Boardoza E22-900M22S LoRa® Breakout Board
The Boardoza E22-900M22S Breakout Board is a compact long-range wireless communication board based on the Ebyte E22-900M22S LoRa® module. Powered by the Semtech SX1262 RF transceiver, it supports both LoRa® and FSK(Frequency Shift Keying) modulation, enabling reliable low-power wireless communication over the 850–930 MHz ISM frequency range, including the widely used 868 MHz and 915 MHz bands. The onboard 32 MHz TCXO (Temperature Compensated Crystal Oscillator) provides excellent frequency stability, making it suitable for narrowband communication and outdoor deployments.
The breakout board exposes the module's SPI interface, RF control signals, and status pins through standard headers, allowing easy integration with development platforms such as STM32, ESP32, Arduino, and other 3.3V-compatible microcontrollers. With its SMA antenna connector, industrial operating temperature range, and long communication distance, this board is ideal for IoT gateways, smart agriculture, telemetry, environmental monitoring, industrial automation, and wireless sensor networks.
