Lora E5-HF module vs STM32WLE5JC


Can somebody explain what are the benefits of using the Lora E5 HF over the STM32WLE5JC module itself. The STM32 part has a Sub-GHz radio system peripheral in the module already so doesn’t really need an additional SX126X…

I can see that if you use it “as is”, there is the benefit of not having to write the code for the module but there is also instructions how to erase the firmware it’s shipped with an reprogram with STM32 software.

Many thanks.

“It contains ST system-level package chip STM32WLE5JC, and this STM32WL module is the first SoC integrated with the combo of LoRa RF and MCU chip. This module is also embedded with ARM Cortex M4 ultra-low-power MCU and LoRa SX126X and therefore supports (G)FSK mode and LoRa.”

I don’t quite understand your question
Lora-E5 is “STM32WL + crystals, RF-matching networks and other passive elements”.
