PCB Design and Layout Jobs

I have a small home-automation module that needs a reliable touch interface, so the task is to engineer a 5 V circuit around the TTP223 that cleanly switches between high and low digital levels whenever it is touched. Precision in sensitivity and long-term stability matter more to me than squeezing out the very last microamp, yet the design should still sit comfortably in standby without wasting power. Key expectations • The sensor must tolerate normal household electrical noise without false triggering. • Output logic levels must be directly MCU-friendly (TTL/CMOS, active-high preferred). • Component count should stay minimal; surface-mount parts are fine. • Any necessary debounce or filtering should happen in hardware rather than firmware. Deliverables 1. ...

For an R&D platform based on the SAM E54 Xplained PRO, we would like to make several (starting with 6) plug-in boards. The boards should be placed on one of the 3 headers of the Xplained. We have divided boards into 3 categories. Power supply, DCD converters (±48V or +40V or ±24V, 3V3, VREF 2.5, 1.25V, etc.). Driver OUTPUT User Interface and related For the first 4 boards (option 1 and 2), there are already schematics that can be used. These are already R&D PCBA files in use, but now we want to split them into partial boards as well. User Interface boards could be very simple, like a button, LED, header, screw terminal, etc. On request, new plug-in boards will need to be designed and created. All of this must be done with a program that is comp...

I need the existing 433 MHz transmitter board—built around a GD32 MCU and RD RF module—re-laid without altering the RF front end or protocol so it continues to pair seamlessly with the current firmware of the receiver. The primary goal of this spin is better build quality, with particular attention to two areas: tighter precision in signal transmission and improved on-board heat management. The board still has to accept 12 – 24 V trailer-plug power (including load-dump and transient spikes) and regulate it cleanly down to 3.3 V for the MCU. The present protection and buck stage work, but component placement and thermal performance can be improved. Some components are locked in for compatibility, and I will supply you the short list during kickoff; everything else may be ...

I want to create a clean, classic-looking digital watch that quietly packs solid fitness features behind a minimal façade. The styling should stay timeless—thin case, simple dial, neutral colors, no flashy bezels—yet the internals must handle three core tasks: • Continuous heart-rate monitoring • Accurate step counting throughout the day • Automatic sleep tracking each night Your job is to design and prototype the complete device, covering electronics, firmware, enclosure and strap geometry. Low-power components, efficient firmware and a straightforward two-button or touchscreen-tap interface will keep the user experience elegant and the battery life sensible. Please deliver: • Schematics, PCB layout and full BOM • Embedded code with c...

I need a complete hardware design for an ESP32-C6 Dual CAN carrier board that will sit at the heart of a new communication device. The board must do three things: • Data logging – capture and store CAN messages locally. • Wireless communication – push that data over Wi-Fi 6 / BLE without relying on an external gateway. • Sensor integration – leave headers or footprints that let me tap additional lines and inject CAN messages from attached sensors. At this stage I am looking for a finished set of design files: schematic, clean PCB layout, BOM with part numbers that are actually in stock, and the usual Gerber/ODB++ outputs so my fabricator can run a quick prototype. You’re free to work in KiCad, Altium, or another mainstream tool as long as the fi...

Key requirements: - Lightweight and handheld - Compatible with 12v Milwaukee battery - Replaceable tips Ideal skills and experience: - Background in tools/electronics - Experience with battery-powered devices - Prototyping skills I have the components i want to use and design of product, at next faze to make it real life

我正在启动一款面向家庭环境的小型机器人项目，目前处于“初步需求”阶段，核心目标是让它能够自然地对话与陪伴家人。机器人需要具备稳定的语音识别能力，并在接收到指令后以三种方式做出回应：说话反馈、执行简单动作以及在屏幕上显示信息。 从技术角度来看，整机需要基于自主设计的 PCB，主控可采用 ARM 或 RISC-V 架构的嵌入式方案；还要集成基本环境传感器，并预留扩展接口以便后续添加更多模组。我希望你能主导硬件原理图与 PCB 设计，完成底层固件的快速原型，实现与传感器、语音麦阵列及小尺寸显示屏的驱动联调，并给出可靠的硬件测试方案。熟悉 AI 加速器或边缘计算模组的经验会非常加分，因为日后有计划将部分语音与推理任务本地化。 交付物需包括： • 机器人硬件整体架构图 • 可生产的 PCB Gerber 与 BOM • 嵌入式固件原型（含语音识别接口、动作与显示控制逻辑） • 简易测试工装与测试用例文档 • 开机演示视频或现场演示，证明设备能在家庭场景下完成对话并做出多模态回应 我期待与你一起把这位“家庭伙伴”从概念变成可握在手中的真实设备。
