These arrived in the post today. The first is a Strobon module for “Aircraft Avoidance” and needs to be mounted to a controller and power supply. The second is a self contained unit with a Flytron strobe, controller and tiny LiPo power supply. The power supply is recharged via a micro USB socket on the board.
They are TINY!
In a typical, “Laurel and Hardy” moment, my Son and I were marveling at the Flytron assembly when I (stupid old fart) accidentally turned it on and both of us are now waiting for the dark shadow to disappear from our eyesight 
Dumb, very dumb.
