HaneSOM – The Smallest Linux Compute Module


The HaneSOM module, designed by the Belgium-based DAB-Embedded is the tiniest Linux module. The module includes all of the essential components for running Linux on the same PCB. HaneSOM is a Microchip-based Arm Linux module with dimensions as 20 x 20 mm.

There are 69 I/O pins on the MPU. In addition, the module includes a 32 MB QSPI which is bootable and a MIC2800 PMIC. The PMIC is an LDO that allows the HaneSOM module to operate on a single 3.3V voltage rail. SD card I/Os, camera I/Os, and the RTC all have their own power rails on the board.

Let’s take a look at HaneSOM’s technical specifications

Using Linux and many digital interfaces such as LCD 24-bit RGB bus, 5MPix RGB camera interface, CAN 2.0/FD bus, Wi-Fi module, Google Coral AI modules, and more, the HaneSOM module lets the user construct as compact a device as possible. The module is ultra-compact, basing on the Microchip SAMA5D2 MPU with ARM Cortex-A5 (ARMv7 32-bit) architecture, which is widely supportive.

The display interface of 24-bit RGB LCD TFT features a capacitive touch controller. Furthermore, the module’s camera supports up to 5MP CMOS sensor support. For bare-metal applications and as a Linux-based system, the Microchip SAMA5D2 has excellent software support (Yocto, Buildroot and OpenWRT). Moreover, the QT can be used as a graphical user interface framework. The module attributes 128 MBytes DDR2 as its system memory. In addition, the DAB-Embedded HaneSOM provides 4 MB of QSPI flash as storage.

“Microchip has a long-term support plan for the SAMA5D2 family, and it guarantees stable delivery for long-life products. SAMA5D2 is a highly integrated MPU with various industrial and consumer protocols.” says the DAB-Embedded team about the MPU.

Human Machine Interface (HMI) applications such as edge computing, IoT gateways, smart cameras, are some of the applications for the System-on-Module. Furthermore, pricing at $37.00 you can avail your smallest Linux module.
