Grove Wio-E5 embedded with Wio-E5 STM32WLE5JC, powered by ARM Cortex M4 ultra-low-power MCU core and Long Range SX126x, is an easy-to-use wireless radio module, supporting LoRaWAN protocol on the EU868 & US915 frequency and (G)FSK, BPSK, (G)MSK, Long Range modulations.
As an upgrade of our old version - Grove - Long Range Radio - powered by RFM95 ultra-long-range Transceiver Module, Grove Wio-E5 embedded with Wio-E5 STM32WLE5JC Module is a high-performance and easy-to-use wireless radio Long Range module supporting LoRaWAN protocol.
Wio-E5 LoRaWAN STM32WLE5JC module is the major functional part integrated into Grove - Wio-E5. It is a LoRaWAN module embedded with ARM Cortex M4 ultra-low-power MCU core and Long Range SX126x, as the world-first combo of Long Range RF and MCU chip into one single tiny module, it supports (G)FSK, BPSK, (G)MSK, and Long Range modulations, and is FCC, CE certified. Grove - Wio-E5 features an extremely compact size, ultra-low power consumption, low cost, and amazing performance.

1. Factory AT Firmware
Wio-E5 series has a built-in AT command firmware, which supports LoRaWAN Class A/B/C protocol and a wide frequency plan: EU868/US915/AU915/AS923/KR920/IN865. With this AT command firmware, users can easily and quickly build their prototype or application.
The AT command firmware contains a bootloader for DFU and the AT application. The "PB13/SPI_SCK/BOOT" pin is used to control Wio-E5 to stay in the bootloader or jump to the AT application. When PB13 is HIGH, the module will jump to AT application after reset, with a default baud rate of 9600. When PB13 is LOW (press the "Boot" button on Wio-E5 Dev Board or Wio-E5 mini), the module will stay in the bootloader, and keep transmitting a "C" character every 1S at baud rate 115200.
