TECNOIOT 5 pieces CJMCU-MCP4725 I2C DAC Module Development Board12 bit resolution
Description
- 【MCP4725】 MCP4725 I2C DAC Breakout Module Development Board CJMCU-MCP4725 【Design compact】 The 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. 【High performance】 12-bit resolution, I2C Interface (Standard, Fast, and High-Speed supported), Small package, 2.7V to 5.5V supply, Internal EEPROM to store settings 【Fast delivery】 Fast and high quality delivery of Spain buying in TECNOIOT ›See more product details

Very simple to use DAC module.
A stepper motor controller (for a dosage pump) I have here uses an analogue voltage instead of PWM for speed control. This has advantages, e.g. allowing the pump to be controlled experimentally with a pot and without a microcontroller (MCU). To control it from an MCU I needed a 0-5V DAC output, and this module turned out to be nice and small and easy to use via I2C. Example code is easily found online, but I read the MCP4725 data sheet and found it easier to use the "fast mode" supported by the device. I can't think of anything bad to say about this so I guess it's 5 stars!
