BASIC Stamp 1 Serial Adapter

  • 27111 BASIC Stamp 1 Serial Adapter
Product ID: 27111
In Stock: 70


The BASIC Stamp 1 Serial Adapter provides serial port based programming capability from a PC running Windows to a BASIC Stamp 1. The BASIC Stamp 1 microcontroller has been around since the early 1990s and was designed to be programmed from a parallel port on a DOS-based PC. Since then, PC technology has evolved greatly so the BASIC Stamp 1 Serial Adapter was designed to program the BASIC Stamp 1 via a PC's serial port using the Windows-based BASIC Stamp Editor.  One end plugs into a serial cable and the other onto a 3-pin header provided on BASIC Stamp 1 development boards.

Key Features:

  • Easy interface between serial ports and the BASIC Stamp 1
  • Supported by the BASIC Stamp Editor (Windows)
  • Works with the Parallax USB to Serial (RS-232) Adapter (#28030)
  • Provides downloading and debugging capability


  • Male DB9 to male 3-pin header adapter
  • Voltage requirements: Powered by PC serial port (RS-232 powered)
  • Current requirements: n/a
  • Communication: RS-232C to TTL
  • Dimensions: 1.65 x 0.70 x 0.4 in (4.19 x 1.78 x 1.02 cm)
  • Operating temp range: +32 to +158 °F (0 to +70 °C)

Note: BASIC Stamp 1 debugging operates in a single direction only (BS1 to PC).  Additionally, the BASIC Stamp 1 Serial Adapter cannot be used to transmit and receive serial data via the BASIC Stamp's SERIN/SEROUT commands.
