J.Fi Launched: Wireless Link for Drones and Robots

J.MARPLE has launched J.Fi, a wireless communication module for networks of many devices, such as drone swarms and robot fleets. It runs on the 2.4GHz WiFi band.

J.Fi supports 1:1, 1:N and N:N links. Time slot-based response delay management prevents collisions, even when many devices share the network. The range is up to 1 km, depending on the environment, and the data rate can be set from 250Kbps to 11Mbps.

Setup takes two buttons and a web browser. J.Fi is built on the KC-certified ESP32-WROOM-32UE, with 4MB flash, two UART ports and USB, in a 45 × 35 × 10 mm package.
