 ====== SUT AVR Assembler Laboratory Node Hardware Reference ======
+===== Introduction =====
+Each laboratory node is equipped with an Arduino Uno R3 development board, based on the ATmega328P MCU. It also has two extension boards:
+  * external, analogue and digital communication board,
+  * user interface board presented on the image {{ref>sutavrlabimage1}}.
+There are 8 laboratory nodes. They can be used independently, but to present collaboration, nodes are interconnected symmetrically with GPIOs presented in a hardware reference section below
+===== Hardware reference =====
+The table {{ref>sutavrlabtable1}} lists all hardware components and details. Note that some elements are accessible, but their use is not supported via the remote lab, e.g., buttons and a buzzer.\\ The node is depicted in the figure {{ref>sutavrlabimage1}}.

+===== Communication =====
+Devices (laboratory nodes) are interconnected in pairs, so it is possible to work in groups and implement scenarios involving more than one device:
+  * node 1 with node 2,
+  * node 3 with node 4,
+  * node 5 with node 6,
+  * node 7 with node 8.
+Interconnections are symmetrical, so that device 1 can send data to device 2 and vice versa (similar to serial communication). Note that analogue inputs are also involved in the interconnection interface.
+See image {{ref>sutavrlabimage2}} for details.

+<note tip>Nodes are interconnected in pairs: 1-2, 3-4, 5-6, 7-8. Scenarios for data transmission between MCUs require booking and the use of correct nodes for sending and receiving messages.</note>
