A new powerful Raspberry Pi alternative has been launched by Khadas in the form of the VIM3 which is available as both a Basic and Pro version priced at $99 and $139 respectively.

The VIM3 uses an Amlogic S992X system-on-a-chip (SoC), the same SoC at the core of the Odroid-N2, which features four Cortex-A73 performance cores and two Cortex-A53 efficiency cores, as well as a Mali-G52 MP4 GPU, with support for 4K 10-bit video decoding at 75 fps for H.265 content.

Compared to the Odroid-N2, the VIM3 Pro also contains 16MB SPI flash, while the Odroid-N2 has only 8MB. It also features a MIPI-DSI display connector, a tri-axis accelerometer, and a dual-channel IR receiver.

VIM3 specifications include:

• SoC – Amlogic S922X hexa-core processor with 4x Arm Cortex-A73 and 2x Cortex A53 cores, Arm Mali-G52 MP4 GPU, built-in Cortex-M4 core for “always-on” processing
