CJMCU-I2C DAC Breakout - MCP4725 module development boardThe MCP4725 is a 12-channel buffered voltage output DAC with non-volatile memory (EEPROM) of. The user can configure the register bit (2) and DAC input data (12) stored in nonvolatile EEPROM (14-bit) memory. By setting the configuration register bits DAC can be configured as a normal mode or power-saving shutdown mode. The device uses a two-wire I2C-compatible serial interface, and a voltage range of 2.7V to 5.5V single supply.Description: You've 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 interf...
2PCS/LOT Standard Voltage Sensor ModuleSize: 25mm×13mm/0.98"×0.51"(approx)   This module is based on principle of resistive voltage divider design,   can make the red terminal connector input voltage to 5 times smaller.Arduino analog input voltages up to 5 v,   the voltage detection module input voltage not greater than 5Vx5=25V   (if using 3.3V systems, input voltage not greater than 3.3Vx5=16.5V).   Arduino AVR chips have 10-bit AD, so this module simulates a resolution of 0.00489V (5V/1023),   so the minimum voltage of input voltage detection module is 0.00489Vx5=0.02445V.   Voltage input range : DC0-25 V   Voltage detection range : DC0.02445 V-25 V...
