The RK3368-uQ7 (codenamed 'Lion') is a micro-Qseven (40mm x 70mm, MXM-230 edge connector compatible with the Qseven specification) form-factor system-on-module based on the octo-core Rockchip RK3368. It is designed, supported and manufactured by Theobroma Systems. It provides the following features: - 8x Cortex-A53 (in 2 clusters of 4 cores each) - (on-module) up to 4GB of DDR3 memory - (on-module) SPI-NOR flash - (on-module) eMMC - Gigabit Ethernet (with an on-module KSZ9031 PHY) - USB - HDMI - MIPI-DSI/single-channel LVDS (muxed on the 'LVDS-A' pin-group) - various 'slow' interfaces (e.g. UART, SPI, I2C, I2S, ...)
