Lookdown2 not working!

The HIH-4000 Humidity Sensors has an output voltage which must be referenced to percent humidity. My DS2438 is reading the voltage output of the humidity sensor. I then need to use a lookdown table...

Re: HC-05 Bluetooth

I found out the hard way that not all HC-05 modules work the same. Use the version AT command and look for modules with the latest firmware versions. Try to establish a serial communication first...

Re: PWM, H-Bridge and NCO - PIC16F18446

The new one is the BTN8982 and is only produced at TO263-7 package.

How do you solder this one on the PCB by hand?

Anyway, have ordered the board that you showed. Hope it is an old stock and...

Re: PWM, H-Bridge and NCO - PIC16F18446

You are right regarding the unknown chinese parts.

I tried to find the specific chip but seems it is too old and stopped production by Infineon.

Maybe they produce other, newer chips now. Have...

Re: PWM, H-Bridge and NCO - PIC16F18446

just a thought too..... it is a lot of technology for the price, but sometimes these types of things, probably from China don't meet expectations.... but sometimes they are good!!!

Re: PWM, H-Bridge and NCO - PIC16F18446

Wow!!! Amazing module! 40amps DC at 85 degrees? Can't believe it!

Many thanks for this.

Re: PWM, H-Bridge and NCO - PIC16F18446

there are a bunch of these types of things with your I and V range. Thats why I was wondering if your voltage was like 200+ volts or 50-80 amps.

Re: PWM, H-Bridge and NCO - PIC16F18446

It will be between 20-25 Volts.

Load max 10-12Amps.

At low pusling frequencies, obviously the 19mH coil will be more like a low ohm resistor, so the current will be limited.
