Chinese developers have a new version of OpenBCI which integrates the WIFI shield in the Daisy board of OpenBCI:

Jenelson who tested Chinese OpenBCI modules in the www.openbci.com forum had issues with the4 connector between Cyton board and WIFI shield. This new OpenBCI development which can be found on Aliexpress has one connector less, which according to the developer reduces issues. This is also interesting, if we want to try to develop our own OpenBCI modules with PCBway:

To have manufactured our own physiological multi-sensor device (ironbci, openbci, phyisiological sensors & PCB) by PCBWay?

We suppose what the Chinese sell us are only demo boards. None of these developments seem to be a success up to the present day so that they would be better than modules from www.openbci.com
