MP5 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 Table 3
