Industrial grade -45+85C STMP1-SOM is almost completely routed and pin to pin compatible with A13-SOM

A13-SOM-256 and A13-SOM-512 are low cost Linux running System on Modules which are very popular but lack industrial grade operating temperature.

STM32MP1XXX series of SOC from ST is the first mass produced SOC which operates from -45 up to +125C by default, so we decided to design SOM module with STM32MP1XX SOC which to be pin to pin compatible with A13-SOM and offer same interfaces and signals so it could be drop in replacement for A13-SOM without need to re-design the complete product.

As you can see for STMP1-SOM we decided to put the SOC on opposite side of the connectors, this allow if necessary to add aluminum heatsink without interference with mainboard.

Also we add AXP209 PMU which allow lower power operating modes and LiPo battery backup and operation on battery only which is missing in the original A13-SOM.

STMP1-SOM will be offered with three SOC choices STM32MP151, STM32MP153 and STM32MP157.

The prices will start from EUR 15 for the non industrial grade memory which are similar to A13-SOM and EUR 18 for the industrial grade -45+85C memory version.

We expect first STMP1-SOMs to be available in July 2020.
