Your Questions, Answered with Engineering Clarity

We’ve collected the most frequently asked questions from system integrators, hardware engineers, and product managers working on Mini-PCBA-based designs. Whether you’re validating power input, planning I/O wiring, or reviewing BIOS behavior—this FAQ is structured to give you answers fast, with technical depth where it counts.

Technical FAQs

Your hardware questions, answered with engineer-level clarity.

This section focuses on the core technical questions our customers ask most when evaluating or deploying Mini-PCBA boards—from power input behavior to BIOS settings, I/O customization, and layout compatibility. Whether you’re building a fanless kiosk or an industrial gateway, these answers are grounded in real deployment experience, not just datasheets.

Power & Voltage

From wide-voltage support to ripple protection, this section answers key questions about powering your Mini-PCBA in fixed or mobile environments. Ensuring voltage stability is essential to protect sensitive embedded components and maintain uptime in 24/7 deployments.

Can I enable auto power-on or set boot delays?

Yes. The BIOS includes power recovery settings such as “Power-On After AC Loss” and optional boot delay timers. These are configurable via BIOS setup menu.

Do your boards support secure boot or TPM modules?

Select Intel and AMD platforms support secure boot. TPM headers (2.0) are available on most industrial-grade boards. Please check the specification sheet or request verification.

How do I reset the BIOS if something goes wrong?

You can reset BIOS to factory defaults by clearing CMOS via onboard jumper or pressing a defined hotkey during POST (usually F9 or F5, depending on model).

BIOS & Boot Settings BIOS

The BIOS is where you define behavior after power loss, customize boot timing, and enable security features. These settings are critical for systems deployed in remote or unattended locations, or where system recovery must be automated.

How many USB ports are available, and what types?

Most Mini-PCBA boards offer 6–10 USB ports, including USB 2.0, USB 3.0, and sometimes USB 3.2 Gen 1/2. Mix includes rear I/O and internal headers (Type-A or pin).

Are the COM ports RS-232 or TTL?

COM ports are configurable. By default, most boards support RS-232. On some models, BIOS or jumpers allow switching between RS-232 and TTL (or RS-485).

Can I request a custom layout for I/O headers?

Yes. For MOQ orders, we support custom I/O mapping, including USB pin headers, COM port type, or GPIO reassignments. Contact support to start a customization request.

I/O & Layout

I/O configuration is where your system connects to the outside world. This section covers USB types, COM settings, and how we support flexible header layouts for different device housings or integration needs.

Product Specs & Installation FAQs

Build with confidence. Know your board’s form, fit, and function

From dimension tolerances to thermal compatibility, this section covers the practical aspects of embedding a Mini-PCBA board into your product. Whether you’re planning enclosure cutouts, VESA mounting, or thermal strategy, these answers are designed to eliminate guesswork and reduce integration time.

Dimensions & Mounting

Understanding mounting hole positions, board thickness, and port clearance helps you avoid costly tooling revisions. This section provides precision detail for board fit and placement.

What are the standard dimensions of your Mini-PCBA boards?

Most boards follow the Thin Mini-ITX (170mm x 170mm) or 3.5” SBC form factor (approx. 146mm x 102mm). Full dimension drawings are available on request in DXF or STEP format.

Are VESA or DIN rail mounting options available?

Yes. Some boards support VESA mounting holes; others can be mounted via brackets or into custom trays. We can also provide OEM brackets for DIN rail integration.

How thick is the board, including connectors?

Typically 1.6mm PCB thickness. Including top-side I/O, expect a total height of 20–30mm depending on connector type. For low-profile builds, alternate headers may be specified.

BIOS & Boot Settings BIOS

The BIOS is where you define behavior after power loss, customize boot timing, and enable security features. These settings are critical for systems deployed in remote or unattended locations, or where system recovery must be automated.

How many USB ports are available, and what types?

Most Mini-PCBA boards offer 6–10 USB ports, including USB 2.0, USB 3.0, and sometimes USB 3.2 Gen 1/2. Mix includes rear I/O and internal headers (Type-A or pin).

Are the COM ports RS-232 or TTL?

COM ports are configurable. By default, most boards support RS-232. On some models, BIOS or jumpers allow switching between RS-232 and TTL (or RS-485).

Can I request a custom layout for I/O headers?

Yes. For MOQ orders, we support custom I/O mapping, including USB pin headers, COM port type, or GPIO reassignments. Contact support to start a customization request.

Thermal Management

Thermal failure is a silent killer. This section explains how to size heatsinks, position vents, and validate thermal loads in fanless environments or enclosed systems.

Can your boards operate without active cooling?

Many of our models are rated for fanless use. They use low-power SoCs and copper-pour thermal zoning. Always test full-load temps in your specific case. Passive heatsinks are recommended.

What’s the operating temperature range for typical boards?

Standard models support 0°C to +60°C. Industrial models may reach -20°C to +70°C or even -40°C to +85°C upon request.

Do you offer thermal simulation or heat spreader support?

Yes. We offer guidance on airflow, heatsink selection, and thermal pad placement. For volume orders, we can assist with heat spreader co-design or thermal validation reports.

Shipping & After-Sales FAQs

From prototype samples to large production batches, here’s what to expect when ordering Mini-PCBA boards from miniitxboard.

What is your typical lead time for standard boards?

Standard boards are typically shipped within 7–15 business days. Lead time may vary slightly depending on order volume and stock availability.

What is the Minimum Order Quantity (MOQ)?

For in-stock standard models, there is no MOQ. For custom-configured boards (e.g. BIOS mods, I/O changes), MOQs usually start at 100 pcs depending on complexity.

Can I request engineering samples for testing?

Yes. We support pre-production sampling. You may request 1–3 units for lab or integration testing, with partial refund upon full PO.
