I'm working on my engineering thesis - Miniature viscosity and density measurement device. The main goal is to put whole measurement system on one small board and make device handheld.

Whole device in enclosure should look like electronic thermometer (maybe little bigger).

To make device small and portable and to achieve low measurement noise I need to design 4-layer PCB. This will allow me to make complete measurement system on one board, including:

- precision analogue front-end

- powerful Cortex M4 MCU

- COG LCD Display

- USB input with li-po charger

- ultra low noise power supply

I want to fit my device on 28x100mm board with standard clearance and drill size.
