Specification Brand : Reland Sun BulletPoint : SX1278 LORA module 433M serial port/UART interface RA-01 BulletPoint1 : With positive and negative 15KV ESD protection, the chip has a limited slew rate driver to minimize EMI and reduce signal reflections caused by improper terminal matching cables, thereby enabling error-free signal transmission rates up to 500Kbps. BulletPoint2 : The input impedance of the receiver with a 1/4 unit load supports multi-machine communication, allowing connection to a bus of up to 128 devices. BulletPoint3 : Using 10Ω current protection resistors, patch design to improve 485 signal integrity. BulletPoint4 : With terminals and welding lead holes, convenient debugging and final fixed wiring, welding leads can improve signal reliability. BulletPoint5 : Welding holes with 2.54 pitch holes for easy secondary development. With M3 screw holes that are quite commonly used at present, easy and reliable installation.
