Adafruit CircuitPython 8.0.0-beta.0 on 2022-08-18; Adafruit QT Py ESP32S2 with ESP32S2 are used to create a Redundant Array of mDNS http Servers. The devices could be physically together or scattered around, as long as they are on the same LAN. Once configured, no USB connection is necessary for operation.
