EmbedMatrix is a scalable, modular embedded matrix platform designed for distributed sensing, multi-node control, and mesh-capable IoT deployments. Built around the STM32F031K6T6 ARM Cortex-M0+ MCU, each EmbedMatrix node is a self-contained, hot-swappable unit that snaps into a shared backplane bus — enabling you to build sensor grids, actuator arrays, and telemetry networks from 1 node to 64 nodes without redesigning hardware.

EmbedMatrix: common questions

What microcontroller does the EmbedMatrix use?

The EmbedMatrix is built around the STM32F070CBTx, from the STM32 family.

How big is the EmbedMatrix PCB?

The EmbedMatrix measures 53 × 73.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the EmbedMatrix?

45 components, from 16 distinct parts. The full bill of materials is listed on this page.

Where can I download the EmbedMatrix design files?

From the MAHESH-THILAK-K/ADDITIONAL-PROJECT repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the EmbedMatrix design in my own project?

Yes, under the terms of its Apache-2.0 license, which MAHESH-THILAK-K chose for the repository.

Can I test firmware for the EmbedMatrix without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
