Proto 1 Board Changes
Posted on June 18, 2012 in Category: Blog - 0 Comments
Just a few board mistakes I discovered while soldering up the first prototype:
- Forgot to put 5v to one of the chips
- Incorrectly traced my output power in one spot (nothing critical)
- Power switch holes too small
- Reset switch holes too small
- Need TX label on user port header
- Power input/switch needs improvements
- A trace on the ATMega is not grounded (but works anyway because it touches ground - but technically they are not connected in the CAD file)
- Power LED was not grounded
- Would be nice to have standard MK-II header for flashing the bootloader
- Would be nice to have header to match the Sparkfun FTDI programmer to upload sketches from PC
- Mounting hole collides with a trace and therefore grounds it (not critical for prototype)
- GPIO trace too close to another pin
