Yes. The display breaks out the available pins from the display module.

However, keep in mind that these products are primarily meant to program the displays, and breaking out the extra pins is an additional feature.

On that note, the 5-way interface included in both programming adaptors is labeled:

  • 5-Way Interface  (gen4-PA)
  • uLCD/uOLED (4D-UPA)

is meant to program uLCD and uOLED products, not to breakout the display’s 5-way interface.

Therefore, if you need to breakout the Serial UART pins that are also used for programming, it is recommended to use a gen4-Breakout board or integrate the display directly into your application board.
