2x Classic Nano
2x UNO R3
1x Chinese UNO with extra power pins and a different USB-serial adapter
1x Raspberry Pi 4 1GB
1x MEGA 2650 Pro (third-party created board.)
2x RF-nano (I don't know if these are ever going to get to my house.)
EDIT - I forgot about that sad, lonely Pi 0 W that I have as a NAS.
