Hello, I am a Senior Hardware developer.
I have been working as a embedded hardware designer for 10+ years.
I had developed several similar projects using the various microcontrollers such as STM32F1/2/3/4/7xx, PIC16/18xx, Wifi(ESP32, ESP8266), Zigbee, BLE/Bluetooth, Atmega, and the various Sensors.
I can review and find out the mistake in your current design. And help you from designing to produce the small production.
I have many experiences of schematic and multilayer(2~8 layer) PCB design with various BGA core(Cortex series, A series, FPGA ...), DDR3, DDR4, Ethernet,eMMC, HDI, WiFi.
I am sure I can complete it on time with high quality.
In that sense, I think I am the suitable persons you are looking for.
If you give me a chance to interview, I'll explain in more detail and I'll do my best for you.
I will work hard and hard to complete this task successfully.
Best regards.
