Best Wireless I2c Arduino

Adafruit Power Relay FeatherWing [ADA3191]

High speed SPI display with digital I2C touchscreen driver.
Single-touch capacitive touch bonded on top.
240x320 resolution, 18-bit GPU, 262, 000 color - our library uses 16 bit color mode. Ili9341 (data sheet) controller with built in video ram buffer.
We also have a touch screen library that detects x, Y and Z (pressure) and example Code to demonstrate all of it. The Code is written for arduino but can be easily ported to your favorite controller.
Works with any classic arduino '328. Solder closed three jumpers to use the icsp header for use with leonardo or Mega! 2.8" diagonal color touchscreen TFT.
Touchscreen controller requires I2C pins sda and Sca. Microsd pin requires digital #4.
That means you can use digital pins 2, 3, 5, 6, 7, 8 and analog 0-5. Pin 4 is available If not using the MicroSD.

Digital sensor for measuring changes in VOCs, in particular Carbon Dioxide (CO2).
Simply supply power, connect WAK to Ground, and connect the SDA and SCL pins to the I2C pins on your Arduino, ESP8266, Raspberry Pi, etc..
Operating voltage of 3~5VDC. 2C address 0x5A.
Easy to use on a breadboard with the included 8-pin header.
CCS811 Carbon Monoxide (CO) Breakout Board for Arduino Raspberry Pi ESP8266 I2C 3~5VDC CJMCU-811 CCS801.

The TCA9548A adapter is connected to an I2C device with multiple identical addresses on the same I2C port on the main control board for normal communication and use.There are 8 I2C interfaces on one expander, and there are eight bidirectional transfer switches that can be controlled by I2C bus. This means that after 1 expander is transferred, 8 identical addresses can be connected to the same I2C port..
Expansion board TCA9548A compatible with IIC bus and system management bus (SMBus), active low reset input, support for hot insertion, low standby current, no glitch during power-up, support for voltages between 1.8V, 2.5V, 3.3V and 5V buses Level shifting, TCA9548A I2C IIC multiplexer breakout board depending on the contents of the programmable control registers, any single SCn/SDn channel or combination of channels can be selected..

The MCP4725 is an I2C controlled Digital-to-Analog converter (DAC)..
A DAC allows you to send analog signal, such as a sine wave, from a digital source, such as the I2C interface on the Arduino microcontroller..
On board are SCL, SDA, VCC, and another GND for your basic I2C pinout..
If you are looking to have more than one MCP4725 on a bus, the pull-up resistors on this board can be disabled just check the Hookup Guide in the Documents section below for instructions and tips on doing this.store settings.
Digital to analog converters are greInternal EEPROM to store settingsat for sound generation, musical instruments, and many other creative projects!.
