+### Ordering and Assembly notes
+
+#### Inductor choice
+
+I've tested version of this PCB with inductors from Cenker 
+CKCS3012-4.7uH/M (C354557) and Microgate 
+MPIT3015-4R7M-LF (C486485). Any 30xx footprint coil inductor with >1A current rating and ~ 100 mΩ DCR should work ok.
+
+#### Indicator LED placement
+
+For some reason, JLCPCB has trouble with their part orientation for this LED specifically. I'm hoping that eventually they will sort their database out. In the meantime, it is worth verifying the part placement prior to assembly.
+
+The footprint silkscreen has two elements to help indicate the orientation of the LED: an extra line on the side to indicate Pin 1, and a little arrow that matches up with a corresponding arrow on the part:
+
+<img src="./images/kicad_led.png" width=400>
+
+For the v2.4 PCB, make sure that the arrow on the DFM points to the arrow on the footprint, pin 1 matches the extra line on the footprint, and the + pad matches up to the correct pad! 
+
+<img src="./images/dfm_led.png" width=400>
+
+This is how it will look when assembled:
+
+<img src="./images/photo_led.png" width=400>
+
+You can see the little bond wires from each of the three LEDs going back to the common anode, which is pretty neat.
+
+***NOTE THAT THE 5V ONLY BOARD (V1.3) HAS A ROTATED FOOTPRINT! YOU'RE WELCOME AND I'M SORRY.***
