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?

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.
