VM1000 / 5v tolerant pins / level shifting

Post by Lazar » Mon 2017-06-26 10:10

Dear Sir,
we are interfacing VM1000 with Arduino UNO (5v).
As far as we can tell, we do not need level shifting for Tx/Rx line after v1.61.
My question is: how can we know if our module is v1.61 or later hardware revision?

Best regards, Lazar

Hello Lazar,

The silkscreen has "VS1KMOD VLSI Solution 2014" for 1.61 and the lot identification is 2FIN2 or 2FIN3 (instead of 2FIN1).
