This board features an MCP4661T, which is a 100 kΩ (±20%), 8-bit/257 step, Dual-Circuit Digital Potentiometer. The board operating voltage is 2.7v-5.5v, and features pin headers for I2C, ground, power, and analog terminals. Each Circuit (0 & 1) contains A and B terminals, which are non-polar, and W (acts as access, wiper point). This board can act as a programmable resistor, between A/B terminals & W (access). This board can also act as a programmable voltage divider, using the terminals as a voltage range, and W (access) as the voltage output. This board features an LED for power, a 10uF ceramic and 100nF ceramic capacitors, along with 4.7k pull up resistors for SCL and SDA. (All address pins are tied to ground). This MCP4661T breakout board will streamline your analog boards & give you effortless debugging.

Why did we build it?! We are tired of cheap breakout boards with no documentation that use off-brand chips. We think you should have an affordable way to get quality boards, with hand-written documentation, which is designed with the consumer in mind. We want to teach about electronics and give all hobbyist the tools to build great things. There's one word to describe this digital potentiometer board: Quality. We hope you enjoy it. Happy building!
