Why this Kit?
One Carrier, Every TX Module
The DIMM200 socket on TX Mainboard-7 accepts every Ka-Ro TX module — i.MX 93, i.MX 91, i.MX 8M Plus, RZ/G2L, STM32MP and more. Validate one application across the entire family on the same hardware.
EdgeLock Hardware Security
NXP EdgeLock secure enclave provides hardware-rooted secure boot, cryptography and tamper detection — out of the box.
Headless & Display Ready
Boots straight to a serial console out of the box. Add the optional 10.1″ touch display via the Mainboard-7 LVDS connector when you need an HMI.
Made in Germany
TX Mainboard-7 and TX-family modules are designed and manufactured by Ka-Ro Electronics. 12-month warranty and 10+ year availability commitment.
Software & Support
Yocto-Linux BSP
Reference image based on Yocto kirkstone / scarthgap. Boots straight to a Linux console out of the box.
Mainline U-Boot + Linux Kernel
Long-term-supported sources, including Ka-Ro device-tree overlays and module-specific patches.
Schematics & Design Package
Full carrier-board schematics, gerbers and BOM available on request to support your own carrier design.
