XIAO RA4M1 Examples for timer interrupts?

Hello all,

two questions about RA4M1:

  1. Are there any examples for timer interrupts with RA4M1?
  2. More than a year ago I reported that the RA4M1 had too much noise in the ADC results, and Seeed figured out that’s because of too much noise on the ADC’s power supply. “We changed the R4 from 0Ω to 15Ω”. But this has never been changed in the schematic diagram. When I order new RA4M1 modules now, do they have the 15R resistor?

Thanks, Michael
