4.2 Power supply
The u-blox RCB-F9T timing board has two power supply pins: VCC, and VCC_ANT.
4.2.1 VCC: Main supply voltage
The
VCC
pin is connected to the main supply voltage. During operation, the current drawn by the
module can vary by some orders of magnitude. For this reason, it is important that the supply
