Hey!
Could you please tell me what do you mean by “ It can be woke up only by the middle button.”?

As the schematic shows it should be powered on by both of the buttons or if not then which one is the middle button?

Thank you!

Hello, I encountered "No hardware SPI pins defined. All SPI access will default to bitbanged output" when I was porting to arduino. Is there any impact on this?

Hi!
Thanks for posting a good project!
On Instagram, you wrote about the problem of automatic firmware management via USB
In your circuit, there are no resistors in a pair of transistors.
They are present in the official scheme of NodeMСU.
Maybe this is the problem?

Hello all,

Thanks for creating such an awesome project! I really learn a lot from looking at the schematics and code.

For a project I am working on I wanted to use the USB-C part from your schematics. However I find many different variants of the USB-C, some with just 6 pins, up to 32 with many options in between. In your schematic you use one that only shows 7 pins, do you maybe have the exact component name of the USB-C you have used?

About the battery part I had also a question, you use the XB5353A (protection) and MCP73831 (charge) to manage the LiPo battery, I'm wondering if these IC's allow the battery to be discharged at the same time it's charged? The TP4056 for example does not allow this, since this can result in an overcharge failure detection, but I'm unable to find anything about it in the IC datasheets you have used.

Thanks for any help :)

Hello sir , i saw your work its awesome. I am little confused about the battery protection circuit. Its a P channel mosfet you used there and gate connected with the Gnd. Can you please explain me how it works because protection ic have its own VM which also connected to Gnd. I really want to know how this circuit work's

Hi @makermoekoe, thanks for sharing your sources. I saw your video and was inspired, and thought I could "steal" some of your design for my work.

However, stealing is not nice, so I'd rather work with permission. It would be very neat if you could provide a license for your work, such that it becomes easy to get inspired by take some parts of it, and create more awesome stuff.

If you don't want to bother with this legal stuff and just want to allow everything, consider CC-0 as a license. Otherwise, the other CC licenses are usually a good choice for this kind of work.

Thanks!

Edit: I just found this awesome new wizard for choosing a CC license. Of course, alternatives to CC would also be very nice, see for example choosealicense.com.

Hi Sir,
thanks for your sharing such excellent project.
I have a question about the latching circuit. How does it works, could you explain it please? I can find some basic work flow of it.

• while USB insert, EN_LDO high, it will enable the LDO.
• Button 1 or Button 2 pushed, EN_LDO high, it will enable the LDO.
• LATCH low, power off LDO, right?

Why there are tow button, how about just one button?

Greetings!
This is so neat product :)

Does the latching circuit send higher voltage to MCU?
BUTTON and BUTTON2 are only connected with 1K, 5.1K resistor,
so VCC(4.2V) divides to 3.51V, is it okay for the 3.3V MCU GPIO?

Thank you so much

Have you thought about replacing all the power supply controls with a microcircuit PMIC (Power Management IC)?

Example: X-Powers AXP173
It already contains:

• Power Path (Power selection BAT/USB)
• 2 DC/DC
• 4 LDO
• Charge control
• Gas Gauge (how much charge is left in the battery)
• Button On/Off
• QFN-32

Using PMIС would greatly simplify the circuit :)
