I want to buy the TellyMate Shield from
I´ve already contacted the support from batsocks.
The Mega8 (5v) on the TellyMate needs to see 3v on an input to guarantee reading ‘high’ (VIH = 0.6 * Vcc = 3v)
The LPC2388 (3.3v) can only guarantee 2.9v (VOH = VDD - 0.4v = 2.9v).
What do you think?
Does it work?
