 OEM BASIC Stamp Design and Modules Overview
The OEM modules are fully functional BASIC Stamp® microcontrollers. They are programmed using our Windows Editor just like any BASIC Stamp module you're able to see a variety of working models using easily obtainable through-hole parts. The smallness, compactness, and obscure complexity of a BASIC Stamp module can be very intimidating. Therefore, this larger and friendlier format of the OEM modules makes it easier to see and grasp the location/purpose of the individual components. If you embark on such an OEM design, it's important to know that Parallax technical/engineering support is behind you 100%. And now the pricing of the PBASIC Interpreter Chips starts as low as $8/chip at quantity 1! Once you discover the benefits of embedding a BASIC Stamp into your design you'll ask yourself why you didn't consider this path previously. is making it easier to embed a BASIC Stamp module into an OEM (Original Equipment Manufacturer) design. The BS2sx OEM Module (Assembled) is approach of making your own board to house BASIC Stamp components will save you considerable costs as opposed to using a 24-pin module but still offers the same desirable features including reprogrammability. BASIC Stamp Interpreter chips are available in a number of packages and the pin outs may be different so be sure to specify the correct package and use the correct pin out. Prior to embarking on your own OEM design, we recommend contacting Parallax technical support if you have any questions. The BASIC Stamp OEM Manuals will provide you with complete details.
The OEM modules are intended to serve as an example of building your own BASIC Stamp module. By offering a selection of BASIC Stamp OEM modules
What are the key benefits of OEM BASIC Stamp design?
- Improve time to market
- Reprogrammability and ease of use
- Save time developing with a well proven solution
- Cost savings; Embedding the components of a BASIC Stamp microcontroller costs but a fraction of the module itself.
As explained above, one of the main purposes behind the BASIC Stamp OEM modules
BASIC Stamp OEM Design Considerations
When designing a BASIC Stamp 2 module into your product, this is an overview of considerations:
 Power Supply
The BASIC Interpreter (also known as the PBASIC Interpreter chip-shown on the right) requires a regulated/well-filtered 5 Vdc supply. The LM2940 is a positive 5V regulator which was selected because of its wide operating range, built-in protection features, and ability to deliver up to 1 Amp of current. Be sure to consult the manufacturer's recommendations for input and output capacitance selection for the regulator that you will be using in your design
 Resonator Location
When laying out your board, please choose a location for the resonator that is as close as possible to the BASIC Interpreter, and has the shortest circuit traces possible to ensure reliable operation. For resonators, EEPROM, and the PBASIC Interpreter chips, click here. Parallax carries all of the parts that you need.
Regulatory Warnings
BASIC Stamp modules and their constituent components are not FCC approved because they are not in finished product form. If you wish to obtain FCC approval, you must first design the BASIC Stamp microcontroller into a product, then seek FCC approval of the whole product.
Serial Communication
Parallax uses a minimum complement of components to effect an interface between the high levels of RS232 and the relatively low levels of TTL. Regardless of how the line levels are interfaced, there are two important things to note: the idle state of the serial input line (Sin) at the interpreter, (RA.2), is high, so you may need to place a pull-up resistor on the RA.2 pin, also, there must exist some form of loop back from S-in to S-out so that the Stampw.exe software can communicate with the BASIC stamp.
 Powering up your OEM BS2. There are two mutually exclusive ways in which you can power your OEMBS2:
1)You may apply 6-24 Vdc to the Vin pin (and ground to the Vss pin) OR
2) You may apply 5 Vdc to the Vdd pin (and ground to the Vss pin)
The documentation includes a complete bill of materials with three sources and part numbers for each component. Please note that the lower power mode is only available when the regulator is removed and the BASIC Stamp is powered using Vdd.
