Haiyan Z.

I am an Automation system design engineer, Hardware designer, Firmware developer and have the extensive experiences even over 15 years. I'm especially interested in home automation or making intelligent new products or acquire and application new technologies. I work with the target of design to low cost, low power, high performance, the miniaturization of device by a compact layout. I design carefully to achieve the best performance in all projects, I find joy and pride in the successful results of projects. The areas I've experienced a lot are as follows. ● STM32F103RCT6TR, STM32F407VGT6, STM32F429ZIT6, STM32L476RGT6, STM32H743ZIT6, etc. ● ESP32-WROOM-32D, ESP32-WROVER-E, ESP8266, etc. ● nRF51822, nRF52810, nRF52832, nRF52833, nRF52840, nRF52843, etc. ● RAK811, RAK831, RAK3172, RAK4200, etc. ● SIM7000G, SIM7070G, SIM7600E, SIM7600G, etc. ● Arduino Mega2560, Arduino Mega328P, etc. ● SRAM, DDR, DDR2, DDR3, LPDDR3, DDR4, DDR5, LPDDR4, etc. ● MEMS Sensors (3-axis, 6-axis, 9-axis), ECG, PPG, HRM, SPO2, CO, CO2, Humidity and Temperature, Touch, Pressure, PIR, etc. ● PCIe, SATA, Ethernet, HDMI, VGA, LVDS, USB, UART, USART, CAN, SPI, I2C, I2S, RS232C, RS485/RS422, etc. ● BLE, IoT, AWS, GPS, GSM, Bluetooth, Wi-Fi, Z-Wave, Zigbee, LoRa, NFC, RFID, LTE, etc.
