Embedded Hardware

We design both analog and digital circuits and hardware for Embedded Electronics products. We take care to choose components that are reliable, easily available and have a Long Life Cycle.

• Industrial 4 to 20mA Current Loop 2 wire/3 wire /4 wire
• Industrial Analog output 0-10V, 0-20V etc
• Industrial Fault Protected Modbus over Rs485 upto 128 devices no repeaters
• Integrated SMPS 5V, 12V , 24V, Dual output
• IOT circuits, BLE tags + BLE reader, RFID Readers, GPS Tarcking solutions
• Stepper Motor Control, Encoders , Actuators , Triac LED Dimmer and Fan Speed control
• Li-Ion /LiFePo battery chargers, battery operated devices
• All micro-controller based circuits, displays , keypads, Touch screens

Embedded Firmware

We design and develop Firmware/Software for Embedded Electronics products. We focus on using Agile methods to reduce redesign and redevelopment costs, while also keeping bugs to minimum. Collectively we have a decade of experience in writing optimized, readable, well documented Embedded C code.
Over the course of few years we have developed reusable and easily portable stack for multiple modules. Following is the list of our Technology stack, that is robust and field tested.

• Communication Protocols - CAN , UART, SPI, I2C, Modbus
• User Interface on most popular 7 segment and 16x2 Displays
• User Interface on Resitive and Capactive TFT's built on event driven programming
• IOT circuits, BLE tags + BLE reader, RFID Readers, GPS Tracking solutions
• GSM/GPRS on Quectel, SIM800 and Ublocks modules
• Sensitive calibration 2 point/ 3 point/ 4 point for Weighing scales and Flowmeters
• External flash memory, SD card, MMC interface
• Analog output DAC/PWM based
• Bootloaders and Firmware over the air.
• Micro-controllers - ST, NXP , Texas , Megawin, AVR, Nordic

PCB Layout

Our PCB layouts are designed in Altium Designer Studio. We have developed a rich library of 3d models for most commonly used components.
Improper component placement can lead to a horde of issues that affect functionality, durability, manufacturability, and serviceability of the PCB. Hence, we focus on best component placement practices that ensure less rejection if assembled on pick and place machines.
We also pay attention to digital vs analog signal routing and heat sinking capabilities of the PCB. Following is the list of our PCB design skills.
Over the course of few years we have developed reusable and easily portable stack for multiple modules. Following is the list of our Technology stack, that is robust and field tested.

• Single layer/2 Layer/4 Layer boards
• High Power layout adherent to IPC-2221
• 3d modeling for Boards with Enclosure
• Standardized component orientation for Easy Hand assembly or Wave soldering

Component Assembly

We also take orders for PCB manual Assembly , both protoype boards and production boards.

• Minimum order quantity - 10
• MinimumSMD component soldering at 0.6 INR / Lead
• MinimumThough hole component soldering at 0.8 INR / Lead
• MinimumFRC Cable crimping/ JST Cable crimping etc
• MinimumCleaning charges as per board size
• MinimumTesting charges as per functionality
• MinimumPackagin and courier charges extra.

Front End Design and Development

With smarter Embedded Devices and IOT devices flooding the market, PC based Application has become the norm for these products. At stuffbits we develop such applications almost hand in hand with our Electronics products.

We develop front end applications on Open source java platform. Application can communicate with Embedded devices on industry popular Modbus protocol or also on USB bus.

Almost all our products are delivered with in-house developed Calibration and Configuration tools to speed up production.

We also design and deploy interactive websites for small businesses.

P.S : Our company website has been designed in-house
