available for SMT parts currently available (except BGA) and applies simple point-to-point wiring to achieve a quick prototype circuit. The system removes the delay in layout, fabrication, and delivery of a custom PCB and provides a general platform on which almost any component can be mounted in many orientations. It can be considered “perf board for surface-mount.” The system consists of a simple grid of pads that is designed to accommodate all pin pitches available on various parts by having the user shift the device around at mounting time to find the best fit, then tacking the part down. This is followed by hand-wiring the inter-connects between parts with bare fine wire. The result is a small, tight neat package, utilizing SMT and through-hole parts if desired.

The series currently has four board choices which allow for different construction capabilities. All boards except the SMT-300 have different grid spacing on either side of the board for the best fit of components. The SMT-100 is a basic board, 2 x 3 inches, featuring a universal grid on which to mount parts; it’s intended for general prototyping of small to medium sized circuits. The SMT-200 features a set of large pads on the back of the board that can be used as a plane for convenient electrical connection (via holes through the board) or for heatsinking and mounting larger power components. The SMT-300 addresses the SMT and through-hole hybrid designs, combining 100 mil spaced through-holes which border two SMT universal grid areas. Additionally, this board can be used for building custom adapter boards from surface-mount parts for mating to solderless breadboard applications. The SMT-400 is a small mini board (just under one inch square) allowing for small “fix” or daughterboards to be constructed.

Smart 7. 5 KW Brushless DC Motor Controller Roboteq, Inc., introduces an intelligent controller capable of directly driving a brushless DC up to 150 amps at up to 50V. The BL1650 is targeted at designers of electric bikes or karts, mobile robots, or any other high power brushless motor control application.

The controller accepts commands from either analog pedal/joystick, standard R/C radio for simple remote controlled robot applications, or RS-232 interface. Using the serial port, the BL1650 can be used to design fully or semi-autonomous robots by connecting it to single board computers, wireless modems, or WiFi adapters.

The BL1650 incorporates a Basic language interpreter capable of executing over 50,000 Basic instructions per second. This feature can be used to write powerful scripts for adding custom functions, or for developing automated systems without the need for an external PLC or microcomputer.

The BL1650 uses the motor’s Hall sensors to measure speed and distance travelled with high accuracy. The controller can operate the motors in open loop or in closed loop speed, or position mode with a 1 kHz update rate.

The BL1650 features intelligent current sensing that will automatically limit the power output to 150A in all load conditions. The controller also includes protection against overheat, stall, and short circuits.
