Debug My I2C Bus

By jeditekunum

2 layer board of 2.01 x 1.01 inches (51.0 x 25.6 mm).

Bus connector is documented here.

LEDs for 3.3VDC, 5VDC, SCL, SDA, ~INTERRUPT, and ~RESET. Non-power signals are all active low so this uses P-Channel logic-level MOSFET (such as IRLML6402) and current limit resistor (~220) for each.

SMD components are size 1206.
