Itsy Bitsy M0 with Dragino Shield

Projects Networking, Protocols, and Devices

Has anyone been able to connect the Adafruit Itsy Bitsy M0 Express with the Dragino Shield?

I used the following connections:

Dragino Shield Itsy Bitsy M0 Express

2 7
6 13
7 12
9 9
10 10
11 MOSI
12 MISO
13 SCK
3.3V 3V
GND GND

I also updated the LMIC pin mapping:

const lmic_pinmap lmic_pins = {
.nss = 10,
.rxtx = LMIC_UNUSED_PIN,
.rst = 9,
.dio = {7, 13, 12},
};

I am using the example from GitHub - matthijskooijman/arduino-lmic: This library is deprecated, see the README for alternatives.

The code compiled successfully and I could also upload it to the MCU. However, I couldn't access the Serial Port after uploading the code and nothing seemed to happen...

Does anyone have an insight into this problem?

Thanks,
Jasch

I'm missing the link to the used hardware. Dragino is selling several shields, which one are you using?

Oh sorry. Here is the link:

You must connect IOREF of the Lora Shield to your IO voltage, so 3.3V for your Itsy. The shield uses that as the reference voltage for the level converters.
