The Microhard P400 is a miniature, high-performance wireless modem designed for long-range data telemetry and serial communications in applications like unmanned aerial vehicles (UAVs), robotics, and industrial sensing. It operates in the 400 MHz band, utilizing frequency hopping spread spectrum (FHSS) technology for reliable asynchronous data transfer between devices with serial interfaces. The P400 supports point-to-point and point-to-multipoint configurations and offers features such as error correction, CRC (Cyclic Redundancy Check), and AES encryption for secure communications.
