3.6 Proximity ? Capacitive ? Touch ? Sensor ?
Eight ? touch ? sensitive ? electrodes ? provide ? the ? primary ? user ? interface ? on ? the ? JM ? Badge ? Board. ?? Revision ? B ?
of ? the ? board ? features ? a ? MPR083, ? while ? later ? revisions ? feature ? a ? MPR084. ?? These ? touch ? sensors ? detects ?
capacitance ? changes ? on ? the ? eight ? electrodes ? and ? provides ? touch ? information ? to ? the ? MCU ? via ? the ? I 2 C ?
bus. ??
Note ?
The ? touch ? sensor ? featured ? on ? the ? JM ? Badge ? Board ? varies ? by ? revision. ? ? The ? revision ? is ?
marked ? on ? each ? board ? at ? the ? bottom ? of ? the ? back ? (component) ? side. ? This ? change ?
requires ? different ? firmware ? drivers. ? ? Take ? care ? to ? select ? the ? correct ? software ? when ?
downloading ? from ? the ? Can ? Your ? Badge ? Do ? This? ? website. ?

A ? MMA7260QT ? three ‐ axis, ? low ‐ g ? accelerometer ? is ? featured ? on ? the ? JM ? Badge ? Board. ?? Each ? axis ? has ? a ?
dedicated ? analog ? output ? that ? is ? connected ? to ? an ? ADC ? channel ? on ? the ? MCF51JM. ???
3.8 Expansion ? Connector ?
An ? unpopulated ? 30x2, ? 100 ? mil, ? through ‐ hole ? header ? allows ? access ? to ? most ? MCF51JM ? signals ? for ?
probing ? and ? expansion. ?? The ? header ? pinout ? and ? dimensions ? match ? that ? of ? the ? MCU_PORT ? on ? the ?
DEMOJM ? baseboard. ?? The ? table ? below ? provides ? the ? pinout ? information. ?
