Electrical & Electronics Engineers

Hi , I have read and understood your requirements. I have strong expertise and technical knowledge in Engineering field. Please open chat window to discuss further to align the things.

1 ) I have over 20 years of experience in PCB Layout, HW, RF, EMI, FW designs. we can complete various design and layout requirements and Android / iOS app development # 8051 MCU / ARM Embedded system / Arduino / STM32 / IM6x / AVR / TI MSP430x / PIC # WIFI / BT / BLE / GPS # LCD / DTV / MD / Web Camera # LED / Lighting # RPIx / CM4 / CM3 / UP CORE PLUS # LCD Inverter / Touch sensor # NIC / LAN / KSZ9031RNX / LAN8720 # IOT / nRFF528x / ESP8266 / TI CC26x # Battery / Solar Charger # BMS ( Battery Management System ) # Audio / CSR / Codec / AMP / IO-Link / LTE EC25 / BG95 2 ) I can use as below to design and layout # Altium # Protel99SE # Eagle # PADS # KiCad # OrCad # Allegro # Proteus # DipTrace 3 ) I can communicate well in English, please contact us by e-mail or s-k-y-p-e me (saludpcb) to find out relevant details. 4 ) I also have to provide PCB layout design service (super low price) # For PCB layout: 2 ~ 4 Layers -> $0.4 ~ 0.6 USD per pad @ 6 ~ up Layers -> $0.8 ~ 0.8up USD per pad. # For reprinting of schematic and component, quotation will vary by each case. # A minimal of $100 USD 2L / $200 USD 4L / $300 USD 6L will be charged for each case. # 1 ~ 8up layers ( PCB / FPCB ) High Speed / High Density PCB layout # Differential Signal PCB layout # RF Signal PCB layout # 3D Models # FreeCad 5 ) PCB / PCBA (EMS) # Prototype assembly # Components procurement # Assembly # High quality # Quick, 24hr lead time # Low cost

Hello! Can you please share what microcontroller do you want to use? STM32 is a very big family and controllers differs significantly. And one more, can you say what source of boot do you want to use? Flash? Some serial interface? If you share details, I will be able to help you woth the project.

Hi iam a professional electrical engineer , i have grip on microcontrollers and its coding and can be implemented using Proteus software and mplab for coding . i think i can do good work for u.

hi , im an electrical engineer , im famous with microcontrollers , i can help with tgis project and we can discuss about it

Hi, We have 6+ years of experience in embedded software field. I have good experience in bootloader customization & Boot-Flow designs. Experience in Bootloader: 1. Application binary programming into flash from bootloader (To detect UART or USB device) 2. Application software integrity checking & boot cycle's(CRC32 checking) 3. Secure booting(Application software encrypted by AES with unique keys(chip specific encryption) 4. Memory Layout design with respect to application binary size & available memory 5. Dual application booting mechanisms(A/B Booting mechanism) 6. Version maintenance ( In platform like same version software not download, only allow higher/lower version sw) 7. Signal/Power Integrity analysis, Thermal Analysis 8. Schematic Capture,High speed PCB Design Experience in chipset: 1. STM32F207,STM32RCT6 2. PIC32MZ2048 3. ESP32 with MQTT (Attendance system) Looking forward...
