4.3. Rechargeable Battery
The Battery will be recharges automatically while the IO Board is in use (RP6 is switched on).
Overloading is not possible.
Hint: You must enable the Trickle charger in the RTC (DS1339 – 2kOhm and Diode). Refer
to the source IOExtDemo Software and/or the datasheet of the DS1339!
Hint: There should be no need to replace this battery! Recharging will occure during
normal operation of the Robot. The data will be kept over several weeks.
5. Technical data
5.1. Supply voltage / current consumption (bus not active, no other connections rather than supply
voltage and GND).
VDD (PIN3, XBUS) = 5,0 V ± 2%
IDD = 15,00 mA ± 5,0mA
5.2. Servo Power Supply input voltage.
VSensor_PWR ≤ 10,0 V
ISensor_PWR ≤ 3,0 A average; peak load up to 5,0 A
depending on servo load
5.3. Gyro:
Vout = Vout(0) ± 10mV / dps ± 2%
Vout(0) = 2,5 V ± 2% (no motion)
Range = approx. 200dps max
5.4. Power switches:
Iout max = 0.5 A / continuous each channel / peak 1,0A
(5V regulator on base board might be limiting if all
4 channels are active at the same time.)
5.5. I2C Bus speed max. 400kHz
5.6. All other data according to IC data sheets (see chap. 3.)
