Features 1.Full GPIOs led out from the Lora-E5 STM32WLE5JC 2.Global LoRaWAN and LoRa frequency plan supported 3.Long-distance transmission range to 10km (ideal value in open area) 4.Mini and compact size, suitable for rapid testing and building small size prototype 5.Convenient RESET and BOOT buttons on board Attention 1. Factory AT Firmware is programmed with RDP(Read Protection) Level 1, developers need to remove RDP first with STM32Cube Programmer. Note that regression RDP to level 0 will cause a flash memory mass to erase and the Factory AT Firmware can't be restored again. 2. The inchPB13/SPI_SCK/BOOTinch pin on the LoRa-E5 module is just a normal GPIO, not the inchBOOT0inch pin of the MCU. This inchPB13/SPI_SCK/BOOTinch pin is used in the bootloader of the Factory AT firmware, to decide to jump to APP or stay in bootloader(for DFU). The real inchBOOT0inch pin doesn't pinout to the module, so developers need to be careful when developing low-power applications.
