(1) R12, R14, C31 and IC7 STM32F031F6 already populated on PCB
(2) alternatives: 1N5817, LL5817 MELF, SM5817, SS12, also higher rated parts like *5818, *5819, SS13, SS14
(3) you can also use MCP6002, note that ​
(4) SMT headers delivered with PCB set
(5) v1.2/v1.3 PCB has also pads for a 6-pin SPI OLED, but there are two different versions available!
the supported pinout is: VCC, GND, CLK, MOSI, /CS, D/C - THIS IS UNTESTED, TRY AT YOUR OWN RISK
(6) in very rare cases the ZeroScope might not boot up correctly depending on the power supply used, then increase C6 from 100nF to 1uF.
