i have rich experience in design and development
of GSM/GPRS based system as well WIFI/
BLUETOOTH systems...
i can develop end to end product using SIM800C,
SIM800A, SIM900, SIM7600, ESP8266, ESP12,
ESP32, HC05, HC06 with supportive power
supply design using XL6009, LM2576 ADJ, LM317
etc. with also supportive MCUS like AVR, PIC
ARDUINO, RASPBERRY PI, MEGAWIN, NUVVOTON,
SILAB, TEXAS INSTRUMENTS, ANALOG DEVICES,
CYPRESS, NATIONAL SEMICONDUCTORS, ST etc.
i have rich experience in circuit design and
development with single layer as well as two layer
PCBs, student projects for final year electronics or
electrical engineering.
i have also developed so many industrial products
regarding stepper driver, servo drives, PLC,
SCADA, HMI, AC DRIVES etc
i can also design fully industry standard modules
with noise reduction and protocol subjected
devices for MODBUS, RS232, 12C, SPI, ADC, DAC
4-20mA, 0-10v systems...
hope you will find me right person and let's
discuss further to fulfill your requirements...
