I'm an electrical engineer originating from The Faroe Islands, but currently living in Greenland where I've been headhunted and assigned the role as Project Manager for a telecom core swap. I'm very busy atm. and thus need help to finish of a private project which is causing me a lot of headache... The task is the following: Help me finish my PCB design and make it work. I've already made three iterations of the PCB and have failed. My breadboard design is working (using modules), so it should be possible. Minimum criteria: Size: 52mm x 40mm Fitting: There must be two small holes for fitting in enclosure DRU Files: Eagle dru files for Eurocircuits Main components: ESP-WROOM-32, ADXL345, SIM800C (+ antenna, SIM card holder, etc), QI charger (MCP73831), MTK MT3339 (FGPMMOPA6H), WS2812B, 3 SPST + whatever else is needed of RLC components to get this thing to work. Battery: shall use 3,7V 1500mAh battery (model 504050) Preferable criteria: Use my Eagle CAD files and hand them back to me when you are finished (alternatively use whatever CAD you prefer) Optional criteria: Help me find another PCBA than Eurocircuit - which also is faster Add a small microphone to the design Add a small PCB GSM antenna to the design Add small USB programming interface to the PCB I'm having major issues with the SIM800C and SIM attach, network attach, etc. It just never works. This implies, that I'm having some power issues. I've also seen some strange behaviour from the ADXL345 and now also from the GPS (?!). I thus suspect, that I'm making some errors with the signal traces (inducing some parasitic trace capacitance) when using the autorouter. But I'm completely lost now and have no idea what to do...

You need help to correct your current design and support to make working prototype. So we will start with revising your schematic to see power supply design, necessary capacitors, appropriate voltage translation for such mix of different working voltage modules. Then replacement components and route manual. Automatically routing almost never work for such kind of design. And finally, support you to make prototype of course. No up-front payment, always pay after receive works. Just short introduce: i have developed devices for IoT using GPS, GSM, BLE modules so having experiments with such system. Can discuss more to show. And if you want, can suggest you to use better modules also.

Hello My name is Amr , I have been working in the field of electronic products design , prototyping & Manufacturing for more than 8 years , i also have very good experience with mass production and manufacturing in general plus having multiple trusted PCB & PCBA Factories that i tested personally and visited over the years , also i can provide a full supply chain of all items included with high quality and competitive prices I can provide the following services 1- Electronic Products Design Consultation 2- Up to date components selection achieving high efficiency & availability 3- Schematic , Layout and Gerber files 4- BOM , and full supply chain for all related parts ( Batteries , LCDs , Solar Panels , Antenna , connectors , wires ....... etc) 5- Prototyping & Mass Production remote Management with factories & suppliers Note Design Program for both Schematic & Layout : Proteus I have few notes for you as an advice to consider 1- Keep the antenna out of the PCB , use buy an external one starting from 1-2$ or increase the board size as this is too small to add micro strip antenna 2- the SIM card holder has to be as close as possible to its pins at the SIM800 Module also make sure to add ESD protection not to damage your chip 3- You need to use at least 4 layers PCB for this to work 4- 1500mAh battery is too small for this system , at least 3000mAh battery other wise you will keep having power issues feel free to contact me any time

Hello, I have been making embedded electronics products since 5 years. I have worked on C, C++, python, etc.. on Microchip, Atmel, ST micrcocontrollers. I have also made approx 100 projects on Raspberry pi, Beagle bone, etc.. ARM boards. I have worked on SIM800C for a lot of projects. It is a bit tricky. The GSM pad should be UFL and there are some other parameters to take care of. I have done projects like building automation, home automation, industrial automation, touch switches, security systems, analog designed SMPS, wireless networks, IOT based solutions, RFID based solutions, NFC based solutions, etc.. Share your project details so we can discuss further

Hello Sir, Hope you and your family is doing good. I am Asmat Ali from India. I Have 3+ Year of experience in hardware Design Feild having experience in schematic and PCB Design with mass manufacturing also in 3D Design.I have started my freelancer account recently so as this is my first project I keep my price low. I have designed previously a gsm fully working board on SIM808 module and with an accelerometer adxl345. Used in Car security purposes.I have designed with Altium designer also having expertise design esp32 with module and with coustom board.I have also designed charger circuit for lipo batteries and dc dc convert.. that could be best for your application.. As per your project having GSM module and accelerometer and RGB Led and chargers, And supporting components.. I recommend you to not place a pcb antenna on board because this will increase complexity of matching circuit. always use external antenna also you need to manufacture board with 50 ohms impedance trace to work gsm. Let me know what problems you faced during your proto board.I will make board accordingly.I will provide you fully working design with schematic.. Looking forward to hearing from you... Thanks.
