| [* black] The motor power lines have some interesting (read: completely mismatched) color coordination going on—fixers take note. | |
| [* icon_caution] They could also do with some more support and insulation (hot glue) on the solder joints. | |
| [* black] Here's what we found on a quick tour of the main board: | |

| + | [* red] GigaDevice [http://www.gigadevice.com/product-category/11.html|GD32F103|new_window=true] ARM Cortex-M3 |
| [* orange] Six [http://ebldc.com/?p=147|half-H|new_window=true] bridge motor drivers, made up of two large MOSFETs each | |
| [* yellow] Two pairs of 0.007 ohm resistors by the power inlet (R007). | |
| [* icon_note] Resistors like these, with very low resistance, are used to sense current—helping to shut things down if a motor stalls out. |
