HL6528RD vs HL6528

IoT Modules Legacy HL Series

Hi guys,

What are the differences between the old HL6528 and HL6528RD?

We had to redesign the power supply section after we found that the VBATT/VBATT_PA is now maximum 4.3V only.
Previously it was 4.5V. Out power supply PMIC produces 4.4V maximum. :frowning:

Other than this, what are the other differences?
And why introduces a new variant?
