CY8CKIT-042-BLE-A Bluetooth® Low Energy (BLE) Pioneer Kit Guide, Doc. # 002-11468 Rev. *A 95
Hardware
When the BLE Pioneer Baseboard is powered from an external voltage supply, remove the USB
cable from J13. Connect the positive terminal of the external voltage supply to the positive termi-
nal of the ammeter and the negative terminal of the ammeter to the upper pin of J15. Connect the
negative terminal of the external voltage supply to an onboard GND pin. Figure 5-7 shows the
required connections.
Figure 5-7. Current Measurement when Powered Separately
To measure the power consumption of only the module with coin cell, connect the coin cell directly to
the modules, as shown in Figure 5-8. The BLE Pioneer Baseboard is designed with additional
circuits to protect the BLE device and the F-RAM in an Arduino environment. Note that power
consumption measurements on the BLE Pioneer Baseboard will also include the power consumed
by these additional circuits.
Connect the positive terminal of the coin cell to pin J2.2 and negative terminal to pin J2.4 using
wires.
