Ultra-compact 45x43mm CPU module features TI Sitara AM6231, AM6252, or AM6254 Arm SoC

MYiR Tech has just announced the tiny, yet full-featured MYC-YM62X CPU module powered by Texas Instruments Sitara AM6231, AM6252, or AM6254 Cortex-A53/M4 processor for HMI and IoT applications as well as the corresponding MYD-YM62X development board used for evaluation.

The new MYiR module joins other Texas Instruments AM62x system-on-modules such as Toradex Verdin AM62, Forlinx FET625x-C, Variscite VAR-SOM-AM62, and others, but at just 45x43mm, it is the smallest AM62x CPU module we’ve seen so far yet the company says it still provides access to all features from the processor thanks to its 222 castellated holes.

The company provides Linux 5.10.168 for the module with all drivers and source code, as well as Yocto Linux images with or without GUI, and two demo applications, namely a charging pile program with Modbus communication, IEC104 platform communication protocol and a charging demonstration interface, and an “Engineering Machinery Scenarios” demo using four cameras and displaying them in mosaic form on the display. Both demos leverage the company’s MeasyHMI V2.0 graphical framework based on Qt 5. As a side note, the TI AM625 SoC is also found in the BeaglePlay SBC so software support might be indirectly available there as well.

29usd for the dual-core model is a really good price point. The support and documentation is available worth 15usd more than some random AliExpress module of a Chinese soc.
I wonder why they don’t try to mainline the kernel, to compete with nxp..
