hi Yiping, i also just study the Variscite DART-6UL or TechNexian PICO-IMX6ULL.

Not sure if they have any local support in APAC region?  Do you have any contact point to share?

[yipingwang]

Both TechNexion and Variscite support APAC customers. For Singapore, TechNexion may provide more convenient regional support due to its Taiwan headquarters. I recommend contacting TechNexion ([email protected]) and Variscite ([email protected]) directly to discuss Singapore distribution coverage, local support resources, stocking policy, and design-win support

1. NXP i.MX93 SOM (Best Long-Term Option)

The i.MX93 supports:

• 24-bit Parallel RGB Display
• eMMC 5.1 
• Multiple SPI interfaces 
• Gigabit Ethernet with TSN

Pros

• Current generation MPU
• Long NXP longevity roadmap
• Lower power than AM335x
• Linux support active for many years

Cons

• Native SGMII not directly available like Layerscape/i.MX95
• SOM price typically exceeds US$45 once 512MB DDR + 8GB eMMC are included

Expected SOM Price

• Approximately US$45–60 depending on volume

2. NXP i.MX6ULL SOM (Best Price Match)

The i.MX6ULL provides:

• 24-bit Parallel RGB LCD interface up to WXGA
• eMMC support
• SPI ports
• 512MB DDR variants readily available

Typical SOM configurations already exist with:

• 512MB DDR3
• 8GB eMMC
• Dual Ethernet

Pros

• Closest price to AM3354
• Mature Linux BSP
• Large SOM ecosystem
• Easy migration from AM335x-style designs

Cons

• No native SGMII
• Ethernet limited to Fast Ethernet (10/100) on most modules

Expected SOM Price

• US$25–40 in production volumes
•  

For native SGMII, you'll generally move to:

• i.MX94x / i.MX95 families 
• Layerscape LS1028A/LS1043A

These usually push SOM pricing well beyond US$44.
