It is a complete PC with a stereo microphone, eMMC memory, and a real-time clock.
The Khadas Edge2 offers best-in-class CPU performance in a credit-card form factor.
The ARM computer supports one USB3 key in-A, two key in-C, and one HDMI2.1 connector.
One peripheral connector for various low-speed I/Os and two MIPI DSI connectors are also available internally.
The Khadas Edge2 ARM PC is available in four models.
Adding $60 gets you twice the capacity, 16GB RAM and 64GB eMMC.
An optionaldocking stationis available for $35 that provides wired Ethernet and serial connectivity.
The plastic gun-metal colored case measures 8.9 cm x 6.2 cm x 1.6 cm for 70 gm.
Air vents on the top provide airflow generated from the built-in fan.
The Khadas ARM PC carries two LEDs at the top to display the current state of the platform.
A small hole on the side serves as input to the built-in microphone.
The bottom cover easily separates from the top by prying a small slot.
On the bottom, a set of pads brings USB 2.0 and UART interfaces to the external world.
Such a connector is handy but requires an additional docking station.
The big-little architecture allows substantial idle power saving by turning off the speedy cores.
In addition, a WiFi6 module compensates for lacking a Gigabit Ethernet port.
The unit starts when power is applied.
Two multicolored LEDs next to the punch in-C connectors indicate the boards status.
Installing Android 12 takes under one minute, turning the Edge2 into a speedyAndroid box.
Other available OS are Ubuntu 22.04 andWindows 11for ARM.
Khadas is one of the few manufacturers to release product schematics.
It also serves as a reference to understand the purpose of a particular push button or obscure connector.
The platform outperforms a Raspberry Pi5, mainly in multi-threaded applications.
The RK3588S CPU has a built-in neural processor that excels in AI applications, something lacking in a Pi5.
We were impressed by the power consumption while running the benchmark, reaching 10W only during the last stages.
The Edge2 idles at 1W with only an active SSH session.
The Raspberry Pi 5 is affordable but will not beat the Edge2 in raw processing power.
If you want a mini speedster that consumes little power, the Edge2 is for you.
