Digital Phased Arrays, Made Affordable
ESPARGOS builds low-cost digital phased arrays for wireless sensing from commercial off-the-shelf wireless communications chips. ESPARGOS One is our first dual-polarized 4 × 2 antenna array for the 2.4 GHz band, built from phase-synchronized ESP32 chips. Explore wireless signals through phase-coherent WiFi CSI and raw I/Q samples.
