Line 47: Line 45:
 RoboCORE cannot be supplied from the USB port of your laptop. Why? This is a robotic controller and has motor drivers on its board. Motors cannot be supplied from USB due to the current and voltage requirements. To avoid the risk of damaging the USB port we decided to supply RoboCORE separately. RoboCORE is designed to be programmed wirelessly and USB connection is not the basic way to program or supply the controller. RoboCORE cannot be supplied from the USB port of your laptop. Why?

-How much current does it need? This strongly depends on the robot configuration. A RoboCORE without any devices connected needs up to 80mA (180mA with Intel® [[edison:​start|Edison]]). When you connect certain motors, current peaks can reach several amperes. The average current should not exceed 4 A, otherwise the overcurrent protection will be triggered and unexpected resets will occur. Remember this when you are designing your robot. ​+How much current does it need? This strongly depends on the robot configuration.

 RoboCORE has two internal voltage regulators. The input voltage VIN is converted to 5 V by a switching regulator, and then to 3.3 V by a linear voltage regulator. Be aware of the current limits – the total current must not exceed 2 A through the 5 V line and 800 mA through the 3.3 V line. We will also remind you about power limitations in the description of individual interfaces. RoboCORE has two internal voltage regulators.

 +=== Power supply alternatives ===
 +
 +In most cases, the 6*AA battery holders are provided with RoboCORE. If you are not willing to use alkaline batteries, the first alternative is to use NiCd or NiMH rechargeable batteries - but they have much lower nominal voltage.
 +The better alternative are Li-Ion or Li-Poly batteries. Fortunately,​ these are available in the same shape as AA batteries and they are called "​14500"​. The name comes from dimension 14x50mm. ​
 +
 +Some examples:\\
 +[[http://​www.aliexpress.com/​wholesale?​catId=0&​initiative_id=SB_20160428221617&​SearchText=14500+rechargeable|14500 reachargeable battery on AliExpress]]\\
 +Of course, you also need a charger for them.
 +
 +Remebmer that Li-Ion and Li-Poly batteries have higher nominal voltage and you have to use 3 cells instead of 6 cells. To do that, you can:
 +  * use one 3*AA battery holder with 3 Li-Ion/Poly batteries,
 +  * use 6*AA battery holder with 3 "​dummy"​ batteries and 3 Li-Ion/Poly batteries.
  
 +The "​dummy"​ (placeholder) batteries examples:\\
 +[[http://​www.aliexpress.com/​wholesale?​catId=0&​initiative_id=AS_20160428223009&​SearchText=AA+placeholder|AA placeholder on AliExpress]]\\
 +They cannot be charged - they are only the "​link"​ to omit 3 unnecessary places in the battery holder.
