Microcontroller to be used in the project

A project log for Publys: An open source biosensing board

Publys is an open source platform for the study and processing of bioelectric signals.

The Publys platform in its version V1.0 will use an Atmega328P as a microcontroller, I hope for future versions to replace it with another one of better features and greater security.

The PCB shown in the image corresponds to a custom design made for a company, this has a better with respect to the Lilypad Arduino board. I will use this board because it will allow me to do quick tests as I elaborate each one of the sensors of the project. This will be a way to validate the prototype quickly and without the need to generate high costs in the prototyping phase.
This is a 2-layer PCB, which allows access to all ports of the microcontroller, also can be powered by a 3.7V Lithium battery, this is one of the advantages and allows the device to be portable.

In future updates I hope to give new advances in device hardware development.
At the moment I am working on the design of the following sensors, as well as on the design of the feeding stage of the project.
