Method 1: Boot button only

You can put your device into boot mode with only the boot button and a pin.

1. Position the PLT-1B as shown in the image below and locate the small opening to press the boot button.

Open PLT-1B case with a tool pointing to the boot button on the PCB near the USB-C port

2. Use a pin to press and hold the boot button, while holding the boot button plug the PLT-1B back into your computer/power and then release the boot button

3. Continue with uploading the firmware

Method 2: Boot and reset buttons

You can also put your device into boot mode by holding the boot button down while you press and release the reset button.

1. Plug in the device

2. Put your PLT-1B in boot mode. Use both buttons, in this order:

  • Press and hold the boot button (next to the USB-C port, shown in the images above). Keep holding it.
  • While you're still holding boot, press and release the reset button (labeled RST, shown in the images below).
  • Let go of boot.

Keep holding boot the whole time

Pressing reset by itself only restarts the PLT-1B. It goes into boot mode only when boot is held down while you press and release reset.
