Direct Insight Launches QSMP-15W Wireless SoM

Direct Insight has introduced the QSMP-15W, a compact QFN-style system-on-module (SoM) that integrates wireless connectivity with the industrial-grade STM32MP1 microprocessor platform for IoT and Industry 4.0 applications.

Developed in partnership with Ka-Ro Electronics, the QSMP-15W adds Wi-Fi and Bluetooth connectivity to the STM32MP1 architecture while maintaining a compact footprint suitable for space-constrained embedded systems.

Compact and high-performance architecture
The module is built around the STMicroelectronics STM32MP157C microprocessor, featuring a dual-core ARM Cortex-A7 processor running at 650 MHz combined with a 209 MHz Cortex-M4 coprocessor and an integrated 3D GPU.

The SoM integrates 512 MB DDR3L RAM and 4 GB eMMC flash within a compact 27 mm × 27 mm solder-down package with a height of just 2.3 mm. Its QFN-style pinout uses 100 edge pads with a 1 mm pitch, helping reduce electromagnetic interference while improving thermal performance.

Designed for industrial environments, the module supports an operating temperature range of −40°C to +85°C and operates from a single 3.3 V power supply.

Integrated wireless connectivity
Wireless capability is enabled through a Murata Type 2AE Wi-Fi and Bluetooth module, supporting dual-band 2.4 GHz and 5 GHz Wi-Fi (802.11a/b/g/n/ac) alongside Bluetooth 5.2 BR/EDR/LE.

The module incorporates the Infineon Technologies CYW4373E chipset, which uses advanced coexistence algorithms to optimize simultaneous Wi-Fi and Bluetooth operation.

The compact, shielded design makes the platform suitable for embedded applications such as industrial IoT systems, smart home devices, and connected edge computing solutions.

Development-ready platform
The QSMP-15W supports a wide range of interfaces including CAN bus, UART, SPI, I²C, audio, Gigabit Ethernet, SD, USB, and MIPI-DSI display connectivity.

To accelerate development, the module is supported by a dedicated Linux board support package (BSP) and a development kit that includes a Molex 2.4/5 GHz balanced PCB antenna.

The combination of integrated wireless connectivity, compact design, and industrial-grade reliability makes the QSMP-15W a cost-optimized platform for next-generation embedded and IoT systems.
