[Update: I’ve finally received an answer: Lemon Pi and RoseapplePi makers are different companies, but they just happen to both use the same Actions Semi S500 reference design, and RoseapplePi is manufactured in Taiwan. The picture above is V1.0 board, but V1.1 will have some modifications]
Lemon Pi development board was launched this May via a Indiegogo campaign. The board, based Actions Semi S500 quad core Cortex A9 processor, got fully funded by over 200 backers, but at the time of launch, some people questioned the used of the word “Lemon” in a product name, as it has several pejorative meanings, including “something that is useless or crappy”. I was contacted about a new Roseapple Pi board yesterday, and upon checking out the details, it looks exactly like the Lemon Pi, except it got upgraded to 2GB RAM, just like in Indiegogo…
The board name on the PCB also reads Actions_S500_V1.0 on both boards, so although I have yet to receive a confirmation, that means Roseapple Pi is either the new name of the Lemon Pi, or Lemon Pi makers cooperated with Roseapple Pi, unless a company went copy & paste in a big way…

Supported operating systems include Debian, Ubuntu, Fedora, and Android 5.0/5.1. I’ve been informed source code and hardware files will be uploaded to xapp-le guthub account (there’s nothing there right now), and developers can get support via linux-xapple open source community (aka XApple) dedicated to Linux on Actions Semi processors and boards with Forums and a Wiki. XApple is said to stand for “Actions (represented by X) APplication Processors with Linux Embedded”.
There’s no price for Roseapple Pi board, but for reference Lemon Pi was $35 + shipping on Indiegogo, and it should be shipping soon since I’ve been asked to provide my address for a sample. A few more details can be found on Roseapple Pi website (Still work in progress).
