#### Power budget
|

|
10 mW refresh for 25s
|
||||||
|
P=IV
|
||||||
|
10 mW = I * 3.3V
|
||||||
|
10 mW / 3.3v = I
|
||||||
|
I = 0.00303030303 = 3 mA
|
||||||
|
3 mA @ 25 s = 75 mAs
|
||||||
|
hour/sec = 1/3600 h/s
|
||||||
|
75 mAs * 1/3600 h/s = 75/3600 mAh = 0.02083 mAh
|
||||||
|
48 refreshes per mAh
|
||||||
|
500 mAh = max 5000 refreshes
