I did search on Digikey. ribbon cable, flat cable connectors. I have no luck to find the right connector for this LCD module.
The pitch for the cable is 0.5mm. By looking at the module, it looks like need some connector can allow cable plug into it and solder other end to PCB.
What kind of...
I am selecting LCD module for my project. However, I found some module: 96x64graphic, 84x24graphic, 8char x 2row. However, those module requires supply current 180uA above. In my project, the maximum average current is only 80uA. Is any LCD module only drive tens uA and also have 8char with...
There is no shielding. The sensor need to be exposed to outside in order to sense harmful gas
So, a low pass filter at the input of the circuit, you mean the input of power? It has decoupling cap
Thank you
Hi all,
Basically, I designed the circuit which using a chemical sensor to detect harmful gas. The circuit is working fine. However, when I use walkie talkie to simulate RFI and test the circuit response, it has big problem. When the walkie talkie is toggled (on/off), the sensor output shoot up...
I made a project which will filter out unwanted frequencies. I applied FFT to the signal and multiplied with window function in frequency domain. and do the IFFT. it should reconstruct the original signal with applied windowing. however, the output has been reconstructed, but i always can hear...
basicly, we are using two mics. the first one mic will be placed as close as possible to the human mouth, which is for voice signal picking up(there will be some background noise mixed with voice for sure). the second mic is using for picking up the background noise. and then we can 180 shift of...
I am going to design a project which will cancel the ambient noise. the device will capture the speaker's voice but eliminate all other noises from ambient such as high way, construction field, in airplane, etc..
I did some researches, the two microphones seems right direction. the first mic...
our prototype can only pinging through hub. it wont work on switch. we use the same network cable, same condition. when pinging through hub, it works very well; when connect it to the switch directly, it stops pinging. Why? What is the potential problem?
Please anyone has an idea.
Thanks in...
