Compact ESP-C3 Motor-Driver PCB

@Mahihassi

With an extensive background in electrical engineering and embedded systems, along with a Master’s degree specializing in IoT product engineering, I believe I'm the ideal freelancer for this compact PCB design project. My in-depth knowledge of microcontrollers like ESP32 and my proficiency in firmware development using diverse wireless stacks such as BLE and Wi-Fi puts me in good stead to retain full Bluetooth and Wi-Fi functionalities on the ESP-C3 module, ensuring seamless wireless control and OTA updates as required. Moreover, my experience with RF hardware design combined with specialized skills in squeezing mixed-signal designs into tight spaces brings significant value to this project. I am confident that I can create a PCB layout that effectively integrates the ESP-C3 Zero module, the TB6612FNG dual H-bridge driver, and an on-board 12V step-down supply within the required 45mm × 30mm dimensions with no compromises on component sizing for handling up to 2A continuous motor current. When it comes to designing PCBs for robotics platforms, precision motor control is key. Rest assured, my skills in robotics and motor control (FOC, PID) align well with your needs.

Hi I am an embedded systems engineer with over 16 years of experience. I have designed compact ESP32/ESP-C3 based control boards, motor-driver PCBs and buck-powered mixed-signal layouts where RF performance, thermal paths and manufacturability all need to fit in a small outline. For this board I would first lock the pin map around the ESP-C3 antenna keepout, motor PWM needs and the requested I²C/SPI/ADC breakouts, then route the TB6612FNG and 12 V to 3.3 V supply with short current loops, proper copper for the motor paths, labelled expansion pads and JLCPCB/PCBWay DRC rules. I can deliver KiCad or Altium files, Gerbers/drills, BOM with orderable parts, STEP model, design notes and a small ESP-IDF/Arduino reference firmware to blink, advertise BLE and run a motor test without brown-outs. A couple of details I would confirm before final layout are your preferred motor connector style, expected peak motor current, and whether you want USB/programming header on-board or via pads to save space. I can also support the bring-up revision after fabrication if needed. Please contact me to discuss details.

Hi, I can definitely help with this project. I have experience designing compact ESP32-based motor control boards and can create a custom PCB that integrates the ESP-C3 Zero, TB6612FNG motor driver, and a 12V-to-3.3V power supply within your 45mm × 30mm size limit. I’ll provide the complete schematic, PCB layout, Gerber/Drill files, BOM, 3D model, and design documentation. All free GPIOs will be broken out and clearly labeled, with dedicated I²C, SPI, and ADC expansion headers. The design will be DRC/ERC verified and include test firmware for BLE, Wi-Fi OTA, LED control, and motor operation. I can start immediately and deliver a clean, manufacturing-ready design. Looking forward to discussing the details.

@leonidye

Hi, I can design the compact ESP-C3 motor-driver PCB for your robotics platform, including schematic, PCB layout, Gerbers, BOM, STEP model, and basic reference firmware. I have experience with ESP32/ESP-C3 based control boards, compact motor-driver layouts, DC/DC power design, and JLCPCB/PCBWay manufacturing requirements, so I can keep the design within the 45 mm × 30 mm outline while still exposing the unused GPIOs clearly. For the design, I will place the ESP-C3 Zero carefully to preserve Wi-Fi/Bluetooth antenna clearance, route the TB6612FNG motor outputs with proper copper width/thermal relief, and design the 12 V to 3.3 V buck supply with sufficient filtering to avoid MCU brown-outs during motor startup. I will also break out I²C, SPI, ADC, and remaining GPIOs on labelled pads/headers, and provide screw-terminal or JST motor/output options depending on your preference. One technical point I will verify early is the real continuous-current requirement. The PCB will be checked with 6 mil/6 mil or better DRC/ERC rules, include clear silkscreen labels, and be prepared for direct fabrication. I can also provide simple test firmware to blink an LED, advertise BLE, and run a motor test sequence so the hardware can be validated quickly after assembly. I can start right away. Regards.

Hi, I can deliver your board as a complete, manufacturing-ready package — schematic, multilayer layout, and all production files — without the usual back-and-forth between designer and fab house. I have 14+ years of experience in PCB design and firmware development. I work daily in Altium Designer, KiCAD, and Eagle, and I own licenses for Altium and Eagle, so I can start immediately on your project. My background covers: • 2–16 layer PCB layout, high-speed routing, and controlled-impedance design • Mixed-signal boards, power distribution, and EMI-aware placement • Full deliverables: schematic, PCB layout, BoM, Gerbers, pick-and-place, ODB++, assembly drawings, DRC report, and 3D STEP model I previously worked at READA PCB Technology in Shenzhen as a PCB designer and production manager. That factory-side experience means my layouts are built for real manufacturing — correct clearances, sensible via strategy, and DFM/DFA checks before files go out the door. If you also need prototypes or small-batch assembly, I can coordinate PCB fabrication, PCBA, component sourcing, functional testing, and shipping through the Shenzhen network I know well from my time at READA. I am available to start right away and happy to sign an NDA before reviewing your design brief. Looking forward to your reply. Best regards, Ting
