1.6 SMARC Interface Signals

SMARC interface signals supported by this product are listed below.

- Input/Output indicates the direction from the carrier board side.

- The signal name “Signal name”indicates that a signal is not yet used.

- “P.U” and “P.D” indicate pull-up or pull-down within SoM.

- “x” in voltage indicates it conforms to the standard of each interface.

- “SW” in voltage indicates it is connected to a Switch (contact).

- VDD_IO can be set to 1.8 V (standard) or 3.3 V. For details, see “1.9.1 VDD_IO Settings”.

For definitions of each signal in the SMARC standard, see the SMARC standard specification.

αSMARC-EVB1 Hardware Manual

1.8 Installing SMARC SoM

Install a SMARC module by plugging it into a card-edge connector on the carrier board.

The card edge connector is fragile, so handle it with adequate care.

Also, be careful not to allow dust or foreign objects to get caught in the contact area of the card-edge.

[Installation Method]

1. Insert the SMARC module diagonally (at an angle of about 30°) into the card-edge connector of the carrier board.

2. With the SMARC module inserted into the card-edge connector, push it down so that it is parallel to the carrier board.

3. Secure the SMARC module with screws.

αSMARC-EVB1 Hardware Manual

1.9 Settings

Check that jumper settings are correct before turning on the power.

There are VDD_IO(JP1) and VDD_SDIO(JP2) settings. Normally, there is no problem with keeping the factory settings.

1.9.1 VDD_IO Settings

The I/O voltage of the SMARC interface is basically defined as 1.8 V,

but some αSMARC SoM products support an I/O voltage of 3.3V. To support these products, the I/O voltage of the SMARC interface

can be switched to 3.3 V.

Note that the 3.3V setting is not normal with the SMARC standard.

JP1

Remarks

1.8 V(SMARC standard)

Factory settings

3.3 V

Make sure to match the voltage setting with the SoM setting. Damage can result from not doing this.

Also, set JP1 to 1.8 V or 3.3 V and do not leave it open.

1.9.2 VDD_SDIO Settings

It is possible to select 3.3 V or 1.8 V for the power supply of the SD card.

Currently, there is basically no problem with the 3.3 V setting.

(The UHS-I 1.8 V signal is supported by the interface function on the SoM side.)

JP2

Remarks

3.3 V(SMARC standard)

Factory settings

1.8 V

Be sure to set JP2 and do not leave it open.

1.10 Startup Check

αSMARC-EVB1 is preloaded with a Linux image when shipped.

The following is a description of how to do a startup check of αSMARC-EVB1.

SMARC SoM: αSMARC-RZ/G2E

1. Connect a PC and power supply

Attach SMARC SoM to αSMARC-EVB1 and connect the PC and AC adapter (power supply) as follows.

2. Check the settings

Before turning on the power, check that the switches of αSMARC-RZ/G2E and αSMARC-EVB1 are set as follows.
