5Pcs CJMCU-MCP4725 I2C DAC Breakout Development Board Module   Description:    Youve always wanted to output analog voltages from a microcontroller, the MCP4725 is the DAC that will let you do it! The CJMCU-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. Digital to analog converters are great for sound generation, musical instruments, and many other creative projects!   This version of the CJMCU-MCP4725 Breakout fixes a few issues with the board including the IC footprint, the I2C pinout, changes the overall board dimensions to better fit your projects, and a few more minor tweaks. This board breaks out each pin you will need to access and use the MCP4725 including GND and Signal OUT pins for connecting to an oscilloscope or any other device you need to hook up to the board. Also on board are SCL, SDA, VCC, and another GND for your basic I2C pinout. Additionally, 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.   Feature:   12-bit resolution I2C Interface (Standard, Fast, and High-Speed supported) Small package 2.7V to 5.5V supply Internal EEPROM to store settings   Package included:   5 x CJMCU-MCP4725 I2C DAC Breakout Development Board Module

Feature: - Small size, complete function - Support to upgrade, support STM8 (SWIM interface), STM32 (SWD interface) full range of MCU - Dual channel power supply output: 3.3/5V - Onboard 500mA self recovery fuse, output series connected diodes to provide short circuit protection - With 4PIN connection cable Support the development environment and software tools: STM8: - STVD V4.2 or later version - STVD V3.2 or later version - IAR-EWSTM8 V1.3 or later version STM32: - KEIL MDK V4.2 or later version - IAR-EWARM V6.2 or later version - Atollic TrueStudio V2.1 or later version Package included: 5 x Programmer
