Hello,
I'm very interested in working with you. Please would you share with me more information about the sensor you are using? Do you have any special requirements about the PCB? I have experience in BOM research, electronic circuit design, PCB design, manufacturing order and firmware development in projects similar to the one you want to do in this proposal. Once I know more about the sensor you want to use we could better define the project deliverables, delivery time, and budget.
I have a university degree in Electronic Technology, I specialize in PCB design at KiCAD and in embedded system development with more than 3 years of experience. As you can see in my portfolio (https://www.freelancer.com/u/Jainojosa?w=f), I have successfully participated in the design of the electronic circuit, PCB design and firmware development for applications in: medical devices, digital signal derivation, IoT devices, power supplies and 12V@3A power distribution. I specifically highlight my experience working with:
• Communication protocols: UART, I2C, SPI, MQTT.
• USB-UART converters (CP2102N-A01-GQFN28).
• WiFi and BLE modules (ESP8266, ESP32).
• Microcontrollers (Arduino, Tiva TM4C123, Tiva TM4C1294, Teensy 3.2, Raspberry Pi).
• Sensors (LM35, DHT11, PIR HC-SR501, ACS711KEXLT-15AB-T, etc...)
I look forward to working with you.
Best regards,
Javier Inojosa.
