Note:
1. Brightness of the RGB LED will vary with the supply voltage. Due to manufacturing tolerances, functionality is not guaranteed
over the entire working range.
2. To optimize efficiency, EFR32MG24's internal DC-DC converter should be set in BYPASS mode when the input voltage ap-
proaches the output voltage, typically for supply voltages lower than 2.2 V. More details are found in EFR32MG24's data sheet.
3. Not recommended for use with rechargeable Lithium batteries. Most Li-Ion and Li-Po cells exceed 3.6 V when fully charged.
