MYD-YA157C Development Board MYC-YA157C CPU Module as Controller Board STMicroelectronics STM32MP1 MPU based on 650MHz Dual Arm Cortex-A7 and 209MHz Cortex-M4 Cores 512MB DDR3, 4GB eMMC Flash, On-board Gigabit Ethernet PHY, Power Management IC (PMIC) RS232, RS485, 1 x USB Type-C DRP, 1 x USB2.0 HOST, Gigabit Ethernet, CAN, WiFi/Bluetooth, Micro SD Card Slot Supports RGB888 based LCD/HDMI and MIPI-DSI Display Supports Running Linux OS Figure 1-1 MYD-YA157C Development Board 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), a dedicated Power-Management IC STPMIC1 also from STMicroelectronics, 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 development board is delivered with one Quick Start Guide, one Type-C cable, one USB to TTL serial cable and one WiFi/Bluetooth antenna to provide user a complete platform for evaluating and prototyping based on STM32MP1 series microprocessors. MYIR also offers MY-CAM002U Camera Module and MY- TFT070CV2 LCD Module as options for the board. 1 / 11 The MYD-YA157C is running Linux OS. MYIR provides abundant software resources for Yocto 3.1 based MYIR MEasy-HMI system (available later), Yocto 3.1 based ST Weston system, Ubuntu 18.04 system and MYIR MEasy- IOT system including kernel and driver source code, STM32CubeProgrammer and STM32CubeMX tools to enable users to start their development rapidly and easily.
