This StickC Plus development board is powered by the original TI CC1101 433MHz RF transceiver, featuring a metal shielding cover for enhanced stability. It is specifically designed to expand StickC Plus wireless functions, making it ideal for IoT development, wireless signal research, remote control projects, and educational experiments. The board supports StickC Plus devices flashed with Bruce firmware, unlocking advanced RF capabilities and long-range communication. With +10dBm output power, it achieves up to 1000 meters transmission range in open areas, providing excellent penetration and diffraction performance. The metal shield minimizes external electromagnetic interference, reduces harmonic emissions, and ensures reliable operation. Comes with antenna, Grove cable, and mounting screws for a hassle-free plug-and-play setup. Note: Stick Cplus was not included.
