WiFi Extension

The WiFi Extensions make it easy to use your FPGA as an IoT controller. You have to take a cheap ESP-01 and plug it in the connector. Then you can use the FPGA as a programmer and USB interface for the ESP8266 together with the onboard buttons. And when you only have one CRUVI connector left, you can just plug a second extension like the SCD40 CRUVI module on top of the extension.
