Normally with the MA, J3 (5V) only provides power to the Raspberry Pi below via J1. When J4 jumpers 1-2 and 3-4 are shorted, this apparently provides common J3 power (5V) to the MA and the top side GPIOs J2 and J3. J5 (3.3V "clean power") is then left unconnected. MA must have 3.3V regulators on board to supply power to the MA??
Question: What are the voltage readings of J4 jumpers when 1-2 and 3-4 are shorted? Are they both 5V or is 1-2 5V and 3-4 3.3V?
