Conclusive Engineering has introduced the KSTR-IMX93 on Kickstarter, a Linux-capable SBC integrating Wi-Fi 6, cellular IoT, Bluetooth LE 5.4, Zigbee, Thread, GNSS, Gigabit Ethernet, CAN-FD, and PoE in a compact 110 × 55 mm design.

The platform is built around NXP’s i.MX93 application processor, equipped with two Arm Cortex-A55 cores running up to 1.7GHz and a Cortex-M33 subsystem for latency-sensitive tasks.

Memory options range from 512MB to 2GB of LPDDR4/LPDDR4X, accompanied by up to 128GB of eMMC and a microSD slot for removable storage.

Wireless functionality is provided by three Nordic Semiconductor components. According to the specifications, the nRF5340 delivers Bluetooth LE 5.4, Zigbee, Thread, and Matter-readiness.

The nRF9151 introduces LTE-M, NB-IoT, GNSS, and DECT NR+; and the nRF7002 enables dual-band Wi-Fi 6. This configuration allows the SBC to support multiple wireless standards without stacking additional modules or expansion boards.

Wired interfaces include up to two Gigabit Ethernet ports, CAN-FD, and support for IEEE 802.3af Power-over-Ethernet. Expansion options consist of a Raspberry Pi–compatible GPIO header as well as MIPI-DSI, MIPI-CSI, USB-C OTG, UART, I2C, SPI, and ADC inputs.

The company highlights support for Ubuntu, Yocto, and Buildroot, allowing developers to choose between rapid prototyping and production-oriented distributions. Zephyr RTOS is available on the Cortex-M33 subsystem and on Nordic’s wireless chipsets.

KSTR-IMX93 Pinout

Security features include NXP’s EdgeLock Secure Enclave for authenticated boot and trusted execution, with an optional 0.5-TOPS NPU available for tasks such as anomaly detection or lightweight vision inference.
