300 Intersil ‘Flower Power’ light-sensing reference design boards will be given away by distributor Future Electronics at Embedded World 2017 in Nuremberg ( March 14-16). The Flower Power reference design board will be demonstrated live at the show and celebrates the 50th anniversary of the San Francisco Summer of Love.
It has a five-petal flower outline and features five RGB LEDs on the front. Signals from an Intersil ambient light sensor are used to control the brightness of the LEDs. The flower board also features a Microchip ATmega328P picoPower 8-bit AVR microcontroller programmed to play five songs while the LED lights flash in random patterns.
In addition, the flower board is powered by two CR2032 Energiser coin cell batteries, displays a light pattern to alert the user when the batteries’ state of charge is low, automatically enters power-saving mode and includes a suction cup hanger.
The reference design includes the following Intersil parts:
* ISL85005 – 5A high efficiency synchronous buck regulator with a 4.5V-18V input
* ISL29102 – Low-power ambient light-to-voltage non-linear converter
* ISL21080 – 300nA NanoPower voltage reference
* ISL28915 – NanoPower push/pull output comparator It also includes an Abracon ASPI-0630LR power inductor and a Murata PKLCS1212E4001-R1 piezoelectric sounder.
Visitors to Embedded World should visit the Future Electronics stand 3.225 to enter the ‘Drone Pilot’ competition to win one of the 300 free Flower Power boards being given away over the three days of the show.
