Lora and Espruino

Also, why would someone choose the Espruino WiFi when they are connecting via LoRa? "If you're using this breakout board then you can place it in breadboard alongside an Espruino Pico or WiFi, making sure it connects as follows..."

LoRa and WiFi are totally different. With LoRa you will achieve very low power consumption. With WiFi you will benefit from relatively high bandwidth. As always, it depends on what you want to do :-)
