Precision Engineering Partner
INTI builds working hardware prototypes around defined product goals and operating conditions, connecting circuit and PCB design, firmware, Android/iOS apps, and web/server integration. At the production stage, we directly manage parts sourcing, SMT and assembly through partner manufacturers, inspection, and the overall production process.
End-to-end development scope
Capabilities
We do not treat circuits, firmware, and software as isolated tasks. We connect the flow from a powered board to data, Android/iOS apps, web/server interfaces, and production management.
We shape the circuit around product constraints and prepare PCB, BOM, and Gerber files that manufacturers can use.
Schematics, PCB, BOM/Gerber
We develop firmware for STM32, ESP32, nRF, AVR, PIC, and other 8-, 16-, and 32-bit MCUs, as well as TI DSP platforms.
Control logic, drivers, communication firmware
We choose communication methods such as BLE, Wi-Fi, LoRa, and LTE Cat-M1 around field constraints, then check node and gateway links.
Wireless nodes, gateways, communication logs
We connect device data to Android/iOS apps, mobile web, web dashboards, APIs, server storage, and CSV download flows.
App screens, APIs, data flow
We reliably read and log temperature, distance/ToF, Hall, ADC/DAQ, optical, current/voltage, and battery data.
Sensor interfaces, measurement logs
We tune battery operation, charging, sleep modes, power measurement, and long-run testing for real field use.
Power data, low-power operating conditions
We implement core board behavior such as motor control, state machines, watchdogs, and PDM/I2S audio input/output.
Control firmware, audio/motor integration
We connect board bring-up, functional tests, long-run logs, and certification test response with production data, parts sourcing, partner-based SMT and assembly management, and inspection.
Test results, production items
Development Scope
We define the hardware, firmware, Android/iOS app, and web/server scope included in prototype development from the product goal, operating environment, key functions, and schedule conditions. At the production stage, we also review sourcing, SMT, assembly, and inspection scope.
Clarify product purpose, operating environment, power, communication, certification, and schedule constraints.
Separate board, firmware, Android/iOS app, web/server, and gateway boundaries while identifying technical risk early.
Design circuits, PCB layout, BOM, Gerber, DFM, power/charging, and sensor interfaces.
Implement MCU control, communication, sensor processing, power management, state machines, and update paths.
Connect Android/iOS apps, mobile web, REST APIs, dashboards, data storage, and download flows.
Power up real boards and reduce early defects through measurement tools and logs.
Check functions, power behavior, communication stability, and long-run operation logs.
Support design reviews for KC, RF, EMI, and EMC requirements and prepare certification test support documents.
After prototype review, we prepare BOM, Gerber, CPL, and SMT data with inspection procedures, then manage parts sourcing, partner-manufacturer orders and assembly, inspection, and production.
Support field issues, firmware updates, feature improvements, and follow-up version transitions.
Process
Hardware prototype development depends on reducing risk in the right order. INTI moves through requirements, design, implementation, integration, and real operation checks step by step. At the production stage, the work continues into manufacturing data and production planning.
We define the product goal, operating conditions, constraints, and risks that must be verified.
Output: Requirement brief
We decide the MCU, communication, sensors, power, Android/iOS app, and server scope, then set the development order.
Output: System architecture
Hardware design and firmware implementation move together to reduce review issues before board fabrication.
Output: PCB and firmware
Device data is connected to Android/iOS apps, web views, servers, and file download flows.
Output: App screens, API, data flow
Board bring-up, functional tests, power measurement, and communication logs confirm real operation.
Output: Test logs
After prototype review, we organize certification test support documents, BOM, Gerber, SMT data, inspection steps, parts sourcing, and production plans.
Output: Manufacturing data and production plans
Track Record

PCB Design
Custom PCB design for measurement hardware, including manufacturing files and firmware integration requirements.
Healthcare Device
Battery-powered product work covering display UI, pressure and drive control, power management, and production data.
Partnership
Our collaboration is built around prototypes that run on real boards and production-stage work that continues from the same development path.
Connected Scope
We connect circuit, PCB, firmware, Android/iOS app, web/server, and operation checks as one development scope.
Board-Level Check
Real board bring-up, logs, power measurement, and long-run tests are used to reduce technical risk.
Production Management
After prototype review, INTI prepares BOM, Gerber, and SMT data, test procedures, and certification test response, then directly manages parts sourcing, PCB fabrication and SMT/assembly through partner manufacturers, inspection, and the overall production process.
FAQ
Answers to common questions before a project starts. Use the inquiry form to send us a brief project outline.
From the earliest idea stage, even before requirements are organized. We start from the product goal and operating environment, then propose a staged development plan across hardware, firmware, Android/iOS apps, and web/server scope.
Yes. We take partial scopes such as circuit/PCB design only, firmware only, or app/server integration only. Many projects also start from existing products, such as board improvements or firmware maintenance.
We work across 8-, 16-, and 32-bit MCUs and DSP platforms without being tied to a single manufacturer. Where development tools and datasheets are available, we support new firmware development, existing-code analysis, and feature improvements.
It depends on the scope and parts availability, but a single-board prototype is typically planned in weeks to months, from circuit design to operation checks. We review schedule risks during the requirement stage and present a staged timeline.
We manage the production stage directly. INTI prepares BOM, Gerber, CPL, and SMT data and sources parts, while PCB fabrication and SMT/assembly run through partner manufacturers. Orders, schedules, inspection, and production are managed by INTI end to end.
We are not a certification agency. Instead, we support design reviews that consider KC, RF, and EMI/EMC requirements, and prepare certification test support documents to reduce rework during certification testing.
