AEC-Q100 qualified module includes Allwinner T507-H processor for automotive applications

We first wrote about Allwinner T507 when we covered a module and development kit from Forlinx, but now MYiR Tech has designed its own AEC-Q100 qualified System-on-Module (MYC-YT507H) and MYD- YT507H based on Allwinner T507-H processor.

MYC-YT507H block diagram

It is unclear if there are any differences between Allwinner T507 and T507-H processors with respect to the specifications, so I asked, and was told that the T507-H also supports HDMI, and not only LVDS and composite like the Allwinner T507.

The company provides Ubuntu 18.04.5 with Linux 4.9 desktop environment and XFCE, or Qt5-based MYIR MEasy HMI V2.0 system with local (display) and remote (web-based) human-machine interface to control all I/O. including RS232, RS485, Ethernet, CAN Bus, etc.


Open source drivers are offered with a GNU GCC binary toolchain, but only to customers. The company doesn’t seem to pay much attention to detail, as I was told about a new “AllWinner T507-H processor based SOM featuring a dual-core industrial ARM Cortex-A72 processor” and the bad product link (it’s a habit of them) in the email they sent me, so first I thought “Allwinner finally got a Cortex-A7x processor”, but that was a false alarm.

MYD-YT507H development board

MYiR Tech does at least one thing better than most industrial/embedded module vendors and that is they make their prices public and the hardware can be purchased online. The qualified MYC-YT507H AEC-Q100 CPU module retails for $34.90 (1GB RAM) or $39.80 (2GB RAM), while the development board costs $119. More details and purchase links can be found at the product sheet.
