Source at commit a18d5969bd1582a6bc4623cdd0ee3d19b74d8627 created 13 years 6 months ago. By Werner Almesberger, Next part of board bringup: reset and power cycling. | |

1 | - changed C7 to 1 nF to debug a signal attenuation problem. Turned out to be |
2 | a bad trace. According to simulations, 22 pF should be more than enough. |
3 | |
4 | - added wire connecting uSD-side ground plane to ground plane at outer edge, |
5 | to improve CLK signal return. (Probably unnecessary, too.) |
6 | |
7 | - the footprint of the transistor (Q1) is reversed :-( It works after |
8 | converting the chip from SOT to PLCC. |
