 ## BOM
 
 To build a Sweep you will need:
 
-* 2x promicro compatible boards
-  * **Important:**  On the *left* half of the Sweep the promicro's USB port must face *towards* the PCB, and on the *right* half the USB port must face *away* from the PCB (so that the promicro's components are visible).
+* 2x promicro compatible boards or 2 nice!nanos.
+* Sweep 2 controllers face down, if you want to flip, match the raw pin to the controller. 
 * 34 choc switches
 * 2x reset switches (optional)
 * Some little rubber feet/bumpers
+* **Important:**  On the Sweep Compact *left* half of the Sweep the promicro's USB port must face *towards* the PCB, and on the *right* half the USB port must face *away* from the PCB (so that the promicro's components are visible).
