Our Professional Development Board (PDB) is a high-quality, fully-integrated development platform for BASIC Stamp and SX28AC/DP microcontrollers. A wide variety of typical I/O (LEDs, LCD interface, buttons, etc.) devices and circuitry are built into the PDB, providing the developer with an ideal platform for rapid microcontroller project development.

Features:

40-pin DIP socket (for all BASIC Stamp 24/40-pin and Javelin Stamp modules)
14-pin SIP socket (for BS1-IC)
28-pin “skinny” DIP socket (for SX28AC/DP)
2.1 mm, center-positive connector for DC power
16 discrete blue LEDs
Five blue 7-segment (with decimal point), common-cathode LED displays
Parallel LCD (available separately) may be configured in 4-bit or 8-bit mode
Two servo-compatible headers
Two 10KΩ potentiometers
Audio amplifier with built-in speaker; with switch for external speaker
L293D high-current driver for motors, solenoids, etc.
Eight, normally-open pushbuttons (I/O lines protected, and pulled-up to Vdd via 10KΩ)
Eight DIP switches (I/O lines protected, and pulled-up to Vdd via 10KΩ)
Pulse generator with selectable frequency (1 Hz, 10 Hz, 100 Hz, or 1 kHz)
RJ-11 connector; configurable for X-10 and 1-Wire® communications
RS-232 DCE port with MAX232E transceiver
DS1307 (I2C®) real-time-clock with 3v back-up battery (pre-installed)
