（pack of 6 ）This D1 mini module is a mini WIFI board based on ESP-8266EX..
Our D1 mini development board is 100% compatible with Arduino WeMos and can be programmed in Compatible with Arduino IDE..
Support OTA on line.Compatible withArduino compatibility. Using Compatible with Arduino IDE for programming..
This WLAN board contains 11 digital input / output pins, all pins have interrupt / pwm / I2C / 1-wire and a micro-USB connection..
11 digital input / output pins, all pins with interrupt / PWM / I2C / support 1 line (except D0).
1 analog input(3.2V max input). Micro USB connection.

The TCA9548A Breakout board supports communicating with multiple I2C devices with the same address, making it easy to interface with them..
TCA9548A multiplexer features: bidirectional eight-channel I2C multiplexer, active low reset input.
The default address of this expander is 0x70, the address can be changed, and can be set within 0x70~0x77..
In the address of 0x70~0x77, 8 expanders can be cascaded, and each expander can be connected to 8 devices with the same address, so that the same I2C port can be connected to 64 devices with the same address and can be used normally..
The chip is compatible with 3V and 5V and can be used with any logic level.

For microcontrollers without an analog-to-digital converter or when you want a higher-precision ADC, the ADS1015 provides 12-bit precision at 3300 samples..
Cond over I2C,The chip can be configured as 4 single-ended input channels, or two differential channels..
As a nice bonus, it even includes a programmable gain amplifier, up to x16, to help boost up smaller single/differential signals to the full range..
We like this ADC because it can run from 2V to 5V power/logic, can measure a large range of signals and its super easy to use. It is a great general purpose 12 bit converter..
The chip's fairly small so it comes on a breakout board with ferrites to keep the AVDD and AGND quiet. Interfacing is done via I2C. The address can be changed , you can have up to 4 ADS1015's connected on a single 2-wire I2C bus for 16 single ended inputs..
