Markers are grouped by colour, from what you are most likely to need to what you will rarely touch:

Colour Group
🔴 Red Compute & storage — compute module socket, NVMe, microSD, battery
🔵 Blue Ports & connectors
🟠 Orange Buttons & switches — power switch, ESP32 BOOT / RESET, Pi BOOT
🟣 Purple Processors & control — ESP32-S3, keyboard MCU, USB hub, display MUX
🟢 Green Power management
🩵 Cyan Sensors & audio
⚪ Grey Other — internal-use ports and headers

The buttons you actually need are the orange ones; see Flashing firmware for how they are used.
