Fundamentally, it's possible to stack all D1 add-on boards like the ingredients of a burger. However, it's not always helpful if the sensor, display or other components are covered by the next burger layer. For example, temperature data can be falsified or a button can no longer be pressed. This board allows a D1 with two add-on boards...

Description This board offers a 10/100 Mbit Ethernet connection and a slot for an SD card. It is controlled via the SPI port and its contacts are daisy-chained, allowing other additional boards to be fitted onto it. Unfortunately, only one can be active at a time: either the SD card or the W5100 network chip. The board/software ...
