Linux-driven STM32MP1 module measures less than one square inch

Mar 5, 2019 — by Eric Brown — 1093 views

Kontron unveiled a 25.4 x 25.4mm “SOM-STM32MP157” module that runs Linux on ST’s new dual-core -A7 SoC plus a new baseboard equipped with 2x LAN, 2x USB, serial, DIO, and DSI.

Kontron announced a tiny computer-on-module that extends STMicroelectronics’ new STM32MP1 SoC.

The solderable, 25.4 x 25.4mm SOM-STM32MP157 is one of the smallest compute modules we’ve seen. There’s also a new baseboard for prototyping and a preloaded Yocto Project based Linux stack with communications and LCD/touch drivers. The products are aimed at industrial automation, IoT, medical, and POS/POI applications.

The low-power STM32MP1 SoC will appear on several ST developer boards due in April, as well as Arrow’s sandwich-style, 96Boards CE Extended form-factor Avenger96 board. Like the Avenger96, the SOM-STM32MP157 integrates the high-end STM32MP157 model, which like the two other STM32MP1 variants, offers dual, 650MHz Cortex-A7 cores and a 209MHz Cortex-M4 chip. The STM32MP157 SoC includes a 533MHz Vivante 3D GPU with support for OpenGL ES 2.0 and 24-bit parallel RGB and MIPI-DSI displays at up to 1280 × 800 at 60fps.

The SOM-STM32MP157 module ships with 256MB to 512MB DDR3, 2MB NOR flash, 256MB to 512MB NAND flash, and an RTC. The 3.3V module is equipped with an Ethernet controller that supports 2x 10/100Mbps ports, as well as support for 2x USB 2.0 ports and MIPI-DSI and RGB displays.

Additional I/O includes up to 8x UART, 2x CAN, 6x I2C, 6x SPI, 4x PWM, and 3x SDIO. You also get up to 2x DAC, 17x analog inputs, and 98x GPIO. Customers can choose from 0 to 70°C and -40 to 85°C tolerant models.

The new “SOM-STM32MP157 with Baseboard” carrier has a 105.5 x 67mm “4.3-inch” form factor with a 9-32V DC input and 0 to 70°C support. The baseboard integrates the SOM-STM32MP157 module with the maximum RAM and NAND capacities and adds 4GB to 8GB eMMC and a microSD slot.

The baseboard is equipped with dual Fast Ethernet, 2x USB 2.0 host, and a micro-USB OTG port. A terminal input can act as either an RS-485 or CAN interface.

Other I/O includes RS-232, 2x DIO, and 2x analog inputs. You can choose either a DSI or RGB interface with capacitive touch support, and there are 1W mono and Piezo headers for audio. A coin-cell battery is provided for the RTC.
