Yes, most likely. I remember only few of the many posts I read, so I am not sure.
Hi @jafu9613, welcome to the forum! Please read How to get the best out of this forum.
In the Displays section, we welcome posters to provide clickable links to the devices in question.
This allows faster and more precise answers.
And if the site with the Node MCU V3 has a pinout diagram, it might be obvious that these may not be the standard HW SPI pins for the board you compile for. NodeMCUs have pins that are not usable except for serial memory chips.
You could try with the suggested wiring of GxEPD2:
// mapping suggestion from Waveshare SPI e-Paper to generic ESP8266
// BUSY -> GPIO4, RST -> GPIO2, DC -> GPIO0, CS -> GPIO15, CLK -> GPIO14, DIN -> GPIO13, GND -> GND, 3.3V -> 3.3V
// NOTE: connect 3.3k pull-down from GPIO15 to GND if your board or shield has level converters
// NOTE for ESP8266: using SS (GPIO15) for CS may cause boot mode problems, use different pin in case, or 3.3k pull-down
// NOTE: connect 1k pull-up from GPIO2 (RST) to 3.3V if your board or shield has the "clever" reset circuit, or use a different pin
I think you selected the correct panel for the Waveshare 1.54" b/w V2.
I you still have problems, please provide diagnostic output from Serial Monitor, in a code window.
