But the AR100 is extremely underutilized, and takes good advantage of this by repurposing it to those real-time tasks associated with a 3D printer controller. See that small box labeled AR100 at the top of the block diagram? Meet the AR100, a controller originally intended to manage low-power operations of the A64.
It turns out that there is already a secondary microcontroller hidden in plain sight, integrated into the A64 itself. could have addressed this problem by putting a secondary microcontroller on the board, but he found an even more elegant solution instead. “But Linux is not a real-time operating system”, we hear you cry, “and controlling stepper motor drivers from an A64 SoC is just asking for trouble”. The Recore board is powered by an AllWinner A64 system on chip (SoC) which packs four ARM Cortex-A53 AArch64 cores running Debian Linux. The applications include Klipper, a project we wrote about when it was first introduced, and the OctoPrint print server. ’s design merges these together into one compact 12 x 12 x 4 cm package. Many setups also have a second computer, often Linux-based, which is dedicated to supporting tasks like running an Octoprint server and interfacing to a digital camera to monitor print progress remotely. The typical 3D printer has a dedicated controller which handles the real-time aspects of driving stepper motors. Charbax also mentions that the Allwinner A64 Remix OS laptops may be crowdfunded later on.No stranger to the world of 3D printers, from the workshop has released a new controller board called Recore. Those are probably reference designs, so the exact price will depend on the manufacturers themselves, and it’s also unclear when they’ll ship. They don’t come with a touchscreen though, so they’ve come with a third 11.6″ 2-in-1 model with a touchscreen, and either Allwinner A64 or Allwinner A83T octa-core processor that should be cost less than $100.
Those two models are expected to sell between $80 and $100 depending on the final specs such as battery capacity, and overall build quality. It features HDMI output, two USB 2.0 ports, a micro SD slot, and a 3.5mm audio jack. The second model is based on the hardware, except the screen is larger (14.1″). The first model is a white 11.6″ laptop (1366×768) with Allwinner A64 quad core Cortex A53 processor, looking quite similar to Olimex DIY laptop prototype also based on A64, with 1 to 2GB RAM, 8GB to 32GB flash, and a “nice keyboard and touchpad”.
But Charbax has showcased a few Remix OS laptop prototypes based on Allwinner A64 processor, with the video apparently shot from Allwinner office. Remix OS is a fork of Android making the popular operating system more suitable for desktop use with a start-up menu, better handling of multi-tasking, multi-window support, etc… It’s found in several tablets and TV boxes including Jide’s own Remix mini.
