We previously described issues with the old original WFI shield in this journal. We do not know if the described issues are resolved in the OpenBCI modules listed here. We did not test it ourselves. The description of the listed OpenBCI modules says that the issues with the WIFI shield are resolved. Buy and test it at your own risk.
