I have been working with [a module](https://www.thethingsnetwork.org/forum/t/the-workbench/8970/15) that’s equal to adafruits feather 32u4.

LMIC\_reset();

// Set up the channels used by the Things Network, which corresponds  
// to the defaults of most gateways. Without this, only three base  
// channels from the LoRaWAN specification are used, which certainly  
// works, so it is good for debugging, but can overload those  
// frequencies, so be sure to configure the full frequency range of  
// your network here (unless your network autoconfigures them).  
// Setting up channels should happen after LMIC\_setSession, as that  
// configures the minimal channel set.

```
#if defined(CFG_eu868)
LMIC_setupChannel(0, 868100000, DR_RANGE_MAP(DR_SF12, DR_SF7), BAND_CENTI); // g-band
LMIC_setupChannel(1, 868300000, DR_RANGE_MAP(DR_SF12, DR_SF7B), BAND_CENTI); // g-band
LMIC_setupChannel(2, 868500000, DR_RANGE_MAP(DR_SF12, DR_SF7), BAND_CENTI); // g-band
LMIC_setupChannel(3, 867100000, DR_RANGE_MAP(DR_SF12, DR_SF7), BAND_CENTI); // g-band
LMIC_setupChannel(4, 867300000, DR_RANGE_MAP(DR_SF12, DR_SF7), BAND_CENTI); // g-band
LMIC_setupChannel(5, 867500000, DR_RANGE_MAP(DR_SF12, DR_SF7), BAND_CENTI); // g-band
LMIC_setupChannel(6, 867700000, DR_RANGE_MAP(DR_SF12, DR_SF7), BAND_CENTI); // g-band
LMIC_setupChannel(7, 867900000, DR_RANGE_MAP(DR_SF12, DR_SF7), BAND_CENTI); // g-band
LMIC_setupChannel(8, 868800000, DR_RANGE_MAP(DR_FSK, DR_FSK), BAND_MILLI); // g2-band
#endif
