1.1 wiki 2:
1.19 wiki 3: [ODROID-C1](http://www.hardkernel.com/main/products/prdt_info.php?g_code=G141578608433&tab_idx=1) was a $35 quad-core SBC from Hardkernel. ODROID-C1 support was introduced in NetBSD 7.0. It has been succeeded by the [ODROID-C1+](http://www.hardkernel.com/main/products/prdt_info.php?g_code=G143703355573), which is supported by the same NetBSD kernel.
