PCB designer and Embedded Programmer

Highly experienced in designing custom built projects in fields of electronics for more than 7 years. In house facility for PCB deigning and hardware assembly. Experienced in designing multi-layer boards for microcontrollers microprocessors FPGA and APSOCs. Experienced in working with all the variants of Arduino and ESP series. Has built custom Data loggers, Surveillance systems, Process controllers for Industrial purposes. Following are the deliverables that We can provide you with: 1. PDF: Schematics, PCB Artwork, 3D view of PCB 2. Source files: Schematics and PCB file in Altium 3. 3D step file of the PCB 4. Gerbers 5. NC drill files 6. BOM made compatible with Verified vendors and suppliers like Mouser, Digikey and JLC. which makes the BOM reliable and consistent over long duration of time 7. Firmware/Software/Codes/Sketches 8. Prototypes and mass production. We intently keep our BOMs compatible with most popular vendors on the market like Mouser, Digi-Key, LCSC and JLCPCB, that helps you to get a comparative study of the components available and speed up the prototyping and/or mass production process. While selecting the components we also personally ensure that the components are available in the market for longer duration and is also stable in the market, so you do not need to worry about the components in your design going out of the stock or becomes absolute.

Designed around ESP32 for application of Smart Pen this system measures just 10mm X 30mm Has builtin one programmable LED. Battery charging and Battery charging Indication alongwith Battery protection circuit. Has 0.91" OLED display (Not installed on PCB in images because images were taken prior to assembling the display. One image shows the display that will be assembled on this PCB). Working: This system is supposed to go inside a Pen that will be connected to either Tab/Cellphone or Laptop via BLE. This system has builtin MIC and a Switch. When the switch is pressed and a word is said, it can be either directly written onto the screen or you can have a google search for it.

Design new PCB
I rehired Chirantan after successfully testing my first microcontroller project with him. Even after the project was closed, he continued to help me with installing the proper drivers and bootloaders. This time, I asked if he could design a more complex PCB and he provided me with a very good looking board. Very professionally and in a timely manner.
