6.1.4 DC-DC Transfer Board
F15 DC-DC transfer board connects to the 100w AC-DC power board and batteries, and
mainly transfers the 19.3V voltage outputted by the 100w AC-DC power board to direct current
required by F15 main control board and wireless transducer charging board, and controls the
transfer between the batteries and 19.3V voltage, ensuring normal operation of the product and
realizing power supply of the wireless transducer, main control board, multi-parameter module
and LCD display.
