Digital potentiometer, 50KOhm, 8-bit resolution.

Form: M1S
  • 5V - Consumes 10mA
Mates with: #19, #20, #21


The Tibbit is based on the MCP4561 digital POT IC from Microchip. This IC has an 8-bit resolution. Refer to Microchip datasheet for operation details.


There is one red and one yellow LED. The red LED is connected to the SCL line of the I2C interface, the yellow LED — to the SDA line.
