FAQ
We have deep expertise in CAN 2.0A/B, CAN FD, LIN, FlexRay, and automotive Ethernet (100BASE-T1, 1000BASE-T1) protocols for in-vehicle networking. Our engineers design ECU interfaces, gateway modules, and network architectures that bridge legacy CAN/LIN buses with high-bandwidth automotive Ethernet backbones, ensuring deterministic latency and robust error handling.
We work with C-V2X (LTE-V2X PC5 from 3GPP Release 14, and 5G NR-V2X) and, for EU ITS-G5 markets, IEEE 802.11p. In the US, the FCC's 2024 rules move the 5.9 GHz ITS band to C-V2X and phase out DSRC. Our team designs and validates V2X modules covering V2V, V2I, V2P and V2N modes, with interoperability tested against the target OEM's stack and regional rules.
Our ADAS development process begins with a comprehensive sensor architecture definition, selecting the optimal combination of radar, LiDAR, cameras, and ultrasonic sensors for the target application. We design high-speed data acquisition boards capable of processing multi-sensor inputs in real time, implement sensor fusion algorithms on automotive-grade SoCs, and design the pipeline to the ISO 26262 requirements of the target ASIL.
We work to the ISO 26262 V-model: hazard analysis and risk assessment (HARA) to determine the required ASIL, then safety requirements flowed through the hardware and software architecture. We prepare the work products the programme needs, such as the safety plan, FMEA/FTA, dependent failure analysis and hardware architectural metrics, for the ASIL your programme requires; the functional-safety assessment is done by the OEM or an independent assessor.
We design automotive Ethernet solutions based on IEEE 802.3 standards including 100BASE-T1, 1000BASE-T1, and multi-gig variants, with careful attention to unshielded single twisted-pair PHY layout, connector selection, and EMC performance. Our designs incorporate TSN (Time-Sensitive Networking) profiles for deterministic communication and SOME/IP middleware to support zonal and centralized vehicle architectures.
We develop full-stack telematics control units integrating cellular modems (4G LTE/5G), GNSS receivers, Wi-Fi/BLE connectivity, and vehicle bus interfaces into compact modules built from AEC-Q-qualified parts. Our platforms support real-time vehicle diagnostics, remote fleet management, usage-based insurance data collection, geofencing, and cloud-connected analytics with end-to-end encryption.
Yes, we design electronics for both EVSE infrastructure and onboard charging systems, covering AC Level 1/2 and DC fast charging architectures; see our power electronics design service for BMS, DC-DC and charger power stages. Our designs address power factor correction, isolation topologies, pilot signal communication (SAE J1772, CCS, CHAdeMO), thermal management, and smart charging features including load balancing, V2G bidirectional power flow, and ISO 15118 Plug-and-Charge authentication.
We implement a defense-in-depth cybersecurity strategy aligned with ISO/SAE 21434 and UNECE WP.29 R155 regulations, covering threat analysis, risk assessment, and secure-by-design practices. Our solutions incorporate hardware security modules (HSMs), secure boot chains, encrypted communication channels, intrusion detection systems on vehicle buses, and secure diagnostic access controls.
We integrate a full spectrum of perception sensors including 77 GHz FMCW radar modules, solid-state and mechanical LiDAR units, multi-megapixel automotive camera systems with ISP pipelines, and ultrasonic arrays for near-field detection. Our hardware designs handle the high-bandwidth data interfaces these sensors require, including MIPI CSI-2, GMSL2, and automotive Ethernet.
We design OTA update architectures following Uptane framework principles with dual-bank flash memory layouts that enable safe A/B partition switching and guaranteed rollback capability. Our implementations include cryptographically signed firmware packages, delta update compression for bandwidth efficiency, update orchestration across multiple ECUs, and compliance with UNECE R156 requirements.
We develop connected car platform hardware including central compute modules, connectivity gateways, and domain controllers that serve as the backbone for digital vehicle services. Our platforms integrate cloud connectivity, edge computing, service-oriented architecture middleware, and standardized APIs for remote vehicle control, predictive maintenance, in-vehicle digital services, and data monetization.
We provide pre-compliance EMC design review and testing aligned with CISPR 25, ISO 11452, and OEM-specific standards. Our services include radiated and conducted emissions measurement, bulk current injection immunity testing, ESD characterization, and transient immunity validation per ISO 7637, with iterative design remediation before formal testing at an accredited lab.
Each project is quoted as a fixed-scope proposal: a statement of work with milestones, deliverables and pricing, sent within 3–5 business days of the discovery call. The price depends on the requirements, how mature the design is, technical complexity, the number of prototype iterations and the validation scope. Longer engagements can also run as a retainer or a hybrid of both. For budgeting before you contact us, our hardware development cost benchmarks and the PCB design, firmware and IoT cost guides give indicative ranges with their assumptions stated. They are planning ranges, not quotes.
It depends on the scope and on what already exists when we start. As planning ranges from our cost benchmarks: a single PCB layout takes 2–6 weeks per board and embedded firmware 4–16 weeks. A connected (IoT) product takes 3–12 months from concept to a production-ready design, and a regulated medical device 12–24 months to a 510(k) submission-ready package; from idea to mass production, a typical connected product takes 9–18 months. The proposal sets out a dated milestone plan, and you receive weekly progress updates during the project.
You do. Our contracts assign the intellectual property in the project work product (schematics, PCB design files, firmware source code and documentation) to you on payment, and we hand over the source files, not only fabrication outputs or compiled binaries. The exact terms are set out in the signed agreement for each engagement.
Yes. We sign a mutual NDA before any technical discussion of your project. Send your standard NDA or use ours; we return it signed within one business day.
Yes. We are based in Hyderabad, India, and work with product teams in India, the United States, the United Kingdom, Germany, Japan, Australia, the Middle East and other markets. Our office hours are 10:30–19:00 India Standard Time (UTC+5:30), Monday to Saturday, and we schedule design reviews across time zones, typically from US Pacific to Central European time. Japan is 3.5 hours ahead of India, so our first four hours overlap the Japanese afternoon. Prototypes and documentation ship by international courier such as DHL or FedEx. Our hardware outsourcing guide covers what to agree before an international project starts.
Yes. We prepare the manufacturing release package — fabrication and assembly drawings, the BOM with approved manufacturers, programming files and test specifications — and hand it over to the contract manufacturer (EMS) you choose. If you have not chosen one, we help you evaluate candidates through technical capability assessments and a pilot build. See manufacturing support.
No. Rapid Circuitry does not hold ISO 9001, ISO 13485 or other certificates. Our processes are aligned with ISO 9001:2015, and we design products to the requirements of the standards that apply to them — for example IEC 60601-1 and IEC 62304 for medical devices (with design documentation structured so your ISO 13485 quality system can absorb it) and IEC 61000 for EMC — and we specify IPC-A-610 workmanship classes for assembly. We prepare the product and its documentation for certification testing at accredited laboratories; the certificate or approval is issued for your product by the laboratory, notified body or regulator.
A short, non-confidential description of the product and what it must do (sensors, connectivity, on-device processing), the target production volume and unit cost, the markets and regulations it must meet (for example FDA, CE or FCC), your timeline, and what already exists: a concept, a proof of concept, schematics, PCB files or firmware. After the NDA, the next step is a 30-minute discovery call with the engineers who would work on the project, followed by the fixed-scope proposal. Send a project brief to begin.
