 ICOP
 ====
 
-TODO
+ICOP makes industrial computer hardware and the development tools for them.
+ICOP offers an uncommon combination of hardware and software which distinguishes
+them from other board vendors.
 
+For a start, their products are not evaluation boards. They are ready-to-use
+industrial PCs. They are a complete solution electrically and mechanically.
+
+They are programmed with the Arduino IDE. You write your embedded application
+logic and UI using the Arduino framework and its library ecosystem. Arduino is a
+great abstraction to solve real problems when it's available for a platform.
+ICOP is one such platform. You have access to all the popular open source
+Arduino libraries. There is also support for installing Windows 11 on it.
+
+Inside most of ICOP's panel PCs is an x86 processor. They are DM&P Vortex86
+series chips. They execute 32-bit i586 machine code. This has interesting
+implications, especially since the programming environment is as low-level as Arduino.
+It's a rare case of an x86 CPU being used in a real-time setting.
+
+Panel PCs
+*********
+
+These are PCs which are designed to be mounted in a panel. They are more
+powerful than typical HMIs.
+
+QEC-PPC-M-090T
+--------------
+
+This is an x86 panel PC which you can program using the Arduino IDE.
+It has two cores. One core is dedicated to EtherCAT so the other is free
+for application logic.
+
+See the
+`LVGL port repo <https://github.com/lvgl/lv_port_icop_qec_ppc_m_090t>`_
+to get started creating a project for it with LVGL.
+
+See the
+`store page <https://www.icop.com.tw/product/QEC-PPC-M-090T>`_
+for documentation and the ordering information.
