Last post by GUNHED - Today at 01:01Quote from: angelcaio on Yesterday at 17:34Extenal power for the Mother X4 can be a good thing, as long as you feed the same power into the CPC.Quote from: GUNHED on 13:20, 12 August 25GT64/65 are 40 years old now, they deliver too few power. Try to use more PSUs for expansions. Never get power directly from the 5 V line of the monitor if you can use an extra PSU.My MX4 Version is "without Diodes" and not has power connection:
https://www.cpcwiki.eu/forum/amstrad-cpc-hardware/issue-with-a-mx4-board/msg168022/#msg168022Can I try powering the AMX Mouse separately with a 5V 2A PSU
And should I power the CPC with a 5V 4A power supply instead of the GT65?

Quote from: seanmcmanus on Yesterday at 21:25It says you might have to add your own ROMs so I don't know how easy that will be, but it's great that the CPC is now included.Probably just a download from CPCWiki or CPCPower.

Hi Brocky,
The ESP32 is 3.3v and the port is 5v active low. I didn't want to risk feeding 5v into a 3.3v chip hence using the ULN2803A. It might work direct, I wouldn't like to try. I'd be too scared about frying something in my 464

Quote from: Brocky on Yesterday at 16:43i ordered 5x the components (including the picos) from digikey all in one order just over the $60 threshold to qualify for free shipping...
Yeps, too bad. France is as far as it can be from australia
That's about the prices I have for 5x indeed. I agree it's not a huge saving, but quite some people prefer to pay 1/5 of that..

Last post by angelcaio - Yesterday at 19:59Quote from: Brocky on Yesterday at 17:45There is no power socket on my MX4 board, it is powered from the 464 expansion port and I cannot power it any other way.Quote from: angelcaio on Yesterday at 17:344A power supply is a bit high... remember if anything shorts its going to pull as much amerage as it can... 4A@5v is 20watts...thats alot of heat to dissipate..and will cause chips to burn up if there is a short...Quote from: GUNHED on 13:20, 12 August 25GT64/65 are 40 years old now, they deliver too few power.

the cpc464 itself doesnt need much more than about 800mA, so a 2A supply is plenty enough to drive the CPC and expansions...
im not sure what you mean about a MX4 "without diodes".. mine has none... and it can be powered externally by connecting power to the header and changing a jumper on the MX4..
I can power the AMX mouse separately because it has its own independent power outlet And from this comes a cable to the 464 power supply
This consumption will no longer depend on the 464
