Getting started with the Azure Sphere Starter Kit! If you are an Element14 road tester like us, you're in for some cool info. Here we wanted to make a simple blog informing makers, hobbyist,  engineers & etc on how to get going with the hardware.

This board can be broken down into a few sections for clarity. Since there are an overwhelming amount of bells and whistles, we'll just list some features we like.

  • USB to serial 4-port interface (FT4232HQ) o Debug, Service, Recovery and SWD
    interfaces(This explains the three (3) COM ports you see in your Device Manager
  • Onboard sensors: o Ambient Light, 3-axis Accelerometer, 3-axis Gyro, Temperature,
    Barometric Pressure
  • Multiple hardware expansion interfaces: o MikroE Click Board Expansion Sockets (two
    sockets. I2C,SPI,UART,ADC,etc interfaces)
  1. UART/BLE connector (2x6 pin R/A connector, compatible with a subset of Pmod boards)
  2. Grove expansion connector (I2C)
  3. Interface for optional OLED 128x64 display (I2C)
  4. Battery backup interface (2-pin VBAT compact terminal, not fitted)
  5. +5V DC Aux interface (2-pin compact terminal, not fitted) -
  • Push-button switches (3) and Status LEDs (7) -
  • 5V to 3.3V DC power regulation (with over/under voltage protection) and power interfaces
    for: USB 5V DC from host computer
  1. AUX 5V DC (option to fit compact terminals) 
  2. VBAT (option to fit compact terminals)
  3. ADC VREF external reference input (2-pin header) 

​Chip-Antenna Version Azure Sphere Module

  1. Chip-Antenna Version Azure Sphere Module
  2. 3x ISU interfaces, pre-configured for UART, SPI, I2C (max interface rates are: UART=3Mbps,
    SPI=40MHz, I2C=1MHz)
  3. ADC/GPIO: 3x 12bit ADC inputs (or can be used as GPIOs)  
  4. PWM/GPIO: 9x PWM outputs, or can be used as GPIOs (for a total of up to 24 GPIOs) 
  5. RTC : On-chip, requires VBAT supply 
  6. Antennas: U.FL connectors for external 2.4/5GHz flex antennas

​Beyond the readily accessible onboard sensors (Ambient Light, 3D Accelerometer, 3D Gyro, Temperature, Barometric Pressure), a key differentiating feature of this Azure Sphere Starter Kit is the availability of multiple hardware expansion interfaces:

  • MikroE Click Board expansion sockets (two sockets, I2C,SPI,UART,ADC,etc interfaces)
  • UART/BLE connector (2x6 pin r/a connector compatible with some Pmod boards, not fitted) 
  • Grove Expansion Connector (I2C)
  • OLED Interface for optional 128x64 display (I2C, not fitted)
  • VBAT battery connector (option not fitted)
  • AUX 5V DC (option not fitted)
  • ADC VREF external reference input
