Description
Board
ESP32H2
Device Description
Devboard, Supermini
Hardware Configuration
nothing connected
Version
latest development Release Candidate (RC-X)
IDE Name
Arduino IDE
Operating System
Windows 11
Flash frequency
80MHz
PSRAM enabled
no
Upload speed
921600
Description
The device require too much energy in active and sleeping mode.
- not clear, why there are so many peaks with 100mA
- sleeping current is in my case about 450uA - too much. Any idea how to minimize it for ESP32H2?
-
- maybe other request - provide a light sleep example without needed rejoin

}Debug Message
No errors in debug
Other Steps to Reproduce
disabled USB CDC, debugging for saving energy.
Have removed the internal temperature procedure and replaced with random value.
Have used Nordic Power Profiler Kit II for measurements with 3.3V power
