Hi,
thanks for the answer. I'm using an SD card shield (in particular this one https://www.sunfounder.com/sd-card-modu ... eader.html) with an Arduino Mega. It has a voltage regulator, so is possible to power both with 3.3V and 5V and the interface is SPI. I send the sensors data with your Lora module connected thanks to the multiprotocol shield but I want save the data in a SD, too.
As for the other guy, when the multiprotocol shield is connected to Arduino, the SPI pins on Arduino no longer work.
Could you help me?
Thanks

Hi jakky90,

As we say in the Multiprotocol tutorial (2.2 section):
The Multiprotocol Radio Shield includes SPI bus connection in the two sockets, but the voltage levels of the sockets are not the same. The SOCKET0 of the Multiprotocol Radio Shield uses 5V voltage levels and the SOCKET1 uses 3V3 voltage levels.

You can connect the LoRa module to SOCKET1(3V3) and the SD card to SOCKET0(5V) but you need a "5V SD card breakout" and wire to SOCKET0 SPI signals.

The socket0 pinout is:
PIN_01: VCC
PIN_04: MISO
PIN_10: GND
PIN_11: MOSI
PIN_17: CSn
PIN_18: SCLK

We have never tried it but we think that it can work.

Regards
