MYIR MYC-LMX91 System-On-Module (SOM)

MYIR MYC-LMX91 System-On-Module (SOM) is a compact and robust SOM measuring 37mmx 39mm, fully compatible with MYIR’s MYC-LMX9X (i.MX93) module. The MYIR MYC-LMX91 is powered by NXP's i.MX91 single-core Arm® Cortex®-A55 processor running at 1.4GHz. The module integrates 1GB LPDDR4 memory, 8GB eMMC storage, and a 32KB EEPROM. It also features the PCA9451AHNY power management IC (PMIC). The MYC-LMX91 offers extensive peripheral and I/O connectivity through a 218-pin LGA expansion interface, including two Gigabit Ethernet, two USB, eight UART, eight SPI, two CAN-FD, and supports a 24-bit parallel RGB display. The SOM comes pre-installed with the Linux 6.6.36 operating system, backed by comprehensive documentation and software support. Designed for reliability and scalability, the MYC-LMX91 offers a cost-effective and high-performance embedded solution for next-gen smart devices, ideal for applications such as EV charging stations, human-to-machine interfaces (HMIs), smart home/building automation, and industrial gateways.
