ESP-07S

Oops, sorry. I did search but did not get a hit.

Thank you once again for your work and guidance.

I have used DB25 for many projects over the years and your answer lies in the QUALITY of the connector.

Basically the cheap chinese connectors are not much good for more than half an amp once you have scraped off the vapor thin gold plating. Insert connector say 10 times and hey presto, no more good contact !

Even the name brands have dropped their quality so unless you source genuine known quality you will have some degree of trouble i.e. Your thermistor readings go noisey.

A good connector pin is OK up to a couple of amps but keep in mind the stepper generates high current spikes so you usually need a better sized pin than the DB series of connectors provide.

Hi,

I want to swap the ESP-12 module for an ESP-07 module.

Why? I want to have an external antenna connection so I can shield the electronics enclosure area.

The 07 module has an external connector so my interest is more about updating the firmware so this hardware is usable on the Duet.

Can this be done easily?

So how does the ESP 07 or 12 module get Duet flashed?

I was planning on upgrading my 0.6 board to WiFi by wiring in an Arduino ESP8266 (ESP-07 for external antenna use). I had presumed that the Duet code would update the firmware but from your comment that seems not to be the case?

What would be the issue flashing Duet firmware to the module?
