Professional Hardware Engineer

Hello! My name is Manh, professional hardware engineer My job is design hardware circuit, test circuit, program for electronic product and program software on PC to manage/communicate with circuit boards. Just give me your requirements/product specification. Then we can discuss about the deadline, price and other features. I have more than 7 years experience in design hardware for IoT Products, Consumer Products and Telecom Products. So I think i can try my best to complete your project with best result Below is my work flow in hardware design: - Receive your requirements, discuss to have final product/circuit specs - Design block diagram for circuit: need to very detail, it will decide what part will be used in project - Design schematics: follow block diagram to design schematic for product - Design PCB Layout: with requirement about Mechanical Design and Industrial Design, i will do the PCB Layout the fit with your MD that archive best performance - Extract production data: BOM, CAD, GERBER, DESIGN, ASSEMBLY GUIDELINE, IMPEDANCE CONTROL REQUIREMENTS, ... Something about my experience: - About microcontroller: STM32F0/F1/F2/F4/F7, MSP430, MSP432, ATMEGA, ATSAM, PIC, ... - About SoC and MPU: RK3399, Allwinner A10, RTS3902L/RTS3902, RTL8188/8192, ... - About dev board: Arduino, RPi, Teensy, ... - About Wireless MCU: ESP8266, ESP32, CC2530, CC2538, DA14580/14583, CC2540/41, nRF51822/nRF52840, CC1310, ... - About Sensor: CMOS Image Sensor, light sensor, CO, Smoke Sensor, Dust Sensor, Air Sensor, pH sensor, .... - About wireless communication: WiFi, BLE4.0/4.1/4.0, Lora, Zigbee, Sub1GHz, ... - About GPRS/3G/LTE Module: SIM800C/H, SIM900A, SIM908, SIM5320, SIM5360, Quectel MC60/M95/UC15/UC20/EC20, Sierra HL8548, SIM7600E. - About highspeed PCB Design: DDR3/DDR4, SATA, HDMI, USB2.0/3.0/TypeC, eMMC, ... - About Mass Production: I can help you prepare production data that help you do the mass production. I also have experience in mass production process for IP Camera and Home Gateway with very big quantity, so i will know how to design for manufacturing with your product, design mass production process, etc Some of my product that I have designed and released to the market: - Home IP Camera: using SoC with DDR3-RAM, livestream via Ethernet and WiFi, have light sensor, IR-Led Array, IR Cut control, CMOS Image Sensor, Flash, USB and MicroSD Card - Smart Home Product: Design Home Gateway with Ethernet, WiFi, Zigbee and TFT LCD, ...
