The MYD-YA157C development board consists of a compact CPU Module MYC-YA157C and a base board to provide a complete evaluation platform for ST STM32MP1 Processors which features dual-core Arm Cortex-A7 operating at up to 650 MHz and an embedded Cortex-M4 core operating at up to 209 MHz. Typical applications are industrial control, consumer electronics, smart home, medical and more other energy-efficient applications which require rich performance and low power.

The MYD-YA157C has a base board which installed MYC-YA157C CPU Module through 1.0mm pitch 164-pin stamp-hole (Castellated-Hole) interface. The MYC-YA157C CPU Module is a highly-integrated SoM which combines the STM32MP157 processor (STM32MP157AAC3), 512MB DDR3, 4GB eMMC as well as an integrated GigE PHY chip. The base board has brought out rich peripherals through connectors and headers such as RS232, RS485, USB Type-C DRP, USB2.0 HOST, Gigabit Ethernet, WiFi/Bluetooth, CAN, Micro SD Card Slot, JTAG, RGB888 based LCD/HDMI, MIPI-DSI, etc.

The MYD-YA157C is running Linux 5.4.31. MYIR provides abundant software resources for Yocto 3.1 based MYIR MEasy-HMI system, Yocto 3.1 based ST Weston system, Yocto 3.1 based MYIR MEasy-IOT system and Ubuntu 18.04 system including kernel and driver source code, STM32CubeProgrammer and STM32CubeMX tools to enable users to start their development rapidly and easily.
