3.3 Measure power-saving mode current for TLSR826XDK48
To measure current consumption of Telink TLSR826XDK48 board in deep sleep
or suspend mode, please follow the connection steps below:
1) Follow the steps in section 3.1 to download firmware into the TLSR826XDK48.
2) Power off the TLSR826XDK48.
3) Remove the jumper cap from J9 of TLSR826XDK48, as shown in Figure 5.
4) Connect anode (+) and cathode (-) of an amperemeter with anode (+) of 3.3V
power supply and PIN6 of J3, respectively.
5) Connect cathode (-) of the 3.3V power supply with PIN3 of J3.
