It is compatible with Whats a Microcontroller , Robotics with the Boe-Bot, and most other Stamps in Class tutorials. See the Program Overview link at www.parallax.com/education for complete details. Features Key Specifications Built-in, surface-mount BASIC Stamp 2 Power requirements: 9 V battery BS2 microcontroller requires 7 mA running, 50 A in sleep BASIC Stamp I/O pins plus power Communication: USB mini-B to onboard connections are brought adjacent to a USB to RS-232 converter 2 x 1 3/8 breadboard. Operating temperature: 32 to 158 F Built-in 220-ohm series resistors (0 to 70 C) between the I/O pins and breadboard Dimensions: 3.05 x 4 in for a bit of protection in case of wiring (7.75 x 10.16 cm) errors Additional Items Required On-board regulator delivers up to 500 mA of current for BS2 and USB A to Mini-B cable ( 805-00006) breadboard circuits 9 V battery LED connected to the BS2s EEPROM PC running Windows 2K/XP/Vista/7 for clock line shows when a program is the BASIC Stamp Editor software. USB running drivers are included with the software Reset button installer which is a free download from 9 V snap-style battery clip with strain- www.parallax.com/basicstampsoftware relief holes to make it easy to strap the battery in place for mobile applications Grounded 0.125 in (3.18 mm) corner mounting holes, at 3.7 x 2.75 in (9.5 x 7 cm) on centers 4 peel-and-stick rubber PCB feet included Application Ideas BASIC Stamp-related homework assignments Dedicated science fair, contest, or hobby projects Affordable nodes in a BASIC Stamp 2 network Copyright Parallax Inc. BASIC Stamp HomeWork Board 10-pack ( 28158) v2.0 9/7/2011 Page 1 of 4 BASIC Stamp HomeWork Board Features 1. 9V Battery Clip: You can use alkaline or rechargeable 9-volt batteries. Disconnect the battery to turn off power to your board. 2. USB Programming Connector: This is a USB Mini B socket and USB to serial (RS-232) circuitry for programming and for two-way serial communication between the BASIC Stamp and your computer. The required USB drivers for Windows were included in the BASIC Stamp Editor software installer see the USB Drivers page at www.paralllax.com/usbdrivers for more information. 3. Voltage regulator: Supplies regulated 5 V, up to 500 milliamps with a 9 V battery. This supplies the BASIC Stamp and sockets labeled Vdd for circuits you will build on the breadboard area 4. Power header (X3): The sockets labeled (+5)Vdd connect to +5 VDC, (+)Vin connects directly to the power supplied to the board by the battery clip (+9 VDC typical), and (-)Vss connects to 0 V (ground). 5. Breadboard: The breadboard has metal clips that run underneath the white plastic board in a horizontal fashion. Each strip connects a 5-socket group, with two groups to each row, separated by a center trench. Wires or legs of components plugged into the same 5-socket group will be electrically connected. Components with many legs (such as pushbuttons or ICs), are placed in the middle of the board so that half of the legs are on the left side and half are on the right side of the trench. Note: Always disconnect power before building or modifying circuits 6. I/O Pin Access Header (X4): The BASIC Stamp module s 16 I/O pins, labeled 0 to 15, are connected to this header, so you can conveniently connect to your breadboard circuits. On this board, there are 220-ohm resistors placed between the header and the BASIC Stamp I/O pins to help prevent damage in case of a wiring mistake. 7. Reset Button: The reset button can be used to restart your BASIC Stamp without having to cycle the power. This saves wear-and-tear on the battery clip for simple program restarts. Some advanced programming techniques use the reset button and the BASIC Stamp EEPROM as a way to toggle between different program functions. Copyright Parallax Inc.
