A small adapter board like this should be quick to manufacture when footprints, pin-1 orientation, and JLCPCB outputs are handled cleanly. Well, what I can do for you as an electronics engineer is design the 2-layer PCB in KiCad with the exact Samtec CLM-110-02-H-D (JLCPCB C3320770), the 1×10 2.54mm header, all required resistors/caps, and the exact pin mapping and silkscreen labels you listed. In fact, I designed a high power 10000 watt LED dimmer for a UK client and I also built an 8 bit SAR ADC logic in Cadence, so I’m used to strict pin mapping, layout discipline, and production-ready file exports.

@Kristsp

Hi! I can design PCB according to your description and make sure files are ready for JLCPCB ordering. J2 wire header would most likely be 2.54 mm through hole part that would be soldered by JLCPCB or just footprint (drill holes) where you would solder it by yourself. Do you need any mounting holes on PCB? Description says 2.54mm 1×10 header for Dupont wires (Raspberry Pi wiring) but it seems connections does not follow Raspberry Pi pinout, but probably it will be connected to matching Rpi pins by wires.

@zszabo

Buna, With over 20 year of experience in electronics design, I can provide you the deliverable CAD and gerber files for production at JLCPCB. You may have a look on my past work on ArtroMED-Elektro site. If You are interested, dont hesitate to contact me. All the best ! Z

@yaroslavmark

✅ Okay, I got what you want exactly. I am a Senior PCB Design Engineer with over 10 years of experience, providing high-speed PCB layout, embedded hardware design, and JLCPCB production-ready documentation. In my opinion, the cleanest way to implement this adapter is to keep the routing short and direct between the Samtec CLM and the 2.54 mm header while placing the 33 Ω series resistors close to the signal source side for proper SPI integrity. I’ll also cluster the decoupling network tightly around the 3V3 pins of J1 with a solid ground plane on the bottom layer to ensure low impedance return paths and zero DRC issues at JLCPCB. This project is very similar to my previous works. Recently, I designed a 4-layer 0.8 mm pitch sensor breakout adapting a 24-pin mezzanine connector to a 2.54 mm debug header, including 6 controlled series resistors and compact decoupling within a 30 × 40 mm board outline. I’ve also prepared multiple fully assembled JLCPCB projects with LCSC parts mapping, CPL alignment fixes, and assembly validation for first-pass success. Via private chatting or meeting, I will provide the creative idea and good tech solution for your project and I want to discuss about the budget and timeline in detail. Best regards. Yaroslav

@AndreiVu

Hello contractor, I am an experienced PCB designer with almost 10 years of experience in Schematic and Layout design.

I have been working with JLC for over 5 years, both professionally and hobby. I am very familiar with the flow and the required file formats. The price includes the design, as well as initial support to order PCBs from JLC, if required. As deliverables, I will deliver the GERBER files, BoM and PnP files as well as the native KiCAD files, including a library with all the components. Looking forward to answer any questions you may have.

@ahmedy607

Hello, Please review my portfolio first — I’ve designed multiple small adapter and breakout boards prepared specifically for JLCPCB assembly. I fully understand the requirement: a 2-layer 25×50mm adapter that breaks out the Samtec CLM-110-02-H-D (JLCPCB C3320770) to a 1×10 2.54mm header, with exact pin mapping, required series resistors, pull-up, and proper decoupling placed close to the J1 3V3/GND pins. I will route all nets exactly as specified (including 33Ω series on SCLK/MOSI/MISO/CS, 10k pull-up on RST, and correct 3V3/GND distribution), ensure J1 Pin-1 marker matches electrical pin 1 (SCLK), keep J2-10 fully NC (no copper), and deliver a clean 2-layer layout with zero airwires and no DRC errors. Silkscreen will clearly label all J2 pins (3V3, GND, SCLK… NC) and include proper polarity/orientation markers. Deliverables will include JLCPCB-ready Gerbers + drill (ZIP), full BOM (with Manufacturer, MPN, and JLC part number for J1 = C3320770), Pick & Place (CPL), and KiCad source files. Before starting layout, I just need confirmation of the exact physical orientation of the Samtec connector relative to the 1×10 header (pin-1 direction and whether both connectors face the same or opposite board sides). Once confirmed, I can proceed immediately.

My extensive experience in circuit design, system integration and debugging will ensure a high-quality final product. KiCad, EasyEDA Pro and other EDA tools are to me as hands are to a builder- I'm highly proficient in every necessary aspect of PCB design. Using them, I've been successful in creating designs which not just work on paper but effeciently in the real world. These essential qualities enables me to design high-quality boards that meet your exact specifications and that never compromise on quality and precision. My deep understanding of electronics and neat soldering has become more rewarding over years as it's meant designs that avoid errors and latency issues due to bad routing or poorly designed decoupling circuits. I develop all aspects of projects- from concept to completion including Gerber + Drill (ZIP), BOM (CSV) for JLCPCB ordering, Pick & Place/CPL (centroid) files, and source project files. Most importantly, it's both my competency in working with open-source software such as KiCad which is preferred for this job along with my skillfulness with proprietary software like Altium and Eagle. I value collaboration deeply- seeking your insights at every stage of the process.
