Wio-E5 mini is a compacted-sized dev board suitable for the rapid testing and building of small-size LoRa device and application prototyping. Wio-E5 mini is embedded with and leads out full GPIOs of Wio-E5 STM32WLE5JC. It has rich interfaces including UART, ADC, SPI, IIC,etc. Supporting LoRaWAN protocol and global frequency, Wio-E5 mini is able to achieve a transmission range of up to 10 km in open area and ultra-low power consumption.
