It is able to control and monitor timers, keypads, motors, sensors, switches, relays, lights, and more. Programming is performed in an easy-to-learn language called PBASIC, which is detailed in the starter kit that includes the BASIC Stamp 2, the [BASIC Stamp Discovery Kit](https://core-electronics.com.au/parallax-basic-stamp-discovery-kit-usb-27807.html). The BS2-IC is widely used in educational, hobby, and industrial applications. Plentiful resources including documentation, source code, and customer projects are available online and in print. **Features** - Processor speed: 20 MHz - Program execution speed: ~4,000 PBASIC instructions/sec. - RAM size: 32 bytes (6 I/0, 26 variable) - EEPROM (program) size: 2K bytes; ~500 PBASIC instructions - Number of I/O pins: 16 + 2 dedicated serial - Current draw @ 5 VDC: 3mA run, 50 µA sleep - Source/sink current per I/O: 20 mA / 25 mA - Source/sink current per unit: 40 mA / 50 mA per 8 I/O pins - PBASIC commands: 42 - Package: 24-pin DIP - Industrial-rated since Rev J **Key Specifications** - Power requirements: 5.5 to 15 VDC (Vin), or 5 VDC (Vdd) - Communication: serial (9600 baud for programming) - Dimensions: 1.20" x 0.63" x 0.15" (30.0 x 16.0 x 3.81 mm) - Operating temperature: -40 to +185 °F (-40 to +85 °C) **Getting Started** **Note:** If you are new to electronics and programming, Pololu recommend starting with the [BASIC Stamp Discovery Kit](https://core-electronics.com.au/parallax-basic-stamp-discovery-kit-usb-27807.html), an excellent introductory kit that comes with everything you need to get started with BASIC Stamp programming and electronics, including a BASIC Stamp 2 module, two printed booklets, and all the basic electronics components necessary to build dozens of fun projects. To get started with the BASIC stamp you will need the following: - Free [programming software](https://www.parallax.com/download/) that lets you type PBASIC programs in a text editor and compile them for downloading to your BASIC Stamp (the BASIC Stamp editors are available for Windows, Mac, and Linux). - Standard, straight-through serial cable for downloading programs from your computer to the BASIC Stamp. See the BASIC Stamp 2 schematic (143k pdf) for connecting the serial cable to the module. - BASIC Stamp manual (5MB pdf) - BASIC Stamp FAQ (110k pdf) - BASIC Stamp module (this product) - (Optionally, the Board of Education development board, which is included in the [BASIC Stamp Discovery Kit](https://core-electronics.com.au/parallax-basic-stamp-discovery-kit-usb-27807.html).) **Dimensions** | Size: | 1.2" x 0.6" x 0.4" | |---|---| | Weight: | 2.4 g | **General specifications** | Processor: | Microchip PIC16C57C @ 20 MHz | |---|---| | RAM size: | 32 bytes[1](https://core-electronics.com.au/#note1) | | Program memory size: | 2 Kbytes[2](https://core-electronics.com.au/#note2) | | Motor driver: | none | | Motor channels: | 0 | | User I/O lines: | 18[3](https://core-electronics.com.au/#note3) | | Max current on a single I/O: | 20 mA[4](https://core-electronics.com.au/#note4) | | Minimum operating voltage: | 5 V | | Maximum operating voltage: | 15 V | | Package: | 24-pin DIP | | Reverse voltage protection?: | Y | | External programmer required?: | N[5](https://core-electronics.com.au/#note5) | | Program execution speed: | ~4,000 instructions/second | | Supply current: | 3 mA[6](https://core-electronics.com.au/#note6) | | LCD included?: | N | **Notes:** 16 I/O, 26 variable2~500 instructions316 + 2 dedicated serial4the pins can sink up to 25 mA5A serial cable is required.6when running at 5 V; 50 µA in sleep mode **File downloads** - **BASIC Stamp Manual v2.2 (5MB pdf)** - **BASIC Stamp 2 Schematic (143k pdf)** - **BASIC Stamp Frequently Asked Questions (110k pdf)** - **What’s A Microcontroller?
