BASIC Stamp 2pe Motherboard provides a compact, professional-grade platform for BASIC Stamp applications. With the MoBoStamp-pe and the coming assortment of plug-in daughterboards, you can integrate and package one-off or multiple application systems with ease.
The MoBoStamp-pe has a footprint of less than four square inches. It includes a USB interface for programming and debugging from an attached PC. This USB interface is also capable of powering the motherboard, obviating the need for a separate power supply while connected to a computer. For portable applications, provision has been made for an external power source and for powering the system through an attached daughterboard.
Interface to the outside world takes place through the two daughterboard sockets. Plug-compatible daughtercards can handle interfacing, data acquisition, and sensing functions. The currently-available PWR-I/O-DB card provides an interface for up to six Parallax serial (three-pin) devices and/or servos, and provides separate voltage regulation and filtering for them. Watch for future cards that enable robot navigation and that provide environmental sensing, optical detection and measurement, LED displays, network connectivity, and programmable logic controller (PLC) interfacing, to name just a few.
Each motherboard also includes two user-programmable Atmel AVR microcontrollers: one for each of the daughterboard sockets. These microcontrollers act as coprocessors to offload compute-intensive and background tasks from the BASIC Stamp, yielding a high performance level while retaining the BASIC Stamp's legendary ease of programming. Both AVRs come preprogrammed with firmware for digital I/O, pulse-width modulated output, analog input, and frequency measurement.
