hey guys :) for me this 1kOhm pullup definitive work, I connected the ESP8266 today and it worked straight away! I have an 10m line on the controller then a Stub of 2m with 1x sensor, then 20m line down in the ground. @seb82 I also tested with a 100nf capacitor and a 100uf, but that didn't work for ...

Hello A few months ago I made a couple of ESP8266 boards (Looky Wifi), many times I had problems with the DS18B20 Sensors. :evil: Now i have a Project where a DS18B20 Sensor is 20 Meters Deep in the Ground, the Reading of this sensor was not possible, i got only Read errors. :oops: At home I connect...

I tested the digital input, wanted to know how high the frequency can be measured. https://youtu.be/kLDFesXSjzo Tested on: ESP_Easy_mega_20210114_test_beta_ESP8266_4M1M 10 Active Tasks! 300 HZ it works fine 500 HZ it works, but signal begining to distortion 800 HZ still works 999 HZ still works :) T...

OK the RS485 will never work, theMAX485CSA+T Needs 5V Power but on the board, the chip is only powered with 3.3v

But no problem in the next version i will use MAX3485ESA+

I've ordered a couple of MAX3485ESA+ and will test them on breadboard.

If i swap the Serial in Software, can i use the GPIO1 and GPIO3 for other Functions? Mabe to Control Relay? or as a Input?

oh man, I totaly screwed up that
i never noticed that there are a second Serial port.

Yes, GPIO 15 Control "Relay1" or RS485 "RE" and "DE", you can select this via Jumper.

One of the "hardware" bugs is that I connected the TX RX form ESP8266 directly to the RS485 Chip, so you canot flash de ESP if it is in the circuit.

Nope, only the one Digital Input is isolated.

really at the last moment i integrated the rs485 chip in the circuit diagram. I think the circuit should be sufficient to read an electricity meter. but i haven't tried it yet.

Hi TD-er, This is the Link of the Enclosure (95x90x40mm) https://www.aliexpress.com/item/32972146250.html?spm=a2g0o.productlist.0.0.440a523dwM82kf&algo_pvid=ba1b5b7f-c107-4d82-a2e2-880b071c9f0b&algo_expid=ba1b5b7f-c107-4d82-a2e2-880b071c9f0b-0&btsid=0bb0624516121171542621627e506e&ws_...

Hi folks, after 2 years of development, i have finished my ESPeasy Hardware project and yes i don't worked permanently on this project. :D Looky L Wifi V8 Assembled.jpg Looky L Wifi V8 Enclosure.jpg The goal was a PCB with terminals to connect the DS18B20 sensors and everything should fit in a cheap...
