Experiences with RFM9x and SX127x based SPI LoRa modules

The HPDTek HPD13A is a SX1276 (and RFM95W) compatible module but then shielded.
I remember having read somewhere: that it has a 4-layer PCB while RFM95W has 2-layer PCB.

The HPD13A module is used on boards like BSFrance LoRa32u4 II, TTGO LoRa32 V2.x and TTGO T-Beam.
