Bees which do not have ATMega328 like Bluetooth Bee can only be configured by using on-board FT232RL(USB to UART)

It operates smoothly over the 3-12V range

Fermion: MCP42100 Dual Digital Potentiometer - 100K (Breakout) Shipping:1 day it is supported by thousandsDigital potentiometer is also called "Digital Pot" in short. It is a kind of mixed signal IC, which is able to dynamically change the internal resistors through MCU like Arduino. It can be applied to applications such as LED DC dimming, linear stable voltage source, oscillator, low pass filter or differential amplifier. This breakout employs MCP42100 internally manufactured with two individual 100K digital pots. It features as small size and low power
