ESP32 / ESP32-POE-ISO
Last post by bailey@comcap.net - June 12, 2025, 10:09:24 AMI am using an ESP32-POE-ISO running OLIMEX_ESP32_POE-20241129-v1.24.1.bin.
I'm not entirely sure if you guys maintain the MicroPython binary?
I'm having trouble using sockets - specifically I am trying to mark the packets with TOS/DSCP QoS settings. It doesn't look like the binary currently supports this?
Would it be possible to enable the socket options specifically TOS?
Thanks,
Bailey

A20 / Re: OLinuXimo A20 LIME2 : use ...
Last post by LubOlimex - June 11, 2025, 08:11:21 AMThere are a few options:
1) You can use the LIME2-SHIELD:
https://www.olimex.com/Products/OLinuXino/A20/LIME2-SHIELD/open-source-hardware
2) You can get one or more A20-OLinuXino-LIME2-UEXT adapter(s) - this adapts 0.05" LIME pins of the GPIO/LCD connectors to breadboard-friendly 0.1" step connectors. Notice that it comes WITHOUT CABLES!!!

Cables:

https://www.olimex.com/Products/Components/Cables/Ribbon/CABLE-IDC40-15cm/
3) You can purchase matching female connectors FEMALE-YAV36P-2x20. This will still require soldering at the female connectors but your board will be safe:

A20 / OLinuXimo A20 LIME2 : use GPIO
Last post by abriotde - June 10, 2025, 07:02:25 PMI have an OLinuXimo-A20-LIME2 card PC. I would like to use GPIO but I don't understand how could I physically connect them. In the manual, all GPIO are listed. I know with one to use, but male pins on the card are to thin for standard jumper wires (https://www.olimex.com/Products/Breadboarding/JUMPER-WIRES/JW-200x40-FM/). I can solder it, it's to thin...

Last post by Volker - June 09, 2025, 07:24:59 PM<comparison and evaluation of similar products is part of the engineering process>
It is also part of the engineering process to decide if a project is a waste of time and resources or not.
See, we did put a lot of time into this project.
1. It took a lot of time to find out that the onboard debugger interface is no more working. https://www.olimex.com/forum/index.php?topic=9750.0
2. It took a lot of time to find out that the firmware of the module does not receive (or handle) the joined message properly.
3. We also found that the peripheral chip for the sensors is not initialized properly. One has to reset the chip after power-on to get it running.
This is why we give up. It is more efficient to use another module with less buggy software as a starting point.

Last post by LubOlimex - June 09, 2025, 09:25:07 AMDemos were just uploaded, you can find them in the GitHub sub-folder:
https://github.com/OLIMEX/ESP32-P4-DevKit/tree/main/SOFTWARE/Demo_Examples
I've added also RPi drivers for the LCD at its page.
> I am planning to use another display based on the same ST7701S driver in the future.
The code might not work with another display, even if the driver is the same. Some LCD initializing routine is vendor-specific and provided by the vendor. Check line 205-206 from the main code:
"static const st7701_lcd_init_cmd_t lcd_init_cmds[] = {..."
The initialization code was taken from the drivers for the LCD.

ESP32 / Re: POE powered relays
Last post by LubOlimex - June 04, 2025, 08:12:13 AMESP32-POE can't power MOD-IO2 sufficiently - MOD-IO2 requires 12V DC and ESP32-POE doesn't have 12V DC output.
Consider using ESP32-POE2 instead which has 12V DC output:
https://www.olimex.com/Products/IoT/ESP32/ESP32-POE2/open-source-hardware
You would also need a cable like this between the 12V DC output and the power jack of MOD-IO2:
