+# Left matrix controller
+The left-side matrix controller is tasked with directly controlling the 7 LED matrices on the left side of the head. The images to be displayed are sent over I2C from the [Main Controller](./MainController.md).
+
+## Connections
+### Main controller
+The main controller is connected via I2C1 on the following pins:
+- 19 (SDA)
+- 20 (SCL)
+- 38 (GND)
+- 39 (VSYS)
+
+### LED matrices
+The 7 8x8 LED matrices are connected in a chain via SPI0 on the following pins:
+- 22 (CSn)
+- 24 (SCK)
+- 25 (MOSI)
+- 28 (GND)
+- 40 (VBUS for VCC)

+# Main Controller
+The main controller is a Raspberry Pi Pico 2W. Its task is to send images to the LED matrices, and to directly control the transparent OLED HUD.
+
+## Connections
+### OLED HUD
+The OLED HUD is connected via SPI0 on the following pins:
+- 28 (GND)
+- 25 (MOSI)
+- 24 (SCK)
+- 22 (CSn)
+
+VCC to the HUD is provided by the VCC output on the left front LED matrix.
+
+### Left matrix controller
+The [left matrix controller](./LeftMatrixController.md) is connected on the same side as the HUD, via I2C1 on the following pins:
+- 32 (SCL)
+- 31 (SDA)
+- 38 (GND)
+- 40 (VBUS for VCC)
+
+### Right matrix controller
+The [right matrix controller](./RightMatrixController.md) is connected on the opposite side of the HUD, via I2C0 on the following pins:
+- 1 (SDA)
+- 2 (SCL)
+- 3 (GND)
+- 40 (VBUS for VCC)
