3.3.3J6, JMP5, JMP6, B1: Power Connectors

The MSC1211EVM features a flexible power supply. Externally generated power, the onboard regulator circuitry and supplied wall-wart, or a 9V battery can all be used to supply power. Furthermore, the separated analog and digital power supplies can be powered differently; e.g., the analog power supply can be powered externally, and the digital power supply can use the onboard regu- lator, at the same time; this is configured using jumpers JMP5 and JMP6. The exception to this is that the battery and wall–wart cannot be used at the same time (see following paragraph).

Four power connectors are provided: JMP5 (pins 2–3) and JMP6 (pins 2–3) for external power, battery terminal B1 for a 9V transistor radio battery, and J6 for the supplied wall-wart. J6 is a switched jack— connecting a plug to J6 auto- matically disconnects the battery terminal. This prevents the battery and J6 from supplying power simultaneously.

Battery power is regulated by the same circuitry that regulates J6 (wall–wart) power. Note that when a battery is connected to B1, approximately one half of the prototyping area is covered up by the battery.

Caution: Be very careful when connecting external power supplies to JMP5 (pins 2 and 3) and JMP6 (pins 2 and 3). They are not protected against reversed polarity. If you connect them backwards (i.e., with reversed polarity), it is likely that the MSC1211EVM will be permanently damaged.
