(made by me - 09/2019 from 2.1.4 BOM)
Ultravox reply: "The cart doesn't include items that the BOM says are sourced from eBay, Small Bear, synthcube, etc."
About partsourcing: check the price for the next price break ( 3 resistors are more expensive than 10)
for EU users: order from www.TME.eu standard parts, its cheaper as mouser
OLED Display:
make sure your OLED folow this pinout VCC-GND-SCL-SDA, very often shows the shop the correct pinout but deliver another type.
AND short the pins on the display side (where the Frontpanel is) to prevent shorts to the Frontpanel.
if you cant source the correct display (pin) use restore legs and bend they - use cable shrink tube to protect this for shorts
