Hello, I am about to attach RAK4631 with RAK13002 and RAK13004 as I need more IO(I2C) pins and PWM channels. However, it seems like RAK4631 only has one slot that accepts those extensions and the rest of slots seem to be small to attach either RAK13002 or RAK13004. Is there any way to attach them both on RAK4631 module? Thank you!
