I got the board in my hand sleep The mode is 8. 8ma around. enter standby The mode is 3. 8ma.
Why is it the same as the chip manual sleep for 1ma, standby for 15uA That's a long way off
The specifications describe the chip current, It's on the development board CH340, LED Etc, They're all power-hungry devices, If you want to measure the exact current, It is recommended to remove excess peripherals, retest.
unlit LED There will also be power consumption, Still only lit power led Power consumption is what it is
