Ebyte UART Wireless RF Module Selection Guide
Ebyte UART (TTL) wireless RF modules integrate a high-speed MCU and high-performance RF chip, providing standard UART interface with transparent data transmission. Engineers can realize wireless communication between modules and host MCUs without mastering complex RF protocol stacks, greatly reducing development difficulty and shortening R&D cycles.
All series support functions such as fixed-point transmission, broadcast transmission, forward error correction (FEC), watchdog, deep sleep, air wake-up, parameter saving and variable packet length. They are widely used in industrial IoT, smart home, security monitoring, agricultural sensing and consumer electronics fields.
