ISD1700 Series Voice Record Play ISD1760 Module For Arduino PIC AVR Description: 1. ISD1700 voice module description ISD1700 voice module is quickly become familiar with and master the ISD1700 series chips designed for a simple and practical circuit board. It applies to all ISD1700 series chip, with a simple, fully functional characteristics. Recording chip ISD1700 series is a highly integrated, high-performance chips. It can be multi-segment recording, sampling rate can be adjusted from 4K to 12K, the power supply can range from 2.4V to 5.5V. ISD1700 there was the new recording prompts, when a new recording after, LED back flash once every few seconds to alert users to new recordings. In addition there are four kinds of sound to prompt the user's operating results, such as start recording, stop recording, erase, erase all the next one and so on. Recording data is stored in the FLASH chip, without any compression, so there is a better sound quality and power storage. Chip has two independent audio signal input channel, microphone input and analog signal inputs. In independent key mode, when the operation is completed, a functional chip will automatically enter power-down mode to reduce power consumption. In SPI mode, the user can do more functions on the chip operation.

HiLetgo ADS1115 16 Bit 16 Byte 4 Channel I2C IIC Analog-to-Digital ADC PGA Converter with Programmable Gain Amplifier High precision ADC Converter Development Board for Arduino Raspberry Pi
- Description: For microcontrollers without an analog-to-digital converter or when you want a higher-precision ADC, the ADS1115 provides 16-bit precision at 3300 samples/second 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. 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. 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. Parameters: ADC Bit rate: 16 Bit Interface Type: I2C Channels: 4 Channel AN0 AN1 AN2 AN3 Input voltage: 2.0 v- 5.5 v Channel input voltage: 0-VDD Continuous Mode: Only 150µA Single-Shot Mode: Auto Shut Down Programmable data rate: 8sps-860sps Input range programmed control, 7 types input ranges: - 0.256V ~ + 0.256V, - 0.512V ~ + 0.512V, - 1.024V ~ + 1.024V, - 2.048V ~ + 2.048V, - 4.096V ~ + 4.096 V, - 6.144V ~ + 6.144V I2C 7-bit addresses between 0x48-0x4B Package Included: 1* ADS1115 16 Bit 4 Channel Analog-to-Digital ADC Converter 1* Pin Header
HiLetgo Stackable SD Card TF Card Micro SD Card SD/SDHC/Micro SD/Micro SDHC Card Reader Shield Multi-Functional SD Card Shield Module for Arduino UNO R3 MEGA2560
This SD card shield is a standard SD card / TF card break out board for Arduino. The SD card shield adds storage to your Arduino project.Stackable SD Card Shield is a stackable design SD / TF card expansion board. It supports direct insertion in the Arduino board to extend SD / TF read and write functions.SD / TF card expansion board uses the hardware ISP interface, so only supports SIP mode SD / TF card.This expansion board uses only a handful of pins, so the stack design allows you to plug in another expansion board on this board, provided that the same SPI pins are not used, such as Bluetooth expansion board, GPRS expansion board.Many electronic enthusiasts have provided a simple documentation program for Arduino. And we provide a simple TinyFAT file system library, you can easily achieve control SD / TF card reader - this library only supports FAT16 small capacity card, such as 1G card, if you need to support FAT32, you can use Official library for Arduino.
