Engineering Support for Your Hardware Designs
Need to modify an existing ICDigest design or create a new hardware design for your application?
ICDigest provides practical hardware design services focused on schematics, component selection, circuit modifications, and custom electronics design.
Whether you need a small change to an existing design or a completely new circuit, we can help turn your requirements into a practical hardware design.
[ 🔧 Modify a Design ] [ 🛠️ Request a Custom Design ]
🔧 Modify a Design — From $15
Need a change to an existing circuit?
Already found a Design Block or ICDigest project that is close to what you need?
We can modify the existing design according to your requirements.
Typical modifications
- Change input or output voltage
- Replace an IC or module
- Add or remove a protection circuit
- Change connector type
- Add additional inputs or outputs
- Modify communication interface
- Change relay or switching requirements
- Add sensors or monitoring circuits
- Adapt the circuit for a different MCU or module
- Modify the circuit for your specific application
What you receive
Depending on the requested modification:
- Modified schematic
- Updated component selection
- Updated BOM
- Updated KiCad project files
- Design notes explaining important changes
Starting at $15
The final price depends on the complexity of the requested modification.

🛠️ Custom Hardware Design — From $49
Need a completely new hardware design?
If you have a hardware requirement but don’t have a complete circuit, we can help design it from the ground up.
We focus on practical and reusable electronics designs rather than unnecessarily complex solutions.
What we can design
Examples include:
- Power supply circuits
- Protection circuits
- Sensor interfaces
- MCU-based controller boards
- Relay and MOSFET driver circuits
- CAN / RS485 / UART interfaces
- IoT hardware
- Industrial interface circuits
- Measurement circuits
- Battery-related circuits
- Motor-control interfaces
- Communication interfaces
- Custom embedded hardware
- Other application-specific electronics
What you receive
Depending on the project scope:
- Circuit architecture
- Schematic
- Component selection
- BOM
- KiCad project files
- Design notes
- Recommended alternatives where appropriate
PCB layout, firmware, enclosure design, testing, and other engineering work can be discussed separately depending on project requirements.
Starting at $49
The final price depends on the complexity, requirements, and scope of the design.

How It Works
01 — Submit Your Requirements
Tell us what you need.
For example:
“I need a 24 V input to 5 V/3.3 V power supply with reverse-polarity and overvoltage protection.”
Provide as much information as possible, including:
- Input voltage
- Required outputs
- Load/current requirements
- Interfaces
- Main components, if any
- Application
- Special requirements
02 — Requirements Review
We review your requirements and determine the scope of the work.
For custom designs, we’ll confirm the expected deliverables and price before starting.
03 — Design
The circuit is developed using practical engineering considerations such as:
- Component availability
- Electrical requirements
- Protection
- Power requirements
- Interface requirements
- PCB implementation
- Component alternatives
04 — Delivery
You receive the agreed design files and documentation.
Depending on the selected service, this may include:
- KiCad schematic
- KiCad project
- BOM
- Component information
- Design notes
What We Don’t Promise
ICDigest services are intended for engineering design and development support.
Unless specifically included in the project scope, the service does not automatically include:
- PCB manufacturing
- PCB assembly
- Enclosure/mechanical design
- Firmware development
- Certification
- EMC/EMI certification
- Production validation
- Safety certification
- Mass-production support
These requirements can be discussed separately for suitable projects.
Need Something Specific?
Not sure which service fits your requirement?
That’s okay.
Send us your requirements and we’ll review the request and determine the appropriate scope.

Frequently Asked Questions
Can you modify an existing ICDigest Design Block?
Yes. If the requested change is within the scope of the existing design, we can modify the circuit according to your requirements.
Does the $15 modification price include any modification?
No. $15 is the starting price for relatively simple modifications. More complex changes may require a higher price.
Does the $49 custom design price include a complete PCB?
No. $49 is the starting price for custom hardware design work. PCB layout and other engineering work depend on the project scope.
Can I request a specific component?
Yes. You can specify preferred ICs, modules, sensors, connectors, or other components. We will consider them when developing the design.
Will I receive the KiCad files?
Where KiCad files are included in the agreed scope, you will receive the corresponding project files.
Can I use the resulting design commercially?
Commercial usage depends on the agreed project terms and applicable licensing. The licensing terms will be communicated for the specific project.
Do you provide hardware testing?
Testing is not automatically included. If hardware testing or prototype validation is required, it should be discussed as part of the project scope.
How do I start?
Submit your requirements through the appropriate service request form. We will review the request and confirm the scope before starting the work.

One recommendation for your actual WordPress page
I would not put the payment button immediately next to the $49 service.
Use this flow:
Service page → Request form → You review requirements → Confirm price → Payment → Design work
For the $15 modification, you can eventually make the process more direct:
Select Design → Describe Modification → Payment → Work begins
This protects you from someone paying $49 and then expecting a complicated 2-week hardware project.
Also, I would keep the future services you mentioned off this page for now. Once you are ready, you can add:
- 🔄 Component Alternative
- 📋 BOM Review
as additional service cards without redesigning the whole page.
