Description: This graphic shows the proposed approach for a PCB that will interface external microphones via either XLR or 1/8 inch input jack to a stereo mini-jack connector for connection via a cable to a DSLR camera input. It also provides for volume control and a stereo output jack for connection to stereo earphones.

Sample Type: Powerpoint Document
File Size: 165.5K
Description: This schematic shows one of our microcontroller (MCU) designs for a flow meter and valve actuation system that was captured into a printed circuit board layout. It is a low powered design that will operate from 4 each NiMh AA batteries for a lifetime of over one year by making judicious use of SLEEP mode operations in the programming. The program for this microcontroller was generated in compiled PICBasic PRO in only 453 words.

Description: This 4-layer surface mount PCB included a battery powered microcontroller to measure the liquid flow from a flow meter and to turn on-off an external valve, including provision for wireless operation which required a special design of the ground plane layout for RF operations. 2 each prototypes were produced for less than $300, including all initial non-recurring tooling cost. In volume the board will be less than $20 each. Extra design effort to select components minimized production cost.

Sample Type: Acrobat Document
File Size: 88.94K
Description: This is the schematic for a microcontroller for a CS Generator that included generation of a 5 Hz signal output, a timer circuit, and interfaces to relays that were used to turn on-off the motor. It was designed for battery power and included an option to operate the motor by RF wireless control.
