EB063 & Alpha-TRX voltage in datasheet

Post by Dutchie_World_Wide »

Hi Guys,

The EB063 data sheet mentions that a voltage level shifter is used.
But the data sheet of the Alpha-TRX*** says the module can be used between 2-5 Volt.
Is the data sheet for the EB063 outdated or did I miss something in the Alpha-TRX datasheet?

Hello,

Looking at the microchip IC datasheet the absolute max voltage on VDD is 6V. i.e. 6V won't cause permanent damage but probably won't work.

The working VDD voltage is listed as 2V2 to 3V8.

I/O pins are listed as absolute max of VDD + 1V5.

Can you show me which datasheet your looking at?
