There is a DAC chip module based on Microchip MCP4725 chip. All WebControl WC8 and WC32 boards can use that chip to send out analog output. Its output has 12bit resolution to provide voltage reference. Through a RC filter and comparator IC to drive external analog devices. It can be purchased from eBay or some other web site

The board has address select pin A0 soldered to ground, so that default I2C address is 0xC0 for write, and 0xC1 for read. This MCP4725 also has an EEPROM register, so that if a value stored in it, its output will be set to the stored value when power up, without even program it.
Does anyone interested in this chip?
