Has anyone seen the modules on SAMR34J18 MCU (combine SAML21 and SX1276 in one chip) ?
I spoke with Microchip a couple of weeks ago about their SAMR chips and modules. They are due out as engineering samples end of June or start of July with general availability later in the year.
I already test this modules one month ago and it works fine. Microchip give own close LORAWAN stack but easy to use Semtech stack. I think may be anybody already prepare smallest modules (less than CMWX1ZZABZ or WM-SG-SM-42).
I would suggest using the Microchip ARM stack … it is much better than the RN2xx3 PIC stack and the Semtech/Stackforce stack (spec 1.0.2 & 1.0.3 with classes A/B/C and many regions, tested daily on TUV certification system).
There are small modules in prototyping (10-11mm) but it is for them to announce on their time :))
Microchip stack looks good but i can’t find source codes.
