Heya,
Sleepy never sold assembled units with a choice of PI’s, only assembled with PI4/CM4 (as available) or as a DIY “no-pi” with just the control board.
But the assembled ones now are the best they’ve ever been. 4 USB connections, USB C power, RCA out over 1/8” jack and a set of micro-HDMI outs, only one of which can be used at a time though.
