When software has to live in the real world.
Sixty8 develops custom firmware and embedded systems for products, devices, controllers, sensors, PCB-based systems, and connected hardware that need reliable software running directly where the physical world meets the digital one.
Embedded work often crosses firmware, PCB design, sensors, communications, applications, APIs, and cloud systems. Sixty8 can help connect those layers.
Embedded systems turn physical inputs into useful behavior.
The firmware is often the layer that decides what the hardware should do, when it should do it, how it should communicate, and what happens when conditions change.
From board-level logic to connected-device behavior.
Embedded projects can be focused firmware engagements or broader product-development work spanning hardware and software.
Custom Firmware
Purpose-built firmware for microcontrollers, controllers, sensors, devices, and specialized electronics.
PCB & Hardware Integration
Firmware built around custom PCB layouts, peripherals, interfaces, power constraints, device states, and hardware requirements.
Sensor & I/O Systems
Read, process, validate, and act on input from sensors, switches, controls, actuators, displays, and other hardware.
Connected Devices
Bluetooth, Wi-Fi, serial, device-to-device communication, network integration, and higher-level software connectivity.
Device Control & State Logic
Timing, sequencing, control loops, state machines, fault handling, alerts, recovery behavior, and operational logic.
Prototype to Product Support
Refine early firmware, improve maintainability, structure behavior, support testing, and prepare the software side for a more mature product.
Built where physical hardware needs custom behavior.
Bring a new electronic product to life
Develop the control logic, state behavior, inputs, outputs, communications, and firmware foundation around a custom PCB.
Control equipment or specialized hardware
Coordinate devices, sensors, triggers, outputs, timing, and local decision logic in a repeatable way.
Link the device to an application
Connect embedded hardware to mobile apps, web platforms, cloud systems, or custom APIs.
Capture and interpret real-world input
Read environmental, positional, electrical, mechanical, or user input and turn it into useful system behavior.
Move beyond proof-of-concept code
Turn fragile prototype behavior into a clearer firmware architecture that can be tested, maintained, and extended.
Connect hardware to software and interaction
Combine firmware with custom software, dashboards, AR/3D, displays, interfaces, and automation for a complete system.
The firmware is often only one layer of the final product.
Embedded work becomes much more useful when hardware, software, interfaces, connectivity, and the customer experience are designed to work together.
Build the applications, APIs, portals, dashboards, and business systems that interact with the device.
Create user-facing control panels, setup experiences, account tools, remote status, and configuration workflows.
Connect embedded hardware to spatial interfaces, displays, interactive installations, and emerging experiences.
Use device data as part of intelligent workflows, alerts, classification, predictive logic, or operational automation.
Start with the hardware behavior. Then make the software dependable.
Understand the device
We review the hardware, interfaces, operating conditions, inputs, outputs, constraints, and expected behavior.
Map the firmware logic
We define states, timing, communications, exceptions, dependencies, and the architecture required to support them.
Build the firmware
We implement device logic, drivers, communication layers, state control, input handling, and output behavior.
Validate real behavior
We test against actual hardware conditions, timing, edge cases, failures, communication paths, and device states.
Connect the full system
We bridge the device to applications, APIs, dashboards, cloud services, or other components of the larger product.
You do not need the entire hardware stack solved before starting the conversation.
I already have hardware or a defined embedded need.
Start with a Custom Project if the PCB, firmware requirement, device behavior, or integration need is already fairly clear.
Start an Embedded ProjectI have the product idea, but need help shaping the first version.
Kickstart can help establish priorities, scope, and what should be proven first before a larger engineering commitment.
Start With KickstartI need ongoing support around the connected workflow.
Leverage may fit when the device feeds broader operational workflows involving AI, automation, monitoring, or human follow-through.
