The resistor should be a 20K 0805 SMD, and the jumper (two middle pins) should be a right angled 2 pin connector if you want selectability, otherwise just bridge the small solder pads.

LED sampler with constant-current drive. Current mirrors ensure each LED is driven by (roughly) the same current. Not for beginners (0603, SOT-363).
Uses Bel 0ZCJ0050AF2E PTC fuse, AP2112-3.3 LDO (for setting reference current precisely, but also supplies the LEDs), 330R resistor sets current to around 5mA per LED, Diodes DMN32D4SDW dual N-MOS (needs sorting) in SOT-363.
