-Silkscreen mixed up for R1 and R2 resulting in reset button failing. R2 should be resistor closest to reset jumper and should be 10K. R1 is resistor closest to reset switch and should be 10R. Lots of silkscreen reverted to Fab layer somehow. Fixed in revision R +Version U - Silkscreen mixed up for R1 and R2 resulting in reset button failing.
