The value of the device in the schematic diagram does not display the real value. Please pay attention to the text

Re, If I look at the schematic, it’s four identical filters. Where you saw that: "the schematic diagram notes that TG uses 470MHz." ?? cdt

Do you have a 470MHz SAW? I see that the schematic diagram notes that TG uses 470MHz, and I saw it at first, but later forgot it, which led me to weld 433.92 B3555

Thank you for your advice Meanwhile I watched some videos on youtube I will buy low temperature soldering paste 138°C. This will also be used for other components and future constructions.. This

I see that the last page of the datasheet has a clear description of the welding temperature The above is the temperature of the device. The actual welding equipment temperature must be slightly

hello, Can you tell me the best solution for soldering 3555 filters. Epcos. The weld appears to be from under the component. I have an iron with hot air type JCD 8898. Can you give me the best

Yes, I think the encoder's pluses and points may be related. For example, the trigger edge is currently triggered at the rising edge. If it is set to edge trigger, it will be twice the relationship. I

Brilliant!? So now you have your "fun of DIY" mood back! Well done. I have dissected a dead mouse this evening, extracted the encoder, connected it up to my old prototype board and experienced the

Succeeded. Change the 789 line of simpleSA.ino to encoder. attachSingleEdge (ENC_B, ENC_A); In the middle of the night, it was so simple, ha ha

Before I selected the encoder, I read the datasheet of EVQWK that you designed and selected. It is a mechanical encoder that provides quadrature pulses. Therefore, I selected the mouse encoder

The number of pulses per revolution should not matter. The encoder I use has a mechanical click for each step, one complete 360 revolution would result in 15 steps. Think of the scroll wheel on your

At present, the basic functions can be used, except for the TG function, I still don't know how to use it; In addition, I disassembled a mouse and used the encoder inside the jumper, and found that it

The oven I used made a simple soldering furnace for DIY soldering. Accurately requires the PID algorithm to control the temperature curve. Sometimes I simply turn on the power. After 2 minutes, I see

Finally succeeded, the problem lies in the PIN1 pin of the active crystal oscillator, the datasheet is defined as Tri-state, the test screenshot has a switch for grounding, I have encountered it

I see you have found Si Labs AN417 describing the requirements for external oscillator, which I had not looked at before. I think the best approach would to use an oscilloscope and a low capacitance

Oops - the settings.html, help.html and backupRestore.html files are a hang over from another completely different project (I used some of it as the base for some of the wifi code) and can/should be

Hello, I received the PCB's from JLCPCB. Again the PCB's are superb, nice work. These are the most small PCB's? I’ve ever made by JLCPCB. I’ve had them for about ten days and I always wonder how

I don't understand what the Reverse Beacon Network is?

When I was calibrating, I found that I had wrongly connected the crystal oscillator(OT322530MJBA4SL). The correct one should be connected in series with the DC coupling capacitor before inputting to

Of course, if you are interested, I will check my design and share it after confirming that there are no obvious mistakes; I do not use TCXO. TXCO is not easy to buy. I checked that LCSCs are out of
