Embedded Systems & IoT

Embedded firmware, hardware and connected devices

We write the firmware, design the boards and build the apps that talk to them, so your device works as one product. You can start from an idea, a development board or an existing design, and you don't need to know which microcontroller you need.

Is this for you?

  • You have a product idea and need a working prototype to test or demonstrate.
  • Your prototype works on a development board and now needs a custom PCB.
  • Your device needs to send data to the cloud and to a web or mobile app.
  • Existing firmware is unreliable or hard to change.

What we deliver

  • 01

    Microcontroller firmware

    Firmware that reads sensors, drives motors and displays, and keeps devices responsive, written for the chip that fits your product's cost, power and connectivity needs.

  • 02

    Bare-metal & RTOS

    Low-level code with direct hardware access (startup code, interrupts, peripheral drivers and memory), or multitasking firmware on a real-time operating system when timing matters.

  • 03

    Raspberry Pi & embedded Linux

    Applications and services on Raspberry Pi single-board computers, and embedded Linux systems where a device needs networking, storage or a full software stack.

  • 04

    Prototypes to custom boards

    From Arduino-compatible and dev-kit prototypes that prove an idea, to schematic design, PCB layout and bringing up the first boards of your own hardware.

  • 05

    Sensors & peripherals

    Integrating sensors, actuators, displays and communication modules over the buses they use, and debugging the hardware-software boundary.

  • 06

    Connected devices & IoT

    Getting device data to the people and systems that need it: wireless connectivity, device-to-cloud messaging, and the web or mobile apps on the other side.

Frequently asked questions

I don't know which microcontroller I need. Is that a problem?

Not at all. Tell us what the device should do, how it is powered and how it connects, and we'll recommend a platform such as STM32, ESP32, AVR/Arduino or RP2040.

Can you take a prototype to a custom board?

Yes. We move proven prototypes from development kits to schematic design, PCB layout and bring-up of the first boards.

Do you build the app and cloud side too?

Yes. Device-to-cloud messaging over MQTT, and the web or mobile apps that show the data, are built by the same team.

Are there platforms you don't work with?

We don't currently offer PIC microcontroller development. For other platforms, ask us in the project form.
