This educational LCD oscilloscope consists of three parts: the base PCB, the display PCB and the rear panel. First
we assemble the display pcb and then the base PCB. On the display module we mount components on both sides.
We start at the solderside and finish with the components on the component side.
R1 : 220Ω (2 - 2 - 1 - B)
R2 : 560Ω (5 - 6 - 1 - B)
R3 : 1KΩ (1 - 0 - 2 - B)
R4 : 1K1
(1 - 1 - 0 - 1 - 1)
*
R5 : 2K4
(2 - 4 - 0 - 1 - 1)
*
R6 : 10KΩ (1 - 0 - 3 - B)
