Hi
My markdown beta and bare 1.0 boards arrived (:
Been soldering up the 1.0 first though (:
Noticed some points - correct me if fixed in 1.1 - have not checked the board layout this morning
1. Mini USB - I have about 5 brands and all have two little nibs that go into holes in the footprint, keeps it lying still and cant move while soldering. In your footprint these holes are nonexistant. This means i had to cut off the nibs, and had a fun time sliding it around while soldering? gEDA cool and all, but this is where Eagle excels - proper libraries
2. Crystal: No offloading Caps? This wont run reliable USB??? I am tacking some on the back but it HAS to be fixed
3. Silkscreen has imnproved for the previous beta i bought (:
4. C19 is a little close to the ATmega if used with a quality socket. Cheap bent socket it kinda works, expensive milled socket it overlaps. Move C19 a bit closer to drivers
5. Too many components under the ATmega- again difference IC sockets maybe but i have ones with reinforcement in the middle - had to cut out the pastic with side cutter, not ideal
6. I assume AUX1 is a SD Select Pin?
7. Area with AUX1, two caps for the therm, and temp1+2 headers are very closely bunched together - space out a little
