About

The CANSAT Transmitter Module is an RF subsystem specifically engineered for applications requiring a low-cost and low-power radio link. It is fully compatible with the AX.25 protocol, utilizing Unnumbered Information (UI) packets for data transmission. The module offers flexible data rates, capable of operating at both 1200 bps and 9600 bps. Furthermore, it provides the functionality to format data packets to conform to the widely used APRS packet structure, enhancing its utility for various amateur radio and CANSAT-related communication tasks. This makes it suitable for educational projects, amateur satellite communication, and other small-scale space-related data transmission needs.
