Example of Connecting 86Duino with Adafruit CC3000 WiFi shield
Adafruit CC3000 WiFi shield communicates with MCU board by SPI interface. It has two function pins: communicate and control. The communicate function pins are MOSI、MISO、CLK and can be connected to SPIDO、SPIDI、SPICLK on 86Duino SPI port; The control function pins are IRQ、CS、VBAT_EN and can be connected to 86Duino digital pin 42、43、44(default). In addition, Adafruit CC3000 WiFi shield also needs 5V and GND, we connect them to 5V pin、GND pin on 86Duino in sequence.
After you get the Adafruit CC3000 WiFi shield, need to solder eath header pins by refer to Adafruit CC3000 Shield Assembly Tutorial:
Then connect Adafruit CC3000 WiFi module with 86Duino, and we use 86Duino Zero for example here, show connected method as below:
Example for connecting：
Note: digital pin 43、SPICLK、SPIDI pins are very closed with the metal shell of 86Duino. To avoid shorted together, you should do some protect to isolate with the metal shell of 86Duino like below:
