    ROCK 3 >  ROCK 3 Compute Module >  Radxa E23 Dual Ethernet Board

Radxa E23 Dual Ethernet Board is an application board for the ROCK3 Compute Module(CM3).

E for Ethernets.

This is the documentation for Radxa E23, written by Radxa Team with community contributions.

Radxa E23 is a Rockchip RK3566 based SBC(Single Board Computer) by Radxa. It equips a 64bits quad core processor, USB 3.0, dual ethernets (one 1G and one 2.5G ethernet), wireless connectivity at the size of 2.5x2.2 inch(56x65mm), making it perfect for IoT and network applications. Radxa E23 comes in various ram sizes from 1GB to 8GB LPDDR4, and uses uSD card for OS and storage as well as supporting eMMC module. Optionally, Radxa E23 supports PoE, additional HAT is required.

MicroSD

Audio: 3.5mm jack with MIC

Audio can be played through speaker or headphones using a standard 3.5mm jack with MIC.

Note that HD codec supports up to 24-bit/96KHz audio.

LED

One Green Flashing LED is on Radxa CM3 shows running kernel.

One RGB LED is controlled by three PWM channels. They can be controlled via sysfs. Below is their related sysfs directories.
