KiCad Double-Layer PCB Design

@MuhammadUzair16

Hi, I am an embedded systems engineer with over 16 years of experience designing ESP32-based control electronics and taking consumer products from concept through production, including PCB layout, bring-up, and firmware support. I can turn your prepared KiCad libraries and documented pin mapping into a complete two-layer mainboard, first validating the schematic and power architecture, then laying out the mixed-signal, motor-control, SPI, and dual-I2C sections with careful attention to grounding, noise, thermal placement, connectors, and serviceability. I will deliver the complete KiCad project, reusable schematic/footprint/3D blocks, Gerbers, drill files, and BOM, with final design-rule and manufacturing checks. One important point to confirm: will the PCB carry the 48V/24V rails directly, or only control external isolated relay modules? I would be glad to discuss the design details and review your existing library and documentation.

As a seasoned electrical engineer, specializing in the area of circuit design and embedded systems, I am well-equipped to complete this KiCad Double-Layer PCB Design project for your DIY solar tracker. Not only do I have extensive experience with Arduino and the ESP32, but also with various other modules you've documented such as RTCs, EEPROMs, and I2C bus control - all of which feature in your project description. In terms of hardware familiarity, my skills certainly align with your project’s requirements. With a detailed understanding of motor control and analogue circuits, I can ensure the DC motors are driven correctly using the BTS7960 drivers on the specified GPIOs. I've got ample experience designing and working with power electronics, particularly relevant for management of your 48V/24V power rails. Moreover, a deep understanding of renewable energy combined with my successful history in PCB layout makes me the ideal candidate for this project, allowing me to distinctly place heat-emitting modules and manage the overall circuit meticulously. As a result-oriented professional who believes in delivering nothing but top-notch quality work, I assure you that my final deliverable will be ready for direct manufacturing. Based on my electronic design expertise, power electronics knowledge and my previous track record--you won't find anyone more qualified for this important role than me!

As a seasoned electrical engineer with vast experience in PCB design, I'm excited to take on your solar tracker project using the popular open-source KiCad platform. Over the past 8 years, I've honed my skills in circuit design using tools like Eagle, Altium, and EasyEDA, but KiCad is undoubtedly my specialty. With projects of this magnitude and complexity, my meticulousness and attention to detail will become our assets. Your detailed list of peripheral devices and functional requirements is precisely what differentiates my service. My fluency in using Wire/Wire1 for separate I2C buses (which will be integral for your two-axis solar tracking) along with managing GPIO/I2C mappings guarantees an efficient design on the ESP32-based mainboard that you already have. From TFT screen to SD card control and managing power rails to motor control via BTS7960 drivers, I am well-versed in creating circuit boards that maximize functionality within a given spatial constraint. In addition to PCB design and layout, which encompasses validating existing schematics based on your module library, my deliveries extend beyond just Gerber files and BOM. I provide complete blocks - schematic, footprints and 3D renders - a standard of excellence that you can expect from every aspect of our collaboration. Let's bring your solar tracker to life!

With over a decade of experience in the field, not only have I extensively worked with PCB designing, specifically using KiCad, but I have also covered a range of projects that align perfectly with your solar tracker development needs. My firm hold on the technical aspects including Microcontroller Programming and Electronic Development Boards with STM32 gives me an edge in understanding and executing complex designs. In fact, in one of my recent projects, I designed a PCB for controlling DC motors with ESP32 incorporating various electrical modules. The fact that you've already prepared a library of modules and documented the full GPIO/I2C mapping makes it easier for me to review and validate the schematic according to your specifications. The comprehensive yet meticulous approach that I bring ensures that all functional requirements are met while adhering to design rules and integration of heat-emitting modules - no detail is too small to escape my attention. Moreover, apart from delivering the complete electronic schematic for your main board and PCB layout inclusive of manufacturing files, my commitment to providing post-project support guarantees seamless usage even after the design phase is completed. Taking into consideration all these factors, partnering with me for your DIY solar tracker will ensure exceptional quality, dependability and on-time delivery. Let's turn your vision into reality together!

Mr. Gentleman, I have successfully crafted reliable circuits for both power supply conversions (DC-DC, AC-DC) and multilayer embedded systems. As a result, I am well-equipped to design your DIY solar tracker's PCB to suit the specific needs of your ESP32-based circuitry. Moreover, my experience with RF design extends to optimizing antenna performance for WiFi, Bluetooth, and even RFID applications. Since you mentioned employing capacitive touch TFT screens with ST7796S controller and FT6336U touch sensor in your project, my proficiency here could further solidify our comprehensive approach. With me on board, you can be assured of receiving not only manufacturing-ready Gerbers and BOMs but also a complete KiCad project enriched by my dedicated work ethic that refuses to compromise on quality or timelines. Let's connect and discuss how I can add value to your vision!

Hi there, I carefully reviewed your solar-tracker hardware requirements and can take the existing KiCad library, documented GPIO/I2C/SPI mapping, and validated peripheral list through to a complete production-ready ESP32 mainboard. I have strong experience with ESP32 hardware, mixed-signal PCB design, motor-control interfaces, I2C/SPI peripherals, ADCs, relay control, power-distribution circuits, TFT/touch interfaces, sensor integration, and KiCad. I am also familiar with the components and modules used in your project, including ST7796S/FT6336U displays, ADS1115, MCP23017, PCA9685, AS5600, MPU6050, PN532, BTS7960, DS18B20, RTC/EEPROM devices, and SD-card interfaces. I can review the schematic for electrical consistency, complete the PCB layout with proper placement, power routing, grounding, thermal considerations, connector access, and manufacturability, then deliver the full KiCad project plus Gerbers, drill files, BOM, and production documentation. Since your firmware, mappings, and module library are already prepared, I can move quickly and focus directly on hardware validation and PCB implementation. Just send me the existing KiCad library, mapping document, and mechanical constraints, and I can get started. Best regards, Samuel tshibangu

@tetianam8

⭐⭐⭐⭐⭐ This project is a good fit for a structured KiCad integration and layout workflow because you already have the firmware, GPIO mapping and module libraries prepared. I can focus on turning those validated blocks into a clean, manufacturable ESP32 mainboard without unnecessarily changing your architecture. I’ll first validate the provided module schematics, footprints, 3D models and GPIO/bus mapping, then build the complete main schematic and route the PCB around the actual electrical constraints. Key areas I’ll pay particular attention to: • Shared SPI routing for ST7796S TFT + SD with clean CS separation • Two independent I²C buses and their pull-up/termination strategy • Low-noise routing for the ADS1115/LDR/battery/anemometer measurements • AS5600/MPU6050/RTC/NFC sensor placement and interference • Separation of BTS7960/motor and 24/48 V relay switching from sensitive signals • ESP32 power, grounding, decoupling and programming access • Proper connector placement, thermal spacing and serviceability I’ll deliver the complete editable KiCad project, schematic, PCB layout, BOM, Gerbers, drill files and required 3D/mechanical data, following your existing library and design rules. Please send the existing KiCad library, mapping, design rules and board/enclosure dimensions. I can start by reviewing the supplied blocks and identifying any schematic or layout risks before committing the final routing.
