Question MINI 560 resistor ?

[CIP060]

Hi, I've received the resistors but I'm having difficulty finding the correct voltage
These are my tests 2K 2.2V 3.3K 3.0V 4.7K 3.9V 4.4L (2.2+2.2 in series) always 3.9V
what do I have to put on the mini 560 to get 3.3 V???
If you could kindly give me the list of resistors you put in to get the correct voltage 1V 1.15V 3.3V 5V
Thank you I add that I got the mini 560 at 5V but the output voltage gives me 6.25 very strange this happens on all the mini 560s that were in the package
Looking at Jakara's video when he connects it he gives it 5.25 and it makes me strange

Those chinesium regulator modules are often made using multiple different chips in slightly different configs over time. It's possible that you have modules that require different resistance value to set the output voltage. This is one of the reasons why we don't recommend using cheap regulator modules like that.

Without knowing exactly what regulator IC is on your modules, finding the correct datasheet is pretty much impossible. Although, you could use a trim potentiometer in place of a static resistor and live adjust it until you find the desired output voltage.

สวัสดี ฉันได้รับตัวต้านทานแล้ว แต่ฉันมีปัญหาในการหาแรงดันไฟฟ้าที่ถูกต้อง
นี่คือการทดสอบของฉัน: 2K, 2.2V, 3.3K, 3.0V, 4.7K, 3.9V, 4.4L (2.2+2.2 ในซีรีส์) เสมอ 3.9V
ฉันต้องใส่อะไรใน mini 560 เพื่อให้ได้ 3.3 V???
หากคุณสามารถกรุณาให้รายชื่อตัวต้านทานที่คุณใส่เพื่อให้ได้แรงดันไฟฟ้าที่ถูกต้อง: 1V, 1.15V, 3.3V, 5V;
ขอบคุณฉันเพิ่มว่าฉันได้มินิ 560 ที่ 5V แต่แรงดันขาออกให้ฉัน 6.25 แปลกมากสิ่งนี้เกิดขึ้นกับมินิ 560s ทั้งหมดที่อยู่ในแพ็คเกจ
ดูวิดีโอของ Jakara เมื่อเขาเชื่อมต่อเขาให้ 5.25 และมันทําให้ฉันแปลก

ฉันหวังว่านี่จะช่วยคุณได้บ้าง

Today I put 4K and it gives me 3.42V probably 3.8 should give me 3.3V

วันนี้ฉันใส่ 4K และมันให้ 3.42V แก่ฉัน น่าจะ 3.8 ควรให้ 3.3V แก่ฉัน

3.8k โอห์ม คุณอาจต้องใช้ 3.3k โอห์มบวก 500 โอห์ม วิธีการทําเช่นนี้เป็นดังภาพนี้ ฉันทําสิ่งนี้ด้วย

ในกรณีที่คุณไม่มีตัวต้านทาน 3.8 k ohm

Then we are approaching the correct value of the resistance to reach 3.3V
This morning I put a 3.3K + 510 ohm resistor (3.810) the voltage is 3.40 V (too much?)
I have the possibility of trying with a 470 ohm instead of the 510 ohm one in order to have 3,770
Otherwise I have 330 ohm ones but I assume 330 is too low ?
would end up with 3,630 K

The voltage doesn't have to be exact in this use case. 3.4v is within margin

With this solution to find the right voltage and relative resistance value is a snap
I was losing entire days without a REAL solution
A question arises spontaneously
By adjusting to 1V in output I get 400 OHM as resistance value compared to the approximately 800 recommended
We are almost double as a value

 

[Stitches]

That's not uncommon for generic modules with poor documentation

 

[CIP060]

So based on the voltage I recovered the value of the resistance that can be put
Now there is another problem
though only some resistances give the voltage with resistances under the value of 1K does not give any output voltage
If I do not put any resistance the value of the output voltage is obviously the same as the input voltage (as it should be)
It seems that there is a problem in the regulators
Sometimes it seems that they go into standby and do not give any output voltage
Very strange this behavior

What do you think about this? it works well and is VALID

That is @ohkin86 's shop. that would be perfect for testing.

I’ve used that regulators to power my wii, and I had no issues while setting up my voltages, maybe your modules have a second feedback resistor which is slightly different compared against other modules

I remember that I’ve placed a 10k pot and I was able to regulate from 1V to 12V so maybe your resistor values are A LOT different
