LoRa SIP Research

After speaking to Microchip representatives as well at colleagues at The Things Industries, we've decided to replace current module based LoRa hardware and software stacks with the ATSAMR34J18 which includes a MCU with USB.

It will be a welcome challenge to integrate tooling for the 64-pin 6mm square BGA with dense 0,65mm pitch between balls.

We have been loaned a SAMR34 Xplained Pro Evaluation Kit by Microchip Technology. Our particular model includes a Atmel WLR089 module, which bundles the ATSAMR34 MCU with a subgigaherz Semtech SX1276 transceiver and several other components. We received this developer kit that is not available on the market yet.
