WiFi Dongle

The difference is that the telemetry requires a pair of radios: one
connected to the vehicle and another connected to an external USB
device, such as an computer or a tablet.
Using the WiFi Dongle, Erle-Brain creates a wireless network com-
patible with your existing wifi technology.
Wifi Dongle can be high or low gain, which determines the signal
range.
Buzzer
A buzzer or beeper is an audio piezoe-
lectric signaling device. Erle-Brain uses
the buzzer to signal different events.
