Before logging in, ensure that the serial port tools are installed on your PC. If you have not installed any serial port tool, refer to: Drivers and Tool Installation

Connect PI-SG565D to a PC

During development, communication with PI-SG565D is typically done via UART. First, locate the debug UART connector labeled "DBG_UART" on the PI-SG565D. Second, connect the USB-to-serial module Dupont cables to the debug UART (pin order from left to right: TX/GND/RX) of PI-SG565D. Third, connect the other end of the cables to a USB port on your PC (or USB Hub).

PCB UART Wiring:

  1. The black wire connects to the GND pin of the USB-to-serial module module.
  2. The red wire connects to the RX pin of the USB-to-serial module module.
  3. The yellow wire connects to the TX pin of the USB-to-serial module module.
  4. Place the jumper cap on the 3.3V power rail, as shown below:

After powering on, the serial port will output the following data:

Log in

The login account defaults to root when PI-SG565D is powered on, with no password required. Press Enter to log in directly. To modify the password or add new users later, use the passwd command.
