COMPATIBILITY AND EXTENSIBILITY: Great RPi alternative with same form factor as Pi 3 Model B for re-use with existing cases and power supplies. Identically designed 40-pin header enables hardware re-use by maintaining same pins for functions like SPI, I2C, PWM, UART, and more. Powerful GPIO wiring tool, libretech-wiring-tool, is available on Github that can quickly toggle GPIOs and dynamically control dtoverlays for faster design, testing, and learning.

HIGH PERFORMANCE LOW POWER: AML-S905X-CC performs faster than a Pi 3 B+ while using half the power. It is designed with power optimizations to increase sustained performance under load and reduce failures due to input voltage and current. It is one of the first SBCs to support 4K multi-codec hardware decoding and features a highly performant OpenGL ES 2.0 GPU for accelerated 2D/3D.

HIGH PERFORMANCE DESIGN: Quad 64-bit 1.4GHz ARM Cortex-A53 Processors, 4K Ultra HD ARM Mali-450 GPU, 2GB of High Bandwidth DDR4, 4K 60FPS High Dynamic Range Display Engine for H.265 HEVC, H.264 AVC, VP9 Hardware Decoding and 1080P 60FPS H.264 Harware Encoding, Up to 40% faster than Raspberry Pi 3.

UNMATCHED IO PERFORMANCE: Equipped with superfast Gigabit Ethernet and lightning speed 5Gbps USB 3, Renegade will power through mixed workloads unlike any sub $50 SBC can dream of. Turn it into a NAS, Kubernetes cluster, file server, wire speed encrypted router/VPN, and more! The performance and possibilities are endless.

COMPATIBILITY AND EXTENSIBILITY: 40 Pin header enables hardware re-use by maintaining compatible alternate pin functions like SPI, I2C, PWM, UART, and GPIO. Additional design features include ultra high speed (UHS) Micro SD card support, onboard IR, ADC header, eMMC module expansion connector, and more. Form-factor compatible with Raspberry Pi 3 for easy migration. Software made for Raspberry Pi is not compatible!
