Large Digit Driver SER & CLK pin

Components & Accessories LEDs
1

I am planning to use ESP32 Thing to drive a set of LEDs using a Large Digit Driver. I am confused as to use which pins on ESP32 to drive the CLK and SER pin of the Large Digit Driver. Does it have to be this following configuration or I can use other GPIO pins too:

  1. Pin 18 - SCK(V_SPI_CLK) for CLK pin on Large Digit Driver

  2. Pin 23 - MOSI(V_SPI_D) for SER pin on Large Digit Driver

Thank you for your help in advance.

These connections should work. If there are pins that are configurable for SPI, as found in the datasheet: https://cdn.sparkfun.com/datasheets/IoT … eet_en.pdf, then they should work as well. However, there are some pins being used for the flash memory but at least they’re not broke out to the headers.
