Power supply

Radxa E23 is powered by Type-C port with 5V input, you can power it from 5V USB adapter or from PC/Laptop USB port.

eMMC

Radxa E23 is equipped with different capacities of eMMC (8/16/32/64/128GB). See Radxa CM3 Models and SKU.

DDR

Radxa E23 is equipped with different capacities of DDR (1//2/4/8GB). See Radxa CM3 Models and SKU.

Wireless module

With Wireless variant SoM, Radxa E23 have WiFi 2.4G&5G and Bluetooth 5.0 capability. To gain a stronger signal, you need an antenna attached to the antenna socket on board. The u.FL connector type is IPEX Gen 1.

Ethernet

Radxa E23 has one 1GbE LAN port and one 2.5GbE LAN port.

1GbE LAN port LED status and speed table.

LED speed

PIN#2 5V

TF/MicroSD

The TF card can be used as a system storage or an external storage. When it's used as a system storage, you had better choose the ones with storage space larger than 8GB. When it's used as an external storage, you can choose the ones with storage space up to 128GB. When the TF card is inserted into the TF card slot , the device will be automatically recognized by the system.

The TF card interface pin specification shows below.

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 for kernel status.

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

RGB LED --- sysfs
Red --- /sys/devices/platform/fdd70000.pwm/pwm/pwmchip*/
Green --- /sys/devices/platform/fdd70030.pwm/pwm/pwmchip*/
Blue --- /sys/devices/platform/fe6f0030.pwm/pwm/pwmchip*/

Key

There are two keys on board. One is power key and the other one is recovery key.

Key Function
Power key Power on/off Radxa E23
Recovery key Boot Radxa E23 to loader mode:
* Press recovery key and hold it
* Plug in Type-C adapter
* Wait for 5 seconds
* Release recovery key

General purpose input-output (GPIO) connector

Radxa E23 has one 40-pin expansion header.
