Grove - Wio-E5 is a compact LoRaWAN wireless module built around the Wio-E5 STM32WLE5JC module, combining an Arm Cortex-M4 ultra-low-power MCU core with an SX126x long-range radio. It supports AT-command control, LoRaWAN networking, and common regional frequency plans for fast sensor-node and IoT prototyping.The Grove connector makes it easy to add long-range wireless communication to supported development boards. The module can connect to LoRaWAN server platforms such as The Things Stack and ChirpStack, and it also exposes useful MCU interfaces for projects that need more flexible peripheral expansion.Features Wio-E5 STM32WLE5JC module with Arm Cortex-M4 MCU and SX126x long-range radio LoRaWAN support with regional plans including EU868, US915, AU915, AS923, KR920, and IN865 AT-command firmware for fast integration through UART control Grove plug-and-play connector with 3.3V / 5V supply support LoRa, (G)FSK, (G)MSK, and BPSK modulation support Up to +20 dBm output power at 3.3V and 60 uA sleep current Useful expansion interfaces such as UART, I2C, ADC, and GPIO Designed for wide-temperature deployments from -40°C to 85°C Applications Low-power LoRaWAN sensor nodes Smart agriculture and environmental monitoring Wireless meter reading and smart-city endpoints Battery-powered long-range sensor networks Grove-compatible IoT prototypes and gateways Specifications Supply Voltage 3.3V / 5V Wireless Module Wio-E5 STM32WLE5JC MCU Core Arm Cortex-M4 Radio SX126x long-range transceiver Frequency Plans EU868, US915, AU915, AS923, KR920, IN865 Working Frequency 868 MHz / 915 MHz Protocol LoRaWAN Output Power Up to +20 dBm at 3.3V Sensitivity -116.5 dBm to -136 dBm Modulation LoRa, (G)FSK, (G)MSK, BPSK Sleep Current 60 uA Interfaces UART, I2C, ADC, GPIO Dimensions 20 x 40 mm Operating Temperature -40°C to 85°C Certifications FCC, CE, TELEC Hardware OverviewThe board integrates the Wio-E5 module, Grove connector, power indicator, and labeled signal pads. It can be used as a ready-to-connect LoRaWAN module, while the linked hardware files help with schematic review and carrier-board planning.Other ContentThe factory AT firmware is programmed and protected at RDP level 1. If the factory AT firmware is erased or the RDP level is changed from level 1 to level 0, the flash memory is mass-erased and the factory AT firmware cannot be restored.Part List Grove - Wio-E5 PCBA 1 Grove Universal Cable 1 Resources Grove - Wio-E5 Wiki LoRa-E5 STM32WLE5JC Module Wiki Grove Wio-E5 v1.0 PDF Grove Wio-E5 v1.0 Schematic Grove Wio-E5 v1.0 Board File Wio-E5 Module Datasheet Wio-E5 AT Command Specification STM32WLE5JC Datasheet FAQWhich LoRaWAN regions does this module support?The official documentation lists EU868, US915, AU915, AS923, KR920, and IN865.
