Programming and Setup Notes

Use the COM-labelled Type-C port for the direct COM connection. For programming through the native USB port, holding BOOT while connecting may be needed for the programming port to appear. The supplied factory program lights the RGB indicator when connected to WiFi and switches it off when disconnected.

Voltage note: The listed 3.3–5 V working range refers to the board power specification, not a statement that its GPIO pins accept 5 V signals. Verify the board pinout and electrical limits before connecting external hardware.
