On our website you can find a table highlighting the main differences between the BITalino and biosignalsplux systems, together with a mapping of the stage of development / research for which each of the platforms has been thought for:http://bitalino.com/index.php/buy/product-finder
Essentially with biosignalsplux sensors you get higher definition, lower noise characteristics due to improved shielding, as well as smaller & more robust form factor given that the cables are directly soldered on to the sensor and encased (unlike in BITalino).
On the devices themselves, biosignalsplux hubs have higher resolution, higher number of analog input channels, possibility to have internal memory (8Gb), possibility to do data acquisition via USB (in addition to the Bluetooth wireless connectivity) and a RTC providing accurate timestamps.
If you're interested in learning more about those systems and have an online demo, please use the contact form available on the biosignalsplux website and our colleagues will be more than happy to provide you with further information:http://biosignalsplux.com/index.php/en/buy-online/demo-request
