About Me

Engineer.
Builder.
Innovator.

I'm Namit Jain, an electromechanical engineer graduated from Vellore Institute of Technology with a B.Tech in Mechatronics and Automation. With 2+ years of hands-on experience in defense and aerospace, I've worked on servo systems, BLDC motors, surveillance drones, and battery management systems.

My work spans from designing axial flux motors that achieved 85% efficiency to developing military-grade drones for the Indian Army, and freelancing on robotic gantry systems for construction tech startups. I take engineering problems from first concept all the way to production-ready hardware.

I also volunteer for NGOs, establishing robotics labs in rural areas — because the best engineering builds people up, not just products.

Smartwatch PCB — Custom Wearable, 1 of 1

The main MCU is an ESP32-S3R8 (Espressif) — dual-core Xtensa LX7, Wi-Fi 802.11 b/g/n and BLE 5.0, with 8 MB embedded PSRAM. External flash is a W25Q128JVS (Winbond), 128 Mbit via SPI. RF antenna is a Johanson 2450AT18A100E chip antenna tuned to 2.4 GHz. The power path uses a TPS63001 buck-boost converter (Texas Instruments) paired with an MCP73831 single-cell Li-Po charger (Microchip) and a MAX17048 fuel gauge IC (Maxim) for state-of-charge tracking. USB connectivity is handled by a Same Sky UJ20-C-H-G-TH-P16-TR USB-C connector rated IP68, with USBLC6-2SC6 ESD protection (STMicroelectronics) on the data lines.

Motion sensing uses the BMA456 accelerometer (Bosch Sensortec) in a 2×2 mm LGA package. Haptic feedback is driven by a DRV2605L (Texas Instruments) connected to a JYLRA0825Z LRA motor. Audio input is an ICS-43434 MEMS microphone (TDK InvenSense). Timekeeping is handled by an RV-3028-C7 RTC (Micro Crystal), ±1 ppm accuracy. The LCD connector is a 13-pin JST GHR-13V-S. EMI filtering on the power rail uses a Murata BLM18PG121SN1D ferrite bead (120 Ω at 100 MHz). All passive components are 0201 or 0402 footprint. Board is DFM-compliant, case and strap fully customizable per unit.

Radion — PC Inside a Radio Enclosure

A functional PC built into a radio chassis. Nothing about the exterior indicates a computer is inside. The processor is an Intel N150 (4 cores, 3.6 GHz boost, 6 W TDP). RAM is 16 GB LPDDR5. Storage is 1 TB NVMe Gen 4. A 50 MP camera is embedded in the enclosure, not visible from outside. The system runs 24/7 without throttling. Custom PCB handles power distribution and thermal management within the radio form factor. DFM-compliant board design.

What Clients Say

★★★★★

I had the pleasure of supervising Namit during his internship, at AirBuddy Aerospace where he showcased exceptional skills and dedication in the realm of electric motor and controller design, particularly focusing on the innovative axial flux PCB motors. His depth of knowledge in this niche area was truly impressive, allowing him to approach challenges with creativity and precision.

★★★★★

We needed a precise EtherCAT-to-PWM interface board for the gantry arm in our robotic concrete 3D printer. Namit delivered a fully compliant solution — EMI/EMC cleared, RoHS certified — that cut our integration time in half. His understanding of motion control and PCB signal integrity is rare, especially at this speed of execution.

02
Design & Simulation
Schematics, PCB layout, 3D modeling, and SPICE/multiphysics simulations before fabrication.
03
Prototype & Test
First article build with full hardware testing — oscilloscope, VNA, thermal, EMI/EMC.
04
DFM Review
Manufacturing review with BOMs, Gerbers, and assembly drawings ready for any CM.
05
Delivery & Support
Final documentation, design files, and support through the first production run.
Working with us

Policies & Terms

Clear terms protect both sides. These apply to all engagements.

💵
Payment Structure
40% advance required before any work begins. 35% at prototype approval. Final 25% on delivery of all files. Engineering fees are separate from BOM and fabrication costs.
🔄
Revision Policy
2 rounds of revisions are included in every engagement. Additional rounds are billed at an hourly rate. New feature requests after design sign-off are treated as scope changes and quoted separately.
📦
BOM & Fabrication Costs
Component procurement, PCB fabrication, and assembly costs are billed separately from engineering fees. Clients may pay the CM directly or provide a procurement budget upfront. I do not absorb hardware costs.
🔑
IP & Ownership
All design files — Gerbers, schematics, source files — transfer to the client upon receipt of full payment. Prior to that, I retain all rights. NDAs are signed before any project details are shared.
🛠
Post-Delivery Support
30 days of support included after final delivery — covering design clarifications and minor queries. Production support, new batch BOMs, and ongoing changes are scoped as a separate retainer.
📋
Project Cancellation
If a project is cancelled mid-way, a kill fee applies based on work completed to date. The advance is non-refundable. Any components already ordered are billed in full regardless of cancellation.
Pricing guidance: All figures on the services section are engineering fees only and reflect project complexity, layer count, compliance requirements, and timeline. Final quotes are issued after the discovery call. International clients are quoted in USD — contact for rates.
