This is definitely a class-D high power audio amp. Visually similar is this one. Based on TPA3116 chip. Definitive answer if you remove the heatsink and see what written on the IC.
Your question & issue is not totally clear. How exactly are you triggering your debugger to view before and after an interrupt ? By its very nature, interrupts are usually completely asynchronous - you'll have to put your debug traces inside your ISR. Right at the beginning, and just before...
I do not understand what is the purpose of the ADC ?
For your RPM input, I suggest you use an IR sensor like this one to send you pulses for every revolution. You would need to put a reflective tape piece on your bldc/ wheel. Then sense the positive edges and measure the time gap between two...
To add to the above information, here are side elevation close-up pics. I
t sure looks like a ceramic filter structure, but which one ???
Dimensions are 11mmx 7mmx 3mm
Also to add that the frequency bands are as follows i this attached table.
Note that this assembly ALSO has GPS and GNSS...
I suspect there's a mishandling of your data array indexed my 'GasIndex'
Check your array sizes vs the index used to access. Especially the case for vacuum, since this is handled differently.
Your code is too detailed for me to cross-check everything, but I suspect the error is related to the...
First time we're reading about 50-100Hz oscillation requirement. Incidentally 1000rpm translates to 16.67rps which translates to max 300 oscillations of 10deg width per second capability.
The load on the motor is obviously not due to just the 10gms+10gms of your foil & rod. Its due to the water...
This component is placed in the signal path next to a multi-band GSM antenna.
It seems to have 3 terminals - 1x GND and 2x in signal path.
I suspect it is some sort of bandpass filter, but cannot locate the exact details anywhere.
Any help ?
That is my thinking too. Though I was surprised when I calculated (using an online calculator - track width 1mm, gap width 1mm, FR4 board thickness 1mm) it came to ~73ohm, not 50ohm
My other concern is that -- Why is this particular length of transmission line even present ? Is it to make the...
You need LiPo 3S batteries of higher current capability, or try use 3SxC LiPo batteries with a higher rating.
Adding electronics is a waste of time where the battery itself can do the job.
You can get such converters for about a buck or 2. They'e available everywhere. Such huge analysis seems an overkill imho.
Here's a few :
model 1
model 2
model 3
etc
Cross posting, since the high-tech guys in RF section don't seem to have basic answers.
I have these antenna modules for GPS and multiband GSM.
The vertical bit is for GSM, but I need to reposition it due to some mechanical constraints of my enclosure.
Q1: Would it be feasible to de-solder...
