hi,

https://www.olimex.com/Products/MSP430/JTAG/MSP430-JTAG-ISO-MK2/resources/MSP430-JTAG-ISO-MK2.pdf read document.

I know powering the device from external source of power (12V) or via the USB(5V).

But,What is the minimum voltage applied to the external product?

Waiting for your help.

Hey Nurol,

When using only USB power - 40mA.

When using 12V external supply - 300mA.

hi LubOlimex,

Thank you for information but what is mınımum voltage ?

LubOlimex

Hey again,

It is 1.8V. There is also algorithm detecting the voltage applied on the controller - if it is below 0.7V (I believe) it will attempt to power it to programmable levels.

hi LubOlimex,

Thank you for your interest.

The JACK input so +12VDC,I'm asking minimum voltage?

Hi again,

Only 12VDC if choosing to use debugger powering - no more no less.
