DH Electronics introduced their Solder-on module (SOM) which can be soldered onto a carrier board. Direct soldering of the DHCOR increases operational reliability in harsh environments and saves board-to-board connectors.

With a small footprint of 29 mm² x 29 mm², the DHCOR STM32MP15x module comes with processors of the STM32MP1 family. These hybrid multi-processors combine the Cortex-M4 processor 200 MHz with one or two Cortex-A7 cores 650 MHz, and optionally a special hardware crypto unit and/or a Vivante 3D GPU with HD resolution of 533 MHz. Also, up to 1 GiB DDR3 memory, Power Management IC (PMIC), and 2 MiB SPI boot flash can be accommodated on the module.

All this gives the STM32 community a solution that improves their embedded micro-controller projects software-compatible with scalable, Linux- and Ethernet-capable hardware. If required, an optional 3D-GPU and/or a hardware crypto unit can be added. Everything is expandable and comes pre-integrated with suitable Linux BSPs.

The analog peripherals include 2x 16 bit ADC, 2x 12 bit DAC, digital filter for Sigma Delta modulator with 8 channels/6 filters, as well as a temperature sensor and an internal voltage reference source. Up to 29 timer, counter or encoder inputs, three watchdogs and 176 I/O ports are also provided. The numerous communication interfaces enable connection to a range of interfaces, including TTCAN, CAN FD, and LIN.
