Overview
The TXMP is a SO-DIMM Computer-on-Module from Ka-Ro electronics, part of the TX Family. Built around the STM32MP157C dual Cortex-A7 processor with an additional Cortex-M4 co-processor at 209 MHz, the TXMP delivers robust industrial performance with 512MB DDR3L RAM and 4GB eMMC storage in the standard DIMM200 form factor (67.6mm x 26mm x 4mm). With a Vivante 3D GPU, 24-bit RGB and MIPI-DSI display interfaces, secure boot, and CAN-FD support, it is ideal for industrial HMI and control applications.
