This is ADS1115 16-Bit ADC – 4 Channel with Programmable Gain Amplifier. For micro-controllers without an analog-to-digital converter or when you want a higher-precision ADC, the ADS1115 provides 16-bit precision at 860 samples/second over I2C. The chip can be configured as 4 single-end 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 it’s super easy to use. It is a great general purpose 16-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 to one of four options (see the datasheet table 5) so you can have up to 4 ADS1115’s connect on a single 2-wire I2C bus for 16 single end inputs.
To get you start, we have example code for both the Raspberry Pi (in our Adafruit Pi Python library) and Arduino (in our ADS1X15 Arduino library repository) Simply connect GND to ground, VDD to your logic power supply, and SCL/SDA to your microcontroller’s I2C port and run the example code to start reading data.
Features of ADS1115 16-Bit I2C ADC 4-Channel Programmable Gain Amplifier Module:-

• WIDE SUPPLY RANGE: 2.0V to 5.5V
• PROGRAMMABLE DATA RATE: 8SPS to 860SPS

The Raspberry Pi Foundation has released a new version of its flagship model, the Raspberry Pi 4 Model B with 8 GB Ram. In addition to the models that come with 2GB and 4GB of RAM, there’s a new 8GB RAM model.

As always, you get a single-board computer that is the size of a deck of cards. It has an ARM-based CPU, many ports, Wi-Fi, Bluetooth and a big community of computer enthusiasts. You’ll be able to run applications that require more RAM, whether you use the Raspberry Pi to run a server or as a desktop computer.

All other hardware is the same as before except the RAM variation in this new Launch.

What else has changed?

To supply the slightly higher peak currents required by the new memory package, they have shuffled the power supply components on the board, removing a switch-mode power supply from the right-hand side of the board next to the USB 2.0 sockets and adding a new switcher next to the USB-C power connector. While this was a necessary change for this upgrade.

 

Key Features and Specifications of Raspberry Pi 4 Moedl B with 8GB RAM:

Faster processing:-

With one of latest Broadcom 2711; Quad-Core Cortex A72 (ARM V8-A)  64-bit SoC Clocked at  1.5GHz  processor improved power consumption; and thermals on the Pi 4+B means that the CPU on the BCM2837 SoC can now run at 1.5 GHz; a 20% increase on the previous Pi 3 model (which ran at 1.2GHz).

Video performance on Pi 4 B is upgraded with dual-display support at resolutions up to 4K via a pair of micro-HDMI ports; hardware video decode at up to 4Kp60 which supports H 265 Decode (4Kp60); H.264, and MPEG-4 decode (1080p60).

 

Faster wireless:-

A significant change on the Pi 4 B compared to the previous Pi 3 models is the inclusion of a new faster; dual-band wireless chip with 802.11 b/g/n/ac wireless LAN.

The dual-band 2.4GHz and 5GHz wireless LAN enables faster networking with less interference and the new PCB antenna technology allow better reception.

Latest 5.0 Bluetooth allows you to use a wireless keyboard/trackpad with more range than before without extra dongles; keeping things nice and tidy.

 

Enhanced Ethernet Connectivity:-

The Pi 4 B has significantly faster-wired networking with USB 3.0 technology; thanks to an upgraded USB/LAN chip; and you should see speeds that are 10x faster than on previous models of the Pi.

The GPIO header remains the same, with 40 pins; fully backwards-compatible with previous boards as on the previous three models of Pi. However; it should note that the new PoE header pins may contact components on the underside of some HATs; like Rainbow HAT. Some standoffs will prevent any mischief from occurring though!
