4x PCBs on one 100x100mm
there is no V-Groove, you have to cut it on the marking
groove it on top and back, with a new sharp cutter, do it several times, then break it
With this Method you pay for 20 PCBs 8€ all inclusive to EU-Austria
So you can Stuff 5 LRE8x2 with this.

There are 1Row 7Pin headers (2.54mm pitch) on the Backside of the PCB
The Values are printet on the PCB. Following Quantity is for 4 PCBs:
8x 1K 1208 SMD Resistors
12x 10uF 1208 Capacitors (non polarized)
8x 0.96“ SSD1306 Screens
3x 10K 0603 SMD Resistors which are optional
these are the parts which must be handsoldered
