LM3909 Discrete Component Module

A recreation by Shaun Jones of the long-obsolete LM3909 LED flasher/oscillator.
Originally released in 1975 this popular IC featured a charge pump, allowing the user to power a 2V (Vf) LED from a 1.5v battery. It has low power consumption and works well at 5Vdc.
The board follows the same pin-out as the original and is breadboard-friendly - pin headers are provided for you to fit.
Follow the link to the original IC datasheet (see below) for more details and example circuits.
