The Nagami from Austria-based NetCube Systems is a compact system-on-module that takes an unusual approach to embedded Linux design. Built around the Allwinner T113-S3 processor, the board adopts the standard mini PCIe form factor, measuring just 5.1 x 3 cm (2 x 1.2 inches), and includes an ESP32 co-processor handling WiFi 4 and Bluetooth 5.x connectivity.
The dual-core Arm Cortex-A7 processor runs at 1.2 GHz with 128MB of DDR3 memory embedded directly in the SoC. Storage comes from 4GB of onboard eMMC flash, while networking includes a 10/100 Mbps Ethernet PHY alongside the ESP32 wireless capabilities. The mini PCIe edge connector exposes a comprehensive set of I/Os including USB 2.0 OTG and host ports, multiple UARTs, two CAN 2.0B interfaces, I2C, SPI, and audio interfaces with I2S/PCM and S/PDIF support. A Qwiic connector provides additional I2C expansion options.
What sets the Nagami apart from competing T113-S3 modules like the MYiR MYC-YT113X is its mainline Linux support. The board was recently added to Linux 6.18 and works with mainline U-Boot, allowing developers to use standard Buildroot or Yocto builds rather than relying on vendor-specific Linux 5.4 BSPs. The documentation details software support and module specifications. NetCube Systems has mentioned two carrier boards in the Linux changelog, a basic evaluation carrier and a keypad carrier designed for intercom systems with PoE support, though details remain scarce.
Pricing and availability have not been announced, but the module is expected to appear on NetCube Systems' Tindie store when it launches. The company targets industrial automation, IoT, robotics, and general embedded applications, with an operating temperature range of -25 to 85°C (-13 to 185°F) when using a heatsink.
