62 -The FTDI chip can be powered through the on-board USB or with an external power supply through the XT60 connector. The 5V from the USB will only power the FTDI chip and the XBee compatible wireless module (if inserted) and won't power the servos. To power the servos, an external power supply (6V to 12V) is needed (more information in the "LSS - Electrical" section). If both USB and external power supply are connected at the same time, the external power supply will be automatically selected to power the FTDI chip and XBee module if it's higher than 7V. The external power supply can be a battery or an AC-to-DC wall adapter with the appropriate barrel to XT60 converter (more information in "[[LSS - Electrical>>doc:Lynxmotion Smart Servo (LSS).LSS - Electrical.WebHome||title="LSS Electrical"]]" section).
62 +(2) LSS servo connectors

64 -The adapter can operate on an external supply from 7V to 25V DC. Note however that the LSS actuators are intended to operate at between 6V and 12V. If the board is supplied with less than 7V, the 5V pins from the internal regulator may supply less than 5V and the adapter may not function properly. Using more than 25V may damage the 5V regulator.
64 +(3) Automatic switching between USB and external (VCC) power
65 65  
66 -**Arduino :** In the case where the LSS Adapter is stacked on top of an Arduino Board, the Arduino board can be powered from the Vin pin which is directly connected to the external supply voltage of the LSS Adapter. If the Arduino Board is powered separately via another external power supply (ex barrel connector), the “Vin cut” solder bridge on the bottom of the LSS Adapter Board needs to be cut. The ‘“Vin cut” solder bridge doesn’t need to be cut if the Arduino is powered through USB.
66 +(4) VCC and GND pins

68 -**Raspberry Pi : **It is recommended to power the Raspberry Pi separately using an appropriate power supply. This [[Raspberry Pi Power Supply 5V 3A>>https://www.robotshop.com/en/raspberry-pi-power-supply-5v-3a-micro-usb.html]] can be used to power the Raspberry Pi.

70 -**Other MCUs : **The 5V or the 3.3V outputs can be used to power other MCUs/Controllers. The 5V supply can provide up to 1A and the 3.3V can provide up to 500mA.
70 +The FTDI chip obtains power from either the on-board USB connector or with an external power supply through the XT60 connector. The 5V from the USB will only power the FTDI chip and the Bee socket (if a module is in place) and won't power the servos.

74 +In the case where the LSS Adapter is stacked on top of a shield-compatible Arduino microcontroller board, the Arduino can be powered from the Vin pin which is directly connected to the external supply voltage of the LSS Adapter. If the Arduino Board is powered separately via a different external power supply (ex. connected to the Arduino's barrel connector), it will NOT provide power to the LSS Adapter. The LSS adapter is designed to power the Arduino, but not vice-versa. As such, it is suggested that only ONE 6-12V power source be connected to the LSS Adapter which is used to power everything.

76 +**Raspberry Pi**
77 +
78 +The LSS Adapter's onboard 5V regulator does not provide enough current to power a Raspberry Pi and as such it is recommended that a Raspberry Pi be powered separately using an appropriate 5V, 2A+ USB wall adapter or 5V voltage adapter.

If both a USB and a 7V or higher external power supply are connected at the same time, the external power supply will be automatically selected / preferred in order to power the FTDI chip and Bee module. If the board is supplied with less than 7V, the 5V pins from the internal regulator may supply less than 5V and the adapter may not function properly. The external power supply can be a battery or an AC-to-DC wall adapter with the appropriate barrel to XT60 adapter.

89 +The four pins of all six connectors on the board are connected to one another. Each connector (on both the board and on each servo) can handle a maximum of 3A. The LSS Adapter is intended to provide sufficient current to all six connectors. In higher current applications, be sure to select a power supply / source which can provide the necessary current for all servos.
