-5V in “yellow” Scorpio

ZXNet echo conference «hardware.zx»

From Roman Borokhov To All 21 December 2006

Hello, All Is the subject needed only for RS-232?

From Stanislav Yudin To All 21 December 2006

Hello, Mikka_A Exactly! I was wrong :)

From Stanislav Yudin To All 21 December 2006

Hello, m.d. Yes. And if only a 3.5" drive is used, then it will be enough a power supply with only +5V voltage. +12V power supply for 1818VG93 is formed on the computer board from +5V.

Hello, CityAceE Cit> Yes. And if only a 3.5" drive is used, then it will be Cit> a power supply with a single voltage of +5V is sufficient. Power supply +12V Cit> for 1818VG93 is formed on the computer board from +5V. where did you see the converter on the yellow one?! it's on green. on yellow, alas, no.

From Roman Borokhov To All 21 December 2006

Hello, Mikka_A Thank you! Mik> on yellow, alas, no. The converter is easily added (I have a Pentagon-1024SL v1.4 that only powers from +5V) ;)

Hello, m.d. md> Thank you! md> md> The converter is easy to add (I have a Pentagon-1024SL v1.4 md> is powered only by +5V) ;) what scheme did you use?

From Roman Borokhov To All 22 December 2006

Hello, Mikka_A Mik> what scheme did you use? According to Scorpovskaya. And the 5V power supply is homemade, on LM2576, it can be powered from the mains or from battery :)

From Mikhail Andreev To All 22 December 2006

Hello, m.d. md> According to Scorpovskaya. And the 5V power supply is homemade, on LM2576, you can power it md> from the network, and from the battery :) Throttle - what kind do you have? (where did you get it, what does it look like, does it match the face value? diagram...) You can send the diagram either in a personal message or in BPshnik’s email.

From Roman Borokhov To All 22 December 2006

Hello, Mikka_A The power supply unit contains a ready-made choke from the Elektroniki D3-28 power supply unit (I just have two of them), in converter - standard, small (similar to a resistor), 20 μH. Power supply circuit - according to the datasheet.

From Mikhail Andreev To All 22 December 2006

Hello, m.d. md> in the converter - standard, small (similar to a resistor), 20 md> µH. .
