Radxa X4 - Credit Card Size, Big Performance: Intel N100 and RP2040 Inside

Radxa X4, champion of the boards, credit card sized single board computer (SBC), with big X86 performance.

Great product, invest in thermal solution

The combination of an Intel CPU and RP2040 extensibility is a great value. And a 6W efficient machine with Intel-architecture universality. However despite the low power draw, the machine can get quite hot. There are several cooling solutions out there, sadly the default Radxa Heatsink cannot PWM-control the fan speed and just keeps spinning constantly. That does keep the temperature to good levels, but is certainly audible in silent environments.

Amazing Board

Much more powerful than a RPi 5, and they have a proper PoE shield for it.
