pinouts

Postby mpaulin » Sat Apr 19, 2014 2:32 am

Hi:

Do you have a schematic? I want to know the pin connections from sensors to the MCU, so I can break off the sensors and re-attach them with leads.

The links to hardware and software manuals in this section are broken.

Thanks.

Hi there,

There is a hardware quick guide with basic pinout and description of each module available online at:
http://www.biosignalsplux.com/downloads ... anual.html

All of the boards should have labels on the back indicating which pin corresponds to what; we’ve tried to follow as much of a standard notation as we could… essentially you should find the following:

AVCC: Regulated 3.3V power dedicated to the analog sensors
AGND: 0V ground dedicated to the analog sensors
AVSS: Regulated 1.65V mid-point voltage dedicated to the analog sensors

DVCC: Regulated 3.3V power dedicated to the digital components (Bluetooth, MCU, etc.)
DGND: 0V ground dedicated to the digital components

Ax: Analog output ‘x' (on the sensor boards); Analog input ‘x' (on the MCU board)

Ox: Digital output ‘x'

Ix: Digital input 'x'

IN-: Negative electrode pole
REF: Reference (or mid-point) voltage
IN+: Positive electrode pole

There's also a small tutorial on how to put together a BITalino Freestyle into a working unit:
