The Lemon Pi is a very low-cost open source single-board computer (SBC)
equipped with a powerful ARM quad-core Cortex A9 microprocessor integrated
with an Imagination PowerVR SGX544 GPU.There are a lot of the same
characteristics between Lemon Pi and Raspberry Pi 2，such as the price,the
size and the compatible 40 pin interface and so on.But the Lemon Pi has
more powerful computing and Imagination GPU hardware acceleration
capacity,more IO interface expansion etc.More importantly, Lemon Pi
supports many specifictions that Raspberry Pi 2 does not support, such as
USB3.0 host, OpenCL that Imagination PowerVR SGX544 supports, android 5.0.
S500, which is one of Actions Semi open cource chipset series called
ActDuino, is adopted on the Lemon Pi.
The specification is as following.
Operating systemUbuntu 12.04 + OpenGL ES/OpenCL/GPU acceleration on Kernel
3.10 LTS
Android 5.0 on Kernel 3.10 LTS
