Hi, I have more than 10 years of experience in embedded design and development. I have expertise in PCB design up to six layers using different CAD tools like Altium designer, Cadsoft Eagle, Kicad etc. I also have great experience in firmware development on different platforms. I have hands on experience in - Component selection - Components library design - Schematic design - PCB layout design - Gerber and BOM generation - Manufacturing files generation (pick n place, assembly, DWG, step etc.) - Protocols (SPI,I2C,UART,CAN,TCP/IP) - Sensors integration (Acclerometer,Gyroscope,Inclinometer,Temperature,Humidity,Pressure,Heart rate, Load Cell, Ultrasonic etc.) - Batteries optimization(LiPO,LiIon,Alkaline,AA,AAA,18650) - Power supplies (LDO, Switching regulator, Buck-boost converter, battery charging, PMU) - Motors control(servo, stepper) - Displays interfacing (LCD, OLED) - Wireless modules interfacing(Wi-Fi, BLE, RF, Cellular, GPS, Lora, ZigBee) - MCUs/MPUs with external RAM,ROM - External memory interfacing (NOR/NAND FLASH, SD Card, EEPROM etc.) - IoT expertise with Cloud integration I have recently worked on speaker related application using nRF52840 and MAX98357A boards. I tested MAX98357A module with ESP32-WROOM dev board to verify it's working and then developed firmware for nRF52840. I have MAX98357A board, 2 Ohm speaker and also ESP32 with me. let's have discussion. Thanks. Jitendra
