Re: Voltage Error on OUT1000

Hi, the errors only occur between 3.07V nd 4.1V, by the way. This is the circuit i built: https://up.picr.de/32741077aq.jpg And everything soldered together: https://up.picr.de/35422644va.jpeg The one 10kOhm resistor at the bottom was added afterwards, because of the 100nF capacitor before the ATtin...

Voltage Error on OUT1000

Hi all, i've made a simple circuit to control a pc fan. The circuit is based on an ATtiny85, which measures the voltage on its Pin3 and then sends a corresponding pwm signal to the fan. https://up.picr.de/35387100lh.jpg I control the voltage on Pin3 via an OUT1000, where 0V is OFF and 4.2V equals 10...

Using a capacitive soil moisture sensor with VINT-Hub

Hi all, just wondering if it is possible to use an anolog capacitive soil moisture sensor directly connected to the VINT-Hub? :?: I'm think of a sensor like the dfrobot SKU:SEN0193 https://www.dfrobot.com/wiki/index.php/Capacitive_Soil_Moisture_Sensor_SKU:SEN0193 It is powered by 3.3-5.5V and output...

Re: Control 4-pin 12V DC fan via DCC1001_0

Hi,
if you're going for a PWM fan, have a look at my GIT repository :)
I got this working very well using the OUT1000 and a self-designed simple circuit powered by an ATtiny85.

Re: Control 4-pin 12V DC fan via DCC1001_0

I'll go for the OUT1100 and will report :)
The fan's specs say, it supports a frequency starting @ 18KHz...

One last question:
As the fan will be powered by an external 12V psu, i need to connect the GND of the OUT1100 to the GND of the fan to get this working, right?

Regards

Philipp

Re: Control 4-pin 12V DC fan via DCC1001_0

Could the OUT1100 be a solution to this problem? It's PWM signal is 5V @ 16KHz.

What does "PWM frequency max: 50KHz" mean in the HUB0000s specs?

Re: Control 4-pin 12V DC fan via DCC1001_0

Hi Patrick, thanks for your answer. But doesn't the HUB0000 send PWM-Signals @ 16KHz? Wouldn't that be a problem, since the Intel specs for pwm-controlled fans say: 2.1.4 PWM Control Input Signal The following requirements are measured at the PWM (control) pin of the fan cable connector see Figure 7...

Control 4-pin 12V DC fan via DCC1001_0

Hi all, i've got some general questions regarding the DCC1001_0 and DC computer fans. i'd like to control a 4-pin 12V DC fan using the DCC1001_0. In fact it is a Noctua NF A14 industrialPPC-3000 PWM fan. The fan has a 4-pin connector for VCC, GND, PWM (0-5V @ 25KHz) and RPM. Is it possible to contro...
