Were looking for someone that can Design a Keypad electrode matrix connected to a QT60240
Low battery consumption, smallest components compact, small dimension PCB board.
Firmware will be simple for this first prototype.
List of components:
PIC: You can use, atmega88V, atmega128, or atmega168V [url removed, login to view]
Flash Memory: Atmel Smallest available. [url removed, login to view]
Touch Decoder: Atmel QT60240 [url removed, login to view]
Touch sensitive switch pads/capacitive touch pads: Custom fit size for plastic/rubber/metal inner key tip.
Example: [url removed, login to view] or any adhesive thin flexible plate available on the market.
Battery:(Hitachi Maxel Rechargeable ML1220 Battery. 3Volt) [url removed, login to view]
Power on/off switch: Low profile side switch.
Led Light: Smallest possible
Connector/charge: connect/charge same connector, Low profile Molex Female and mail to PC USB
We would like to control the sensitivity of the (Touch PAD adhesive plate/capacitive touch pads) via a low profile wheel switch, or possible by the software is fine too.
Software Structuring & Firmware will be very simple on this first prototype
Example all enter keys will be save to Flash memory with time stamp
Time stamp can be synchronize via the PC real time.
RTC is not needed.
We can discuss the simple structuring of the first prototype via PM.
We would like to test how well this go with the first prototype and on are finial prototype we would like to add a LCD and upgrade the Firmware Ect.
- Schematic capture (Altium format)
- BOM Excel format
- PCB layout design files
- Final board house Gerber files
- Final assembly documentation
- And anything else required for us to manufacture of a prototype
We need a functioning working prototype to Test
We will use only escrow for payment.
A schematic of a 16 keypad layout is attached.
Please view attached PDF file.
More or less this is how I want the final product to look but with minor adjustments.
