5.1.2.2 Current Measurement Jumper
To demonstrate the low power consumption of PSoC 4/PRoC BLE, a two-pin header is populated in
series with the power supply to the PSoC 4 BLE. This can be used to measure current using an
ammeter without the need to desolder any components from the board, as shown in Figure 5-5.
