Re: NanoVNA does not want to start -solved
You are right, the PDF is from the IP5306, but the pin 5 commands work the same. I post it anyway.
It is a good alternative. I no longer need the on/off switch.
cheers,

Could someone please add the PC software for NanoVNA v1.03 (or if there is a newer version) to the Files section? It would also help if Mac and Linix versions were added. Bob

Chinese sellers are VERY sensitive to demand and will raise asking prices quite quickly on any hint of a pick up in demand.

Re: NanoVNA does not want to start -solved
I noticed this phenomenon, which may be capacitor problems, and replacing all 10uf (C1 45 46 49) and 22uf (C47) capacitors can resolve the issue. You can try it, good luck!

Re: NanoVNA does not want to start -solved
I found a short write-up on the 5306 specs & on/off functions at :
IP5306 Datasheet ¨C Mobile Battery Power SOC
Posted on April 27, 2018 by Pinout
Part Number : IP5306
Function : 2.1A Charging 2.4A Discharge Highly Integrated Mobile Power SOC
Package : ESOP 8 Pin type
Manufactures : Injoinic Corp ( )
Description
The IP5306 is a multi-function power management SOC with an integrated boost converter, lithium battery charge management, and battery power indication, providing a complete power solution for mobile power supplies.
The high integration and rich features of the IP5306 make it possible to use only a few external components in the application and to effectively reduce the overall solution size and BOM cost.
Features
1. Synchronous switch charge and discharge
2. 2.4A Synchronous Boost Converter, 2.1A Synchronous Switch Charge
3. Boost efficiency up to 92%
4. Up to 91% charge efficiency
Applications
1. Mobile Power / Charging Po
2. Mobile phones, tablet PCs and other portable devices
Power control Using Key method
The IP5306 recognizes long and short key operation, and pin 5 is floating when no key is needed.
1. The key duration is longer than 50ms, but less than 2s, which is a short press action. Short press will turn on the power indicator and boost output.
2. The duration of the button is longer than 2 seconds, which means long press action. Long press will turn on or off the lighting LED.
3. The keystrokes less than 50ms will not have any response.
4. Pressing the button for two consecutive times in 1s will turn off the boost output, battery display, and lighting LED.

Re: NanoVNA does not want to start -solved
Thanks for the link, but maybe you could post the file here in the files section so we don't have to register on yet another forum?
Although this is for the IP5306, the NanoVNA uses the IP5303 and the pinout is slightly different but the specs are the same.
I tried putting a 10uF cap on the input to the 3v regulator but that didn't work - in fact, when the inverter went to sleep almost no load would wake it up.
So - I added the 10K resistor and button sw and use that to turn my unit on-off now.

Re: NanoVNA does not want to start -solved
Brian, Larry, a little correction. The 4mA consumption is with another Nano from a friend, and yes, he had an empty battery on receipt. I don't know why yet. In the meantime I have measured my unit consumption. The values are as follows:
PWR switch is OFF: 0.59 mA
PWR switch is ON, but Nano is not started: 0.64 mA
Started up with the new micro-switch :
Nano power-up: 182.8 mA
Nano goes in sleep mode (40 sec LED) set the PWR switch OFF: 3.83 mA
My values seem normal.
I do have a translated version of the IP5603, See link below.
If you want to know more about the strange behavior of the IP5303,
then we are not alone. The same problems are with a battery pack - see the M5Stack Community.
Link:.
You will also find the English translation of the IP5303 there.

Re: NanoVNA does not want to start -solved
The chip used is actually an IP5303 (per the schematic) and I too have not been able to find an English copy - you can always translate chunks of text with Google translate though.
The quiescent current is in the uA range.
As for turn on issues that I have also seen, I will be placing a 10uF cap at the input to the 3v regulator so that when switched-on, there will be a momentary current spike.
Hopefully, that will get the chip to turn on.

I am nervous when giving my card details to someone whom I don¡¯t know. Hence my preference is to use Paypal. This is not available via aliexpress I understand. Hence I turn to ebay as first choice.
My black nanovna with all the extras, usb C and lead, came from ¡°flyxy2015¡± and is ebay item 143272472926. Price was good and I received it in Cyprus in 3 weeks. I was pleased to give him 5 stars. The load shunt was within 0.1 ohm of 50 and had a manufacturer¡¯s serial number on it. (Measurement limited by my Marconi bridge).

Re: NanoVNA does not want to start -solved
Herman, your figure of 4 to 5 mA with the nanovna Off looks very high. If you assume a battery of one to two amper-hours then this will discharge in less than 2 weeks! Most users, including myself, have received our nanovna after 3 weeks in the post and found them ready to go when the switch was operated. May I suggest that you look as to why it is consuming 4-5 mA when off. (Not an easy task but look to possible wrong polarity on electrolytic capacitors as they can draw this sort of drain. With the missing current adding up to 15mW of power, it might just show up on a top grade thermal camera if you can find one with a 0.1 C resolution or better.)
I have looked for a IP5306 data sheet in English but failed to find one. Looking at a Chinese one, which language I have no ability at all, I see the figure of 50uA which may be the off current. This would mean a possible 4 years to deplete the battery. Any Chinese speaker able to confirm this, or otherwise.
Regards, Brian.

NanoVNA does not want to start.
Hi group. I received my black NanoVNA a few days ago.
This turned out not to want to start after unpacking.
I thought the battery was empty, so I connected it to the USB charger.
He wanted to start up immediately on the USB. The battery was charged very quickly.
After disconnecting the USB, I wanted to start up again, which never did not work.
He worked on the USB cable, so I worked on the USB cable all day.
My colleagues with other NanaVNAs (including the white ones) apparently also had battery problems.
On the forum in message # 639 there is mention of adding C38, but it is already there with me (see photo), and gives no solution.
The following day I did further tests, with strange results:
- I can boot with the USB cable, but not with the battery.
- after removing the USB cable, I was able to continue working on the battery for another 2 hours.
The battery was not defective, I just could not start it.
I then did some research for the following.
Once the NanaVNA runs on the battery, and then is turned OUT, the blue LED lights up for another 40 seconds. I already wondered why that is in the manual.
This means that the IP5306 controller then goes into Deep Sleep Mode.
That happens when less than 45 mA is used to save the battery.
The strange thing is that as long as the LED is on, I can start up normally with a battery.
Once the LED is off, and the IP5306 is in Sleep Mode, I cannot boot anymore.
According to the datasheet this is normal, and the IP5306 cannot be activated in sleep mode!
Unless: disconnect the battery, and back on, or at least a consumption of >45mA must be seen again, and apparently that does not work with the NanoVNA.
The battery cannot be disconnected from the Nano, which is according to the diagram directly on the IP5306. Note: if the NanoVNA is off, the battery consumption of 4 to 5 mA is still on the high side.
A consumption of >45mA is probably not yet available at start-up, so that the IP5306 does not come from sleep mode.
If you look at the diagram, the IP5306 has a pin 5 (key) that is not connected.
With this, however, you can put the controller in the normal load mode or get it out of sleep mode.
As a solution I have placed a micro push switch (glued) on connector P2 between GND and SWCLK.
On SWCLK I place a SMD resistor of 10K in series and with a wire I go to pin5 (key) of the IP5306.
In this way I can now do the following:
- I press the micro switch briefly 1x, the blue LED lights up and then I switch on the on / or switch, and see: the Nano starts up!
- I press the micro switch twice briefly, and the blue LED and the Nano go OFF again. Also switch OFF the on / off switch. This was the minor modification.
The photo of this modification can be found in the attachment.
Hopefully many have been helped with this.

Hi Franks
Any luck to have the STL Files , since I have a printer of my own
or are they on Thingiverse ?
It is a nice case

Re: NanoVNA does not want to start -solved
Thanks for the fix, Herman.
I had added the cap on the DSP reset line and it seemed to work for me but I did notice the strange way that the inverter chip worked.
I wonder if we can just do away with the power switch and add your circuit to turn the unit on and off.
Cheers
