HOMURA mainboard HMR-KK04 (Spring, 2011)


HMR-KK03の問題点

・電池残量の監視を行うように作られていない.

このため,HMR-KK04を作成した.基本的にHMR-KK03から大きな変更はない.ただし冗長な機能を削除した.またカメラモジュールの変更によりカメラへの供給電源を5Vに変更した.

Battery voltage RR (1/4 att) AN17 -
Battery voltage RC (1/4 att) AN18 -
Battery voltage RF (1/4 att) AN16 -
Battery voltage LR (1/4 att) AN24 -
Battery voltage LC (1/4 att) AN26 -
Battery voltage LF (1/4 att) AN25 -
Acceleromete X-axis AN27 Vref+ = Vdd
Acceleromete Y-axis AN28 Vref+ = Vdd
Acceleromete Z-axis AN31 Vref+ = Vdd

NOTE

GPIO pins of B11 and B15 must be set as INPUT and are unusable.

ADC of the accelerometer outputs must be done as Vref+ = Vdd (3.3V).
