Shenzhen, China. MYIR released its MYC-YT113i CPU Module with an integrated Allwinner’s T113-i dual-core ARM Cortex-A7 processor utilizing 128MB on-chip DDR3 memory and external DDR3 memory options of 512MB/1GB. The solution fits snuggly in a miniscule 39mm by 37mm design carrying IO signals through 140-pin stamp-hole interface and 50-pin LGA pads.

MYIR’s MYC-YT113i is Linux ready making it suitable for applications within HMI, industrial automation, display, and control terminal usage. The platform allows designers to enjoy development through prototyping to evaluating purpose.

Interfaces and peripherals include serial ports, one Gigabit Ethernet, two USB 2.0 HOST and one USB 2.0 OTG, one Micro SD card slot, one M.2 Socket for USB based 4G/5G LTE Module with two SIM card holders, one USB2.0 based WiFi module, one GPIO/I2C/UART/SPI/CAN extension header, Audio input/output, and LVDS display interface.
