Digi ConnectCore MP13 SoM with STM32MP13 MPU embeds Wi-Fi 5 and Bluetooth 5.2 module

Digi International ConnectCore MP13 system-on-module (SoM) is powered by the just-announced STMicro STM32MP13 Cortex-A7 microprocessor and integrates a pre-certified WiFi 5 and Bluetooth 5.2 module for applications in the medical, smart energy, and industrial sectors.

The module is also equipped with up to 1GB RAM and 1GB SLC NAND flash, and exposes I/Os through LGA pads and/or castellated holes with interfaces such as dual GbE, USB 2.0, I2S and SPDIF for audio, CAN FD, analog inputs, and more. Contrary to the company’s earlier Digi ConnectCore MP15 based on STM32MP15 MPU, the MP13 does not provide multimedia functions, display, and camera interfaces.

Technical documentation is not online just yet, but the ConnectCore MP1 documentation should soon be updated for the MP13 module. Digi expects the module to be integrated into medical devices, industrial gateways, environmental test equipment, renewable-energy controllers, and EV charging stations.

The two STM32MP13 SoM namely CC-ST-DX58-ZK without wireless module and CC-WST-DX58-NK module with WiFi 5 and Bluetooth 5.2, and the CC-WMP133-KIT development kit can all be purchased on Mouser., Further information may be found on the product page and the announcement for Embedded World 2023.
