This easy to use led driver board is designed and set up for running External Led indicators from your HKPilot Mega or APM. You can easily control 12V led’s up to 700ma from the A4~7 pins on your APM compliant Flight controller. 12V external high visibility LED Indicators for Motor arms, Arm status, GPS, and Low voltage can now easily be controlled with this must have flight controller accessory.
Input voltage: up to 12V
Channels of LEDs: 4
*Note: The reference to APM refers to the ArduPilot project, a family of open source autopilots based on the Arduino open source computing platform, developed by 3DR and the open source community. It consists of a choice of ArduPilot Mega (APM) electronics and a range of free software versions for different vehicles and is governed by an open source creative commons license.

Easy to setup and does exactly what it is suppose to.Great little board. Built flame wheel quad with HK Pilot Mega. Used four green / red LED strips for the arms. Connected the driver board input connection to the pilot mega inputs. Connected the very small power wires to the power distribution board. Great light display whin the quad is powered up.using this in combination with strip lights makes it easier to know whats happening. im using it for Arming, GPS might add a 12v buzzer as wellUsed with 4x 3-LED long RGB-strips, one Red, one Green, one Blue and one White. Works great, and apparently on lower voltages too (~9 V) if you prefer dimmer LEDs, feeding with 3S should work, maybe even 2S if you'd need it? Hardware information: The chip is a Texas Instruments ULN2003A Darlington transistor array, datasheet can be found by searching for "uln2003a.pdf", seems like it has the capability to drive up to seven loads.
Downsides: The 12V input wires seem a bit flimsy for 700mA.Great board. It came without instructions,but I soldered some test leds and figured out outputs.I use it on my s500 quadcopter - apm 2.5.2 from HK. Led strip(6x smd led) on each arm of frame. Just set parameter "LED_MODE" to 107(default is 9). I have gps lock blue led. When battery voltage is low red leds are flashing. Firmwavre is AC 3.2 rc7.No instructions came with mine. The video is too general to be useful. Please supply a wiring layout or smple setup so that people can use these.
