Question Midifying dr.110 - msa-p noob question

Hello Folks! I've just recently bought the MSA-P board with the intention of triggering the sounds on the DR.110. I'm a bit of a novice when it comes to DIY electronics, I've done a bit of circuit bending but that's about it, so excuse my lack of knowledge!

My question is, if I want to power the MSA-P with a source from the DR.110 where would the best/safest point be? I've had a poke around with the multi-meter and the nearest I can get to the 5v required for the MSA-P is 5.43v. Would the 5.43v be O.K to power the board or does it have to be exactly 5v?

Thanks in advance for any one who replies

All of the boards recommend using a 9V power supply as the input power to the boards. They have on board voltage regulators to provide a stable 5V to the CPU. The main reason for 9V is to allow the use of cheap wall warts that have poor voltage regulation -- the fine regulation is done right on the boards.

Therefore to answer your question -- if you have a very stable 5.43 volts, then it should work. The on-board regulator will take this down to the 5V required.
