Open hardware fans get a rare turnkey option from Olimex: a 7-inch Linux touch panel computer shipped fully assembled, with schematics and design files published for the board inside. The new LCD7-PANEL-LIME2 pairs the company's A20-OLinuXino-LIME2 single-board computer with a 1024 x 600 capacitive touchscreen, a panel-mount frame, brackets, and ribbon cable, and arrives with Linux already flashed to the board's eMMC and the touch panel enabled. No soldering or display-driver setup is required.
The brain is the A20-OLinuXino-LIME2-e16Gs16M, built on the dual-core Cortex-A7 Allwinner A20. It carries 1GB of DDR3, 16GB of eMMC, 16MB of SPI flash, Gigabit Ethernet, native SATA, HDMI, two USB host ports, USB OTG, a microSD slot, a LiPo battery connector with onboard charging, UART debug pins, and GPIO expansion headers. Compared with the older A20-OLinuXino-LIME, the LIME2 revision adds Gigabit Ethernet, doubles RAM to 1GB, moves to an 8-layer PCB with improved DDR3 routing, and reworks the LCD and GPIO connectors. The display itself is the LCD-OLinuXino-7CTS, and the LCD7-PANEL frame mounts it onto rigid panels between 0.5mm and 4mm thick using six spring brackets and two PCB brackets.
The A20's appeal for this kind of long-life embedded build is its software situation. The Allwinner A20 is the sun7i platform, and the linux-sunxi community has carried it into the mainline Linux kernel for years, with serial console, USB, SATA, Ethernet, and MMC/SD all supported upstream alongside the display engine. That means a panel like this is not locked to a vendor BSP fork. Olimex ships both Linux and Android images and currently recommends its own Olimage distribution for OLinuXino boards, but the open schematics and mainline lineage leave the door open for custom kernels, buildroot images, or your own HMI stack. Armbian carries community-maintained images for the LIME2 with current builds tracking kernel 6.18.30, offering Debian- and Ubuntu-based installs with desktop options including XFCE, GNOME, and Cinnamon. The board is also an officially listed target for FreedomBox, Debian's personal server project, with ready-made images available, and Arch Linux ARM maintains a dedicated platform page for it as well.
The combination targets touchscreen HMI and embedded console designs where integration time matters more than raw horsepower, and the all-in-one bundle removes the usual fiddling with display ribbon cables and driver overlays. The LCD7-PANEL-LIME2 is listed in stock at $115 (€106).
