Though you can program BiBoard directly or NyBoard with the USB uploader, external power is required to drive the servos separately.
When the mainboard is powered by USB, the blue LED lights up. When external batteries power the mainboard, the yellow LED lights up.
Rechargeable Li-ion Battery
Model: ZCF503060
Rated Capacity: 1000mAh/7.4Wh
Input: 5V-1.5A
The servos require 7.4~8.4V external power to move. Our customized Li-ion battery has a built-in charging and protection circuit. Clicking the battery's button will show its status. Blue light indicates it has power, and red means the power is low. Long-pressing the button for 3 seconds to power on/off the battery.
Be careful with the polarity when connecting the power supply. The terminal on the main board has an anti-reverse socket, so you won't be able to plug in the wrong direction. See here for the detailed connection instructions. Before powering, insert the battery's plug into the main board's terminal.
Reversed connection may damage your NyBoard!
It can last hours if you're mainly coding and testing postures or less than 30 minutes if you keep Bittle running.
The battery light will turn red when the power is low and will soon be cut off automatically.
Use a 5V-1A USB charger to charge the battery. We don't recommend using fast chargers. The battery will NOT supply power during charging. Keep the battery in your sight when charging.
During the charging process, the red LED light is on.
When the charging is finished, the green LED light is on.
