# IPEM SIX - ESP32-C5 | ATM90E32 | WiFi 2.4/5GHz | Zigbee | Bluetooth | SIX Channel IoT Mains Power Energy Monitor

# June 2026: Example Code, to demonstrate and test the IPEM SIX

# Remember!
# - Set the BOARD to Use ESP32C5 Dev Module (or similar).
# - You can also set the BAUD rate up to 921600 to speed up flashing.
# - The SDK does NOT need external power to flash.  It will take Power from the USB 5V.
# - The Serial Monitor is configured for BAUD 115200

# The purpose of this test code is to cycle through the various main functions of the board as part of bring up testing.

# This test code is OPEN SOURCE and formatted for easier viewing.  Although is is not intended for real world use, it may be freely used, or modified as needed.
# It is distributed on an "AS IS" BASIS, WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied.

# For board configuration, see github.com/DitroniX/IPEM-SIX-ESP32C5-ATM90E32-IoT-Mains-Power-Energy-Monitor/wiki/Arduino-IDE
