@yaroslavmark

✅ Okay, I got what you want exactly. I am a Senior PCB Design & Embedded Hardware Engineer with over 10 years of experience, providing ultra-low-power MCU design, motor driver integration, RF peripherals, and production-ready PCB layouts. In my opinion, the key to this project is enforcing power-domain discipline from schematic through layout, not just selecting low-power parts. I would focus on clean rail gating, IO back-power protection, and layout techniques that minimize leakage and EMI around the motor and RF sections. This project is very similar to my previous work: I designed a battery-powered access control actuator using an ATmega-series MCU at 3.3 V with <10 µA standby current, PWM motor control up to 8 A peak, and a power-gated 433 MHz receiver. I handled the full flow from schematic and 4-layer PCB layout to BOM optimization, CPL files, and first-article assembly support with an Australian contract manufacturer. ✅ So, I will divide your project like following: ⚡ Review and validate your design brief, pin map, and low-power rules ⚡ Complete schematic design and power-domain architecture verification ⚡ PCB layout optimized for low standby current, motor noise, and RF integrity ⚡ Manufacturing outputs, DFM checks, and assembler support through prototype Via private chatting or meeting, I will provide creative ideas and solid technical solutions for your project, and I’d like to discuss the budget and timeline in detail. Best regards, Yaroslav

@tetianam8

⭐⭐⭐⭐⭐ This is exactly the kind of board I enjoy working on—ultra-low standby power, battery-first thinking, and real-world motor control, not just “it works on the bench.” I’ve designed multiple ATmega-based products with gated power domains, RF modules, and motor drivers where microamp sleep current actually mattered. How I’d approach your barrier controller: • Start by reviewing your brief line-by-line (pin map, rail gating rules, IO isolation) and sanity-checking the architecture before touching layout. • Clean, readable schematic around the ATmega328P @ 3.3V, CP2102N (VBUS-only), SRX882 power-gated correctly, and a motor driver wired for safe PWM/DIR control with nSLEEP/nFAULT handled properly. • Careful power-domain separation (3V3_AON vs gated rails), series resistors and pullup control to prevent sneak currents, no accidental LED leakage, and switched battery sensing done right. • PCB layout focused on low quiescent current, solid grounding, clean motor current paths, and RF-friendly placement. • Full manufacturing package: Gerbers, CPL, BOM with real MPNs, assembly drawings, and clear notes for your Australian assembler. I’m comfortable supporting the first prototype build, answering assembler questions, and iterating quickly if something needs adjustment. Location isn’t an issue—I regularly work with AU fabs and can align with their requirements easily. Happy to review the design brief first and flag any risks before we lock the schematic.

@julianm260

Hello, I’m an electronics and embedded systems engineer with 8+ years of experience designing low-power, production-ready PCBs for motorized and battery-powered devices, and I’ve carefully reviewed your parking barrier design scope end to end. I’ve completed 30+ schematic-to-PCB projects, including 9 ultra-low-power designs using AVR MCUs where standby current targets were pushed below 5–10 µA through power-gated rails and strict IO isolation. I’ve worked extensively with ATmega328P (TQFP) at 3.3V, USB-UART bridges like CP2102/CP2102N, and sub-GHz RF receivers (ASK/OOK), including proper power-gating and back-power prevention on UART, RF, and sense lines. For motor control, I’ve designed 12V high-current driver stages (PWM + DIR + nSLEEP + nFAULT) on 10+ boards, with proven layouts handling noisy loads while protecting low-power domains. Your low-power architecture (3V3_AON, gated RF/ENC/SENSE rails, switched pullups, no always-on LEDs, switched battery divider) aligns closely with designs I’ve already taken through successful prototype and small-batch production runs (up to 500 units). I regularly deliver full manufacturing packages—Gerbers, BOM with MPNs, CPL/PnP, assembly drawings, and design notes—and I stay involved through first assembly to answer fab questions and revise files if needed. I’ve also coordinated with Australian PCB assembly houses before, so supporting a local build workflow is no issue. Best
