@wanto220418

Hello, Your project is very interesting, I’m an electronics engineer with over 10 years of experience in an American-based automation company, designing industrial-grade control systems using CAN and CAN FD for machine and vehicle environments. Beyond schematic and PCB design, I am also capable of performing initial basic hardware testing to validate the design before handover. This includes: • Power-up validation (9–27V range) • Verification of buck/LDO rails (5V / 3.3V stability) • CAN/CAN FD communication test (loopback and two-node test) • ADC input validation (analog signal injection & reading stability) • Output driver validation (e.g., load test for high-side drivers up to specified current, PWM functional check) • Basic thermal observation under load I can document these results in a concise test report with measurements and notes to confirm that the boards meet the agreed functional requirements before production. My approach is always practical and industrial-oriented: robust power design, correct grounding strategy, proper protection (TVS, reverse polarity), and layout optimized for signal integrity and thermal performance. Best regards, Hendra

Designing a robust 12 V and 24 V industrial CAN based control system with joystick inputs on the transmitter and 5 A power outputs on the receiver is not a problem with the right automotive grade power and protection design. Well, what I can do for you as an electronics engineer with 8+ years of experience is design the complete TX and RX hardware around ESP32, industrial SPI ADC, and 3.3 V CAN transceivers, including protected 9 to 27 V power stages, EMI aware layout, proper grounding, and thermally safe 5 A per channel routing for the VN5016AJ outputs so the system is reliable in real machine environments. In fact, I have designed demanding embedded and power electronics including a custom security camera circuit design for a USA based requirement, a real time low power 8 bit SAR logic circuit at circuit level, and a high power dimmer around 10000 watts, so I am comfortable with noisy environments, mixed signal design, and production ready SMD PCBs.

@mahmoudralizadeh

Hello, I’ve carefully reviewed your industrial TX/RX controller concept based on ESP32 with CAN bus communication and high-current outputs. This is exactly the type of mixed-signal + power industrial design I usually work on. From your description, the key challenges are not only schematic capture, but: • Stable and low-noise acquisition of 8 analog channels in a 9–27V industrial environment • Reliable 3.3V CAN communication between TX and RX (deterministic timing) • Proper protection (reverse polarity, load dump, TVS, filtering) • Clean 5A/channel high-side outputs using VN5016AJ with correct thermal and copper planning • EMI-aware PCB layout separating analog, digital, CAN, and power domains My approach would be: 1️⃣ Define TX architecture (external industrial ADC via SPI + ESP32 + protected CAN stage) 2️⃣ Define RX architecture (CAN → ESP32 → VN5016AJ power stage) 3️⃣ Design robust 9–27V input stage (buck conversion + filtering + protections) 4️⃣ Deliver production-ready schematics, 2–4 layer industrial PCB layouts, BOM, Gerbers, pick & place 5️⃣ Propose enclosure strategy (off-the-shelf or custom) considering connectors, heat and serviceability I have experience with CAN-based industrial boards, power electronics routing, and designing for harsh environments where grounding and noise control are critical. Before aligning the final scope, I’d like to clarify a few points to ensure the architecture fits your real application: • What sampling resolution and accuracy do you expect for the analog inputs? • Is galvanic isolation required for CAN or IO? • Expected enclosure size constraints? • Operating temperature range? Once we clarify these, I can suggest a concrete technical structure and timeline. Looking forward to discussing the details ?

✅ Okay, I got what you want exactly. I am a senior embedded hardware engineer with over 10 years of experience, providing industrial PCB design, power electronics, CAN-based systems, and ESP32-based controller development. This project is very similar to my previous works. I recently designed a dual-board CAN-controlled hydraulic module running on 9–32V, with 6 high-side outputs (4A each), external 12-bit SPI ADC, and STM32 controller—fully DRC-clean and production assembled in 500+ units. I also developed an ESP32-based industrial joystick interface with 10 analog channels using an external ADC and cyclic 20 ms CAN messaging, including surge protection and common-mode chokes for long harness applications. ✅ So, I will divide your project like following: ⚡ System architecture & component selection (ADC, CAN transceiver, power tree, protection concept) ⚡ TX schematic + PCB layout with industrial analog front-end ⚡ RX schematic + high-current PCB layout with thermal and copper validation ⚡ Enclosure selection/design with mounting, connector placement, and STEP/STL delivery ⚡ Documentation package: Gerbers, BOM, PNP, wiring guide, and CAN topology notes 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
