got it today and after soldering the usual connection DIO1 --> pinX it worked with the LMIC library and the prviously used code for the adafruit feather M0.
the board is 2.54mm wider than the original feather, but it could be a cheap substitute.
attention: the documentation notes the pin wron. look in LoRa.h
and you don’t need to install suggested libryry, because that’s forseen for node to node connection
// Adapted for DIYmall feather clone DIYLoRa32u4 Doc: ss = 19 , Reset = 9 , DIO0 = 26 (from LoRa.h)
// from Exemple Sender: ss = 8 , Rst = 4 , DIO0 = 7
const lmic_pinmap lmic_pins = {
.nss = 8, // chip select on clone (rf95module) see LoRa.h
.rxtx = LMIC_UNUSED_PIN, //
.rst = 4, // reset pin (M0=4)
.dio = {7, // DIO0 is hardwired to 7
5, // DIO1 is jumpered to 5
LMIC_UNUSED_PIN}, // DIO1 is jumpered to unused
};```
have fun :slight_smile:
