that runs the PBASIC (Parallax BASIC) programming language. The program is loaded into an EEPROM, and modules come in various sizes for integration into third-party products. The PBASIC interpreter chip is also available independently; for example, Microchip uses it in its PIC microcontroller products. See PIC.
