- Number of I/O Pins: 16 + 2 dedicated serial
- Current Draw @ 5 VDC: 3mA run, 50 µA sleep
- RoHS compliant
The Parallax BASIC Stamp 2 Microcontroller Module serves as the brains inside of electronics projects and applications that require a programmable microcontroller. It can control and monitor timers, keypads, motors, sensors, switches, relays, lights, and more. The programming is performed in an easy-to-learn language called PBASIC.
The Parallax BASIC Stamp 2 Microcontroller Module is well-proven microcontroller with simple language. All vital components such as processor, clock source, memory and power regulator are provided on the BS2's tiny PCB. Connect it to power and it starts functioning. The projects that need small, permanent soldering area for circuitry may benefit from combining the BS2-IC with the BASIC Stamp 2 Carrier Board (#27120) or the Super Carrier Board (#27130). ). For low cost OEM solutions, the processor (PBASIC2 interpreter) and other components are available for integration to PCB.
The BS2-IC is widely used in educational, hobby, and industrial applications. It is strongly recommended for first-time BASIC Stamp users because of plentiful resources (documentation, source code, and customer projects) that are available online and in print. The Stamps in Class Educational Program was designed with this module that makes it a great place to learn about microcontrollers. Once you have become familiar with programming in PBASIC and have designed your own projects, you may want to explore our selection of BASIC Stamps with increased power, speed, or memory. For customers who require multi-processing or video generation capabilities, we recommend the Propeller microcontroller.

Refund Policy
If you are not satisfied with a product purchased from the Site, you may request a return within 30 days from the delivery date, unless the product is listed under the Return Exceptions below or is subject to specific return conditions noted on the product page.
This return policy also applies, as a minimum standard, to products sold and fulfilled by third-party vendors through the Marketplace.
Please review the Return Conditions, Return Exceptions and the process on How to Request a Return Authorization (RA) before initiating a return request.
European consumers exercising their statutory Right of Withdrawal are subject to different conditions. See the Statutory Right of Withdrawal.
Returns under this policy concern non-defective products. In the case of a confirmed manufacturing defect, remedies are handled under the Warranty terms, at the Vendor's discretion. See the Warranty section.
Return Conditions
To qualify for a refund under the 30-day return policy, all of the following conditions must be met:
- A valid Return Authorization (RA) number must be obtained prior to returning the product. Returns without an RA number will be refused.
- The RA number is valid for 30 days. The returned item must be received within that period.
- The RA number must be included with the return.
- Products must be returned in unused, unmodified condition (e.g., no scratches, alterations, missing parts, or signs of installation/use) and in their original packaging, suitable for resale.
- Shipping fees are non-refundable. Return shipping costs are the responsibility of the customer, except in cases of a product confirmed defective through RobotShop's troubleshooting process or of a verified shipping error by RobotShop.
- Refunds are processed within 7 days after receipt and inspection of the returned item.
- A €100 cleaning fee may apply to domestic robots returned in used or unclean condition.
- A 20% restocking fee may apply to large-quantity returns of items ordered specifically for the customer from the manufacturer or not part of RobotShop's standard inventory.
Return Exceptions
The following products are not eligible for return or refund under this policy:
- Used, damaged, or modified products — Items that show signs of use, wear, or alteration, making them unsuitable for resale.
- Consumables * — Use and wear-and-tear components, altered or depleted through use (e.g., batteries, belts, brushes, gears, filament, tires, disposable bags, lubricants, greases, waxes, etc.). Not eligible for return once opened or used.
- Perishables — Goods liable to deteriorate or expire rapidly. Not eligible for return.
- Sealed goods (health or hygiene) — Items sealed for health-protection or hygiene reasons (e.g., masks, gloves, odor-absorbing products). Not eligible for return once unsealed.
- Build-it-yourself products and items requiring customer assembly * — Including robots & kits, robot parts, and other products requiring assembly or soldering. Not eligible for return once assembled, soldered, or installed.
- Digital Goods, Software, and Apps * — Final sale only, due to licensing restrictions.
- Clearance Items * — Products identified as clearance or final sale, including end-of-life or discontinued items.
- Custom-made, personalized, or special-order items — Products manufactured, configured, adapted, or built to the customer's own specifications and requirements.
- On-Demand Items * — Standard catalogue products not stocked by RobotShop and ordered specifically to fulfill a customer request.
- Professional & Specialized Equipment — See the Professional & Specialized Equipment Warranty page and Professional & Institutional Buyers (B2B) section in the Terms & Conditions.
* European consumers retain their statutory Right of Withdrawal on these items. Its exercise is subject to the conditions and exclusions set out in the Statutory Right of Withdrawal, and any reimbursement may be reduced to reflect a loss in value resulting from handling beyond inspection.
How to Request a Return Authorization (RA)
While the same return policy applies, these orders require a separate contact process for returns.
- RobotShop Fulfilled Orders → submit a support ticket from your account under My Support Tickets.
- Marketplace Vendor Orders → submit a ticket from your account under My Marketplace Tickets to contact the vendor directly.
Note: Marketplace vendor products are normally labelled with SKUs starting with RM, and identified on the product page with the mention "Sold and fulfilled by [Vendor Name]".
