anavi-macro-pad-8: Fix I2C protection resistors
Browse files Browse the repository at this point in the history
Resistors R13 and R14 had too large values. These are protection
resistors used in series on the SDA and SCL lines of the I2C. To
fix this issue the values of both resistors were set to 24 Ohms.

fixes #4
