Preparing a wiring loom
67
68
If you want to prepare a wiring loom, these are some suggested wire lengths and connectors. They assume you lay out your electronics like shown
here
69
You find a corresponding layout_a4 pdf
here
70
You also need to solder pins to the Mechaduino's D0, D1, 20, 21, V+, GND, 5V, and 3V3 connectors.
71
This guide also doesn't include a wire for 5V power to the Mechaduino. Instead it assumes you've soldered a 5V regulator (for example a L7805CV or R-78E5.0-0.5)
72
The wiring diagram should be at the bottom of the assembly manual linked above. A direct link to the wiring diagram is provided
here
73
Same color means same signal, but not neccessarily same voltage, since i2c signal is converted between 3V3 and 5V.
