 ## Updating over UART using DFU mode
 
 1. Disconnect main connector. If you are going to apply +12V power through main connector - make sure that nothing else is connected to WBO (LSU sensors, any load, etc). But I recommend flash using +5V from USB.
 
 3. connect USB to uart connector to J3 connector: gnd, rx and tx.
 Don't forget to cross Rx-`Tx (adapter's Tx goes to WBO's Rx, WBO's Tx goes to adapter's Rx).
-If you going to power WBO from USB port - also attach 5V line. Do not connect +5 from USB adapter if you are going to use +12V supply through main connector.
