Cores — embedded & hardware

Where softwaremeets silicon.

The hardest systems are the ones you can hold. We build firmware, custom hardware, and connected devices engineered for real-world conditions — not lab demos.

What we engineer

01

Embedded systems

Firmware for microcontrollers and SoCs — efficient, reliable, and purpose-built. Low-level code that respects every byte and every milliamp.

02

Custom hardware

PCB design, schematic capture, and prototype builds. From concept to working board, we engineer every layer of the physical stack.

03

Connected devices

IoT systems that bridge physical and digital — sensor integration, wireless protocols, and edge computing in one cohesive product.

Microcontrollers

ARM Cortex-M

ESP32 / ESP8266

STM32 series

Arduino / AVR

Communication

UART / SPI / I2C

BLE & Wi-Fi

LoRa / LoRaWAN

CAN bus

Tooling

KiCad / Altium

FreeRTOS

Zephyr RTOS

PlatformIO
