Design with Adafruit WICED Feather in Cirkit DesignerThe Adafruit WICED Feather is an innovative development board that integrates the robust Feather platform with the wireless capabilities of Broadcom's WICED (Wireless Internet Connectivity for Embedded Devices) platform. This board is designed for hobbyists, engineers, and makers who require Wi-Fi connectivity for their projects. It is ideal for Internet of Things (IoT) applications, wireless sensor networks, smart home devices, and other projects that demand internet connectivity and wireless communication.
This circuit consists of an Arduino UNO connected to an Adafruit OLED FeatherWing display via I2C communication (SDA and SCL lines). The Arduino is powered through a Vcc source and provides 3.3V and GND connections to the OLED display. The Arduino runs a program to display 'Hello, World!' on the OLED screen.

This circuit features an Adafruit HUZZAH32 ESP32 Feather board as the central microcontroller, which is connected to an Adafruit Quad AlphaNumeric Featherwing display and an Adafruit ADXL343 accelerometer via I2C communication (SCL and SDA lines). The ESP32 controls a vibration motor connected to one of its GPIO pins (A5_IO4) and shares a common power supply (3.3V) and ground (GND) with the other components. The purpose of this circuit is likely to read acceleration data, display information on the alphanumeric display, and provide haptic feedback through the vibration motor.

This circuit integrates an Adafruit MPR121 capacitive touch sensor with an Adafruit Feather 32u4 Bluefruit microcontroller. The MPR121 is powered by the 3.3V supply from the Feather and communicates with the microcontroller via I2C, with SCL connected to pin 3 and SDA connected to pin 2 of the Feather. This setup allows the Feather to detect touch inputs from the MPR121 for further processing or wireless communication.

To use the Adafruit WICED Feather in a circuit:
#include <Wire.h>
#include <SPI.h>
#include <WiFi.h>
// Your network SSID (name)
char ssid[] = "yourNetwork";
// Your network password
char pass[] = "secretPassword";
void setup() {
// Initialize serial communication
Serial.begin(9600);
// Check for the presence of the shield
if (WiFi.status() == WL_NO_SHIELD) {
Serial.println("WiFi shield not present");
// Don't continue if the shield is not present
while (true);
}
// Attempt to connect to WiFi network
while (WiFi.begin(ssid, pass) != WL_CONNECTED) {
Serial.print(".");
// Wait 10 seconds for connection
delay(10000);
}
Serial.println("Connected to WiFi");
printWiFiStatus();
}
void loop() {
// Main logic for your project would go here
}
void printWiFiStatus() {
// Print the SSID of the network you're attached to
Serial.print("SSID: ");
Serial.println(WiFi.SSID());
// Print your board's IP address
IPAddress ip = WiFi.localIP();
Serial.print("IP Address: ");
Serial.println(ip);
// Print the received signal strength
long rssi = WiFi.RSSI();
Serial.print("Signal strength (RSSI):");
Serial.print(rssi);
Serial.println(" dBm");
}
Q: Can I use the Adafruit WICED Feather with Arduino IDE? A: Yes, you can program the board using the Arduino IDE with the appropriate board package installed.
Q: What is the maximum voltage for the GPIO pins? A: The maximum voltage for the GPIO pins is 3.3V. Applying higher voltages can damage the board.
Q: How do I update the firmware on the Adafruit WICED Feather? A: Firmware updates can be done through the WICED SDK or via the bootloader using a USB connection.
Q: Can I power the board using both USB and battery at the same time? A: Yes, the board has a built-in charging circuit for the LiPo battery when powered via USB.
