devices.
EDA Technology Co.,LTD– Electronics Development Accelerator
Datasheet of CM4 Nano V1.0
4.3 RTC
The CM4 Nano is integrated with RTC. For the version sold in China, we will install the CR1220 button
cell (RTC backup power supply) by default when shipping. In this way, the system can be guaranteed to
have an uninterrupted and reliable clock, which is not affected by factors such as equipment power
down.
RTC clock chip is mounted on i2c-0 bus, and the device address is 0x51.
4.4 Buzzer
CM4 Nano has a buzzer, which is controlled by GPIO6, enabled at high level and disabled at low level.
4.5 HDMI FPC
On the back of the development board, J13 uses CM4 HDMI1 signal, in the form of FPC, with USB 2.0
touch screen signal and PWM brightness level signal reserved on it, which can be connected to HDMI
touch screen.

7 FAQ
1. Why do some functions fail after installing CM4 Industrial Edition in the official system?
We recommend that customers install the system image provided by us. Otherwise, please download
our BSP to make some external interfaces work.
2.Can CM4 Nano be started in the micro SD card?
No, the micro SD card is only used for data storage. The operating system should be installed in eMMC.
3. Is there any signal occupied on the 40PIN on the CM4 Nano?
The buzzer has occupied GPIO6. If it is not needed, the resistor R39 can be removed and the GPIO6
can be disconnected from the buzzer circuit. The SD card occupies GPIO22,23,24,25,26,27. If you don't
use it, please don't insert the SD card.
4.How to install a mirror?
You can refer to the instructions by reading the software manual.
5.How to solve the error "config failed, hub doesn't have any ports! (err -19) " when opening CM4
Nano?
EDA Technology Co.,LTD– Electronics Development Accelerator
Datasheet of CM4 Nano V1.0
Delete "otg_mode=1"，[cm4] in config.txt and add "dtoverlay=dwc2,dr_mode=host"at the same time.
