Buttons and Status LED

Status LED

This product has an LED status indicator on the backside, as the figure below shows. The LED turns GREEN when the device is turned on and flashes YELLOW when the CPU is working.


Figure 1014: Status LED


There are three (3) buttons on the backside of the case: Volume +, Volume -, and boot mode selection, as the figure below shows.


Figure 1015: Buttons

The AIO-CM4-101 industrial Pi PC boots from the internal eMMC by default. If you want it to boot from the USB TYPE-C connector, please press the Boot Mode button before power ON, and release it 3 seconds after power ON. If you use CS12800RA4101A_C121, the Boot Mode button had been changed to VOL+, you should press VOL+ to enter USB download mode.


There are many connectivity options available on the AIO-CM4-101 industrial Pi PC. It has 2 x USB 2.0 Host, 1 x USB TYPE-C, 1 x Channel Giga LAN (RJ45) Ethernet connector supporting up to 1 Gbps, and RS232+RS485+Relay connector.


There are 2 x Type A USB HOST connectors and 1 x USB TYPE-C Connector onboard, as shown on the figures below.


Figure 1016: USB HOST and USB TYPE-C Connectors


  • External USB peripherals like a USB disk or USB mouse or keyboard can connect to the USB HOST.

  • You can download software to the Raspberry Pi CM4 eMMC using the USB TYPE-C.

  • When you connect the USB TYPE-C to a device, it will disable the USB HOST.

LAN Connectors

LAN (RJ45) connector provides Ethernet connectivity over standardized Ethernet cables as shown the figure below. The integrated Ethernet interface supports up to 1 Gbps data throughput. These Giga LAN signals come from the CM4 module directly.


Figure 1017: RJ45 LAN Connectors


Use CAT5 or better cables to achieve full data throughput over maximum distance defined by the 1000BASE-T standard (100m).

TF Card and SIM Card Slots

The AIO-CM4-101 industrial Pi PC features 1 x TF Card (micro SD) slot and 1 x SIM Card slot. You can use the SIM card slot when you mount the 4G/LTE module.
