Modular Pressure Sensor Matrix PCBA - Part 1

**GENERIC BIDS WILL NOT BE CONSIDERED**

This is Part 1 in a large project, the successful Freelancer will be asked to join on multiple contracts if performance on Part 1 is to a good standard.

This project is for the design of a MODULAR large pressure sensor matrix PCB and requires the freelancer to develop a working PCBA, test it and deliver to our office. The pressure matrix is arranged in a grid formation, where one layer has vertical lines and the bottom layer has horizontal lines. By scrolling through each line very quickly we can determine the exact pressure positions on the sensor mat. We have used multiplexers and switches in the past to achieve this function and it worked really well so we suggest the freelancer to use a similar method. Voltage dividers also help give the matrix a wide sensing range..

We have our own sensor mat prepared so the freelancer does not need to make the mat but should perform testing with off the shelf FSR to ensure the PCB works as desired.

The PCB should also include circuitry for 6 DC vibration motor drivers which operate at 3V. The microcontroller used should have very fast processing speed to allow for quick scanning of the 1800+ sensor points. Arduino or similar programming language is preferred so we can make edits in future.

Design Requirements:

-Pressure sensor matrix interface for reading approximately 1800 sensor points (44 horizontal x 48 vertical)

-A module for playing simple sounds (buzzer or similar)

-MODULAR pressure sensor input so we can use the same PCB with different number of rows and columns of sensor lines.

-Analog reading of pressure sensor should be used, use of a voltage divider or similar circuit is recommended

-Very fast based processor, should be able to connect the PCB to a raspberry Pi to interface.

-6X vibration motor driver circuit to control 6 DC coin type motors operating at 3V

-Lipo 3.7V or 7.4V battery power, also power through USB-C when connected

-Can also be operated while plugged into the wall supply

-Fast recharging rate via micro-usb or USB-C

-BLE (Bluetooth Low Energy) for communicating sensor values to a PC or phone

-USB-C to USB or data interface to plug PCB directly to a PC for reading the values (when BLE is not used)

-Should include power button or ON/OFF switch to turn the PCB ON/OFF

-RGB Led for status indication, i.e. Blue LED means ON, Green LED means charging battery, Red LED means low battery, Purple LED means ON and Connected (BLE).

-Green Led to indicate charging

The freelancer is not expected to do much coding, only to test the circuit elements and features. The code is also to mainly ensure the pressure sensor matrix and power circuits are working correctly.

Project Deliverables:

1) PCB Eagle Schematic Files, BRD files, Gerber Files, BOM, X-Y pick and place, Code

2) Video of working PCB with testing

3) PCBA delivered to our office
