I have a 3.3V, 5V, and 12V DC-DC Multiple Output 6-12V Input Voltage Converter Module, but I want the 6V version and I'd like to find a shield-like adapter instead of a converter. I've searched a lot but couldn't find one. What do you recommend I do?
I don't want a specific solution for the card. The cards I use really vary, but I generally use esp32. I am currently looking for a solution for esp32.
You are talking about two different things, so the answer has to be no, but I suspect what you want is a carrier board for one of the ESP32 pin arrangements, plus an onboard multi-voltage set of pins. If that sounds close, search on the carrier. Make sure it is for the specific ESP32, I have ESP32 with 30 pins and some with 38.
I'm using an ESP32-S with 5V and 3.3V, but I also have an ESP32 (ESP-WROOM-32) with a 3.3V VIN. What I want is to connect the GND to GND, the 5V to 5V, then connect a 9V battery to the 6-12V jack input to power the ESP32, while providing specific voltages for the other components. I want it to be as practical as possible. Right now, I'm looking for something that works with both 5V and 6V.
I suggest you get a few of these and place in a nice box. You can use one old laptop power supply to power it or even a hearty battery if you want. You will need one for each voltage you want. They cost about the same as a pack of cigarettes. I use several of these, they work very well.
Thank you for your suggestion , it's a really practical solution for the power supply. However, I'm currently having problems when I connect the sensor's grounds to the board in common and the VCC separately. I even managed to provide 6V like this: in Figure 1, I set it to 9V, connected the ESP32's 5V and ground to Figure 1, then connected Figure 2 to Figure 1's USB input, and from there connected the VCC and ground to the sensor. The sensor also works at 5V. To be sure of the voltage, as I said, I also connected it to a different VCC and connected Figure 2 to the PC, the ground and VCC terminals to the sensor, and the other ground to the ESP32. I gave all voltages between 5.0-6.1V, but it didn't work with any of them. It requires a direct connection; it works at 5V, but for it to work correctly, 6V is needed. This 6V needs to be direct. Hi Tom thank you for your help, 6V is necessary for my sensor, and I don't want to go into too much detail and make the topic too specific (I can write privately). I hope this doesn't hinder the resolution of this problem too much. I really want to solve this problem; I've lost 2.5 months.
How much current are you planning to draw at 6.0 Volts? Fairchild manufactures a LM7806 voltage regulator. TO220 case good for about an amp. You can also use a LM7805 changing the ground reference.
Can you please post a copy of your circuit, a picture of a hand drawn circuit in jpg, png?
Hand drawn and photographed is perfectly acceptable.
Please include ALL hardware, power supplies, component names and pin labels.
A small piece of stripboard with some male and female headers can give you all the pins you want. Just don't overload it.
You can stack boards with shared lines or make up a backplane.
In complex wiring arrangements, it's quite common to use backplane systems like 19" racks with plug in boards doing different functions.
You could look at post #13 and use regulators to custom build whatever you want. If there isn't a fixed voltage solution, there are always adjustable solutions.
If you do a lot of projects, investing in a bench power supply can save tears.
I'll try post13; I thought about it before, but as far as I remember, I gave up on it because the current wasn't sufficient. Right now I only have the 5V version. If I order the 6V version tomorrow, it will arrive sometime during the week, and I'll have a chance to try it on Friday. I hope it works as I want. The ESP32 I siliconed for the project doesn't have a VIN line. I have a model with a VIN line. Should I connect VCC to the 6V and the 6V to the VIN? Wouldn't this damage the ESP32, or did I misunderstand? If the first method doesn't work, I'll try this. After all, 6V shouldn't damage the ESP32 too much in a short time. If the problem persists after trying both methods, I will create a detailed digital circuit diagram of the part I'm having trouble with, and I will also post a photo of the project here along with the diagram. Maybe I've made a very simple mistake in theory or practice.
The ESP32 is a 3V3 processor. It will get damaged with more than 3V6 on any pin.
If you use a voltage regulator to drop 6volt to 3.3volt, note that it has to work harder with a higher input voltage. It will get hotter and could fail if siliconed in, possibly taking the ESP down with it.
Leo..
I was momentarily distracted and bought 78L06 instead of LM7806.Next, I connected the VCC of the sensor, which requires 5V, to the Input and 6V to the Output.It worked for a short time, then all the sensor lights went out.
