The Wio-E5 is an ultra-compact (12mm × 12mm), low-power LoRaWAN module powered by the STMicroelectronics STM32WLE5JC System-on-Chip, which embeds an ARM Cortex-M4 microcontroller and a Semtech SX126X sub-GHz radio onto a single die. Fully compliant with BTRC AS923 regulations, it delivers up to 22dBm transmit power and -136.5dBm sensitivity with a sleep current of just 2.1µA, making it the premier wireless engine for OEM water meters, agricultural sensors, and gas detectors developed by electronics engineers in Bangladesh.
