I am building a proof-of-concept 2D LiDAR unit from the ground up and need a mainland-based embedded electronics engineer who can handle every step of the design and bring-up process. The goal is a compact indoor scanner that excels at obstacle detection and terrain mapping while holding tight, high-accuracy tolerances. What the work involves You will take the idea from blank sheet to working board: optical layout, high-speed signal processing, motor/galvo drive, power management, firmware, and a simple USB/TTL data interface that streams polar coordinates for fusion in my existing SLAM stack. Expect heavy use of Altium (or KiCad), STM32/ESP32 class MCUs, precise timing control in C/C++, and low-level debugging with J-Link or OpenOCD. I will handle mechanical housing once you define envelope and mounting points. Key expectations • Accuracy and repeatability must match typical 0.1° angular resolution and ≤3 cm range error across a 6 m indoor span. • Mapping frame rate: ≥10 Hz full sweep. • Sensor should self-calibrate on power-up and deliver clean packets over UART. • All design files remain editable; no locked libraries or black-box binaries. Deliverables 1. Complete schematic, PCB layout, and fabrication files. 2. Bill of materials with China-sourced components in mind. 3. Compiled and source firmware, plus flashing instructions. 4. Lab test report demonstrating accuracy targets met indoors. 5. Short video of the unit performing real-time obstacle detection and terrain mapping. Timeline is flexible if milestones are met; we can review progress after each hardware spin. If you have shipped LiDAR, ToF, or similar photonics projects before, let’s talk—I am ready to start immediately once I see a relevant portfolio.

Hi, I can develop your prototype 2D LiDAR sensor from concept to working proof-of-concept, including optical/electronics architecture, schematic, PCB layout, firmware, UART data output, calibration logic, and indoor accuracy testing. The best solution is to first finalize the sensing method, optical path, motor/galvo approach, range target, angular resolution, frame-rate requirement, MCU choice, power budget, and SLAM packet format. Then I’ll design the electronics around an STM32/ESP32-class controller, high-speed signal processing, motor drive, timing control, power management, and USB/TTL UART interface for polar-coordinate output. I’m comfortable with embedded hardware design, STM32/ESP32, C/C++ firmware, Altium/KiCad PCB layout, motor control, ToF/LiDAR-style sensing, UART protocols, calibration routines, J-Link/OpenOCD debugging, BOM sourcing, and prototype bring-up. Deliverables will include: * Complete schematic * PCB layout and fabrication files * BOM with China-sourced parts * Firmware source and compiled files * UART/USB data protocol * Self-calibration logic * Flashing instructions * Indoor test report * Accuracy and frame-rate validation * Demo video of obstacle/mapping output I’ll focus on an editable, transparent design with no locked libraries or black-box binaries, and a practical prototype architecture that can be improved through hardware spins.

Your 2D LiDAR proof-of-concept is exactly the kind of project I enjoy most — taking a blank sheet and turning it into a working board that hits tight tolerances. I've built similar high-precision sensing systems before, and I understand the care that goes into optical alignment and timing. Here's what I bring to this: → I've shipped a custom PCB with multi-sensor integration (ESP32-C3 air quality monitor) and a model railway servo controller with per-point calibration — both requiring precise timing and repeatability → I've worked extensively with STM32/ESP32, J-Link debugging, and C/C++ firmware for real-time control systems → Full stack capability: schematic, PCB layout, firmware, and bring-up — all in-house, so nothing gets lost between vendors → I have an in-house lab with oscilloscopes and logic analyzers ready for bring-up, and I'll deliver fabrication files formatted for Chinese fabs My approach: → First, I'll lock the optical layout and choose the sensor, motor, and MCU based on your 0.1° and ≤3 cm specs, then produce a schematic for your review → Next, I'll route the PCB (Altium or KiCad), write the firmware for precise timing and UART packet streaming, and bring up the board in my lab For this scope, the cost would be $12500.

HI, KINDLY READ THROUGH MY PROPOSAL The key challenge here is not simply combining a range sensor with a rotating mechanism, but synchronizing optical timing, angular position, acquisition, and motion so the reported polar coordinates remain accurate at a 10 Hz full-sweep rate. I would build the architecture around deterministic MCU timing, calibrated angle feedback, low-noise power domains, and a clean UART packet layer, then validate the complete chain against fixed indoor references. I’d structure bring-up around: • sensor/AFE timing and signal integrity • motor/galvo control with repeatable angular positioning • STM32/ESP32 firmware, calibration and packet streaming • Altium/KiCad design, prototype testing and measured error characterization One important point is separating 0.1° angular resolution from absolute angular accuracy, since both need independent validation to achieve the 3 cm range target. What ranging principle are you using, and is the optical receiver/laser already selected? What sweep mechanism and target scan geometry are you considering? PLEASE INITIATE A CHAT if you'd like to review the implementation details before we begin.

I have 35 years of experience in electronics design. I have experience in Hardware and embedded design. Do you need 360 degree vision? I am also proposing using a LED array to get rid of the need for spinning motors and mirrors. Due to the nature of this project and from my experience, it cannot be done in a short space of time. I am surprised at the time proposed by current bidders. The possibility of a budget overrun is high and needs to be accommodated My Bid excludes all component/Hardware costs.

Dear Client, A 2D LiDAR like this will live or die on timing accuracy, optical alignment, receiver noise, motor control and calibration—not just whether the MCU can read a distance sensor. I have 11+ years of electronics experience and 500+ completed assignments involving precision sensing, STM32/ESP32 systems, high-speed signals, motor control, power design, multilayer PCBs and prototype bring-up. I can take this from architecture to schematic, PCB, firmware, USB/UART streaming, calibration and lab validation. For the first spin, I would lock the ranging method, optical path, scan mechanism, timing budget and signal-processing chain before PCB design. The 0.1° resolution, ≤3 cm error over 6 m and ≥10 Hz sweep rate need to drive the architecture from day one. Main risks are detector noise, timing jitter, motor/galvo repeatability, optical crosstalk, ambient-light interference and calibration drift. Approach 1. Architecture, optical/electrical interface, timing and component selection 2. Schematic, PCB, firmware, motor control and UART/USB packet format 3. Bring-up, calibration, accuracy testing, source files and test report Please share the ranging principle, scan mechanism, target PCB size and whether optics are already selected. Best regards, Avi Gupta Quality is never an accident
