ESP8266+Lora RFM95 (SPI)

Thanks! Actually you might find software SPI easier. Just do:

var spi = new SPI();
spi.setup({ sck:D14, miso:D12, mosi:D13 }); // or whatever pins
...connect({spi:spi...

And then you can use any pins.

To do a quick check, you could also try shorting MISO to MOSI (without the module attached) and running spi.send("Hello") - Hello should get returned.
