Hi,
What is chip revision of module?
regards,
Zahari
I programmed the board with this Arduino code:
https://github.com/espressif/arduino-esp32/blob/master/libraries/ESP32/examples/ChipID/GetChipID/GetChipID.ino
and it reports the following:
ESP32 Chip model = ESP32-H2 Rev 1
This chip has 1 cores
Chip ID: 16776800
Hi
Thank you. As i know there two revisions exist 0.1 and 0.2.
I need info from boot log "Chip rev"
