- QuadRF is a 4x4 MIMO software-defined radio (SDR) tile with an integrated Raspberry Pi 5, functioning as a real-time RF camera.
- It uses four coherent antennas to visualize radio sources (like Wi-Fi devices and drones) in 2D at 30fps via a web GUI on phones or laptops.
- The kit includes everything needed out-of-the-box: antennas, Pi 5, software, and supports full-duplex transmission and beamforming.
- QuadRF is designed for scalability, allowing tiling into larger phased arrays for applications like moon bounce communication or radio telescopes.
- Priced at $499, it offers an affordable alternative to expensive SDRs (e.g., USRP models) by using custom, cost-effective hardware and open-source software.
- Production is backed by automated QA, with global shipping handled by Mouser Electronics, and community support via Discord and open-source resources.
