Esp-12F programming board

Regarding the ESP-12F spawning device, the big guys have made many forms. However, due to personal reasons, breaking off the test ring always failed, and it failed too many times (I apologize to you), so I This gave birth to this strange method.

The required materials are very simple, which is a basic burning needle, either P50 or P100 (it can be tested personally); so P75 should also be possible (guess); of course, the most suitable one here is P50, because it is thin enough; However, there is also a certain problem, that is, the length is not easy to control;

If it is just the most basic programming program, then you only need 8P. If you need to use other pin functions, you will need 16P. I just want to test whether the board can be used, so it is the lowest configuration.

This is the welding effect of P50; it is easy to distort the welding

The one below is P100; it looks silly.

It should be noted here that the position of the needle tip cannot be too far inside, otherwise the chip will not fit in; it cannot be too far outside, otherwise it will not be clamped. You can use the most basic mathematics to calculate the relationship between the lengths;

Next is the effect of clamping the board in. P100 is still more reliable.

Because I only considered P50 when I was dressing up, I didn’t expect that P100 pins could also be used, so I had to do some tricks on multiple boards to use P100 pin headers.

First of all, since the length and diameter of the needle have become larger, the original position of the original component will be blocked, so the original pad must be shielded to avoid short circuit, and the pad of the soldering probe must also be covered to avoid The pin header is welded shut, so I used high-temperature tape here, and it worked pretty well! ! !

The last step is to deal with the displaced resistor flying wires. Currently, I don’t have a direct plug-in resistor on hand. Flying patches is a nightmare for me. I can only wait for the resistor to arrive before continuing. What I can confirm at the moment is that P50 can be downloaded; P100 is not short-circuited. Phenomenon occurs

One last look at the close shot

I found the plug-in resistor and the verification was successful! ! !
