Circuit design

Hi, For combination circuit like this, We need one more module, which is Microcontroller. I think STM32F407 is best for this combination module. because it has SD interface for SD card,6 UART (usually for GPRS and Bluetooth), camera interface, and lot of I/O. For Charger module, we can use Texas Instruments charger module. But if budget / dimensions are limited, we can use ESP32 as Bluetooth and main microcontroller. I have use STM32 since 2012 and has done lot of project on it. I have became pcb designer since 2012 and has done lot of project from Hobbyst, Robotic, Industrial, IoT, and Military application. I have experience designing similar project like this one several times. And I know it's popular issue, including power issue, antenna issue, grounding, etc. I will use Eagle, and 2 layer is enough for this project. let's discuss the detail over messenger. let me help you realize this project. Best Regards, Rijal

I have interfaced Gprs, GPS , Bluetooth, wifi module, camera, SD card with Arduino in one circuit used for Attendance system, access control system, personal device locator, and lots more Relevant Skills and Experience Core skills of embedded C/C++ is required. Knowledge of circuit design and multiplexing is needed. Serial communication skill is needed.

If you have schematic ready and only want PCB layout than i will finish it in 15-20 days regardless of any emergency and if whole designing is to be done than it would charge more

Have experience with design schematic and pcb. It will be done in Altium.
