Re: Best practices for mounting a PSU5
The bottom of a PSU5 is ground, same as the original TO3 regulators. If you mount it on top of something that is not ground an isolation washer underneath is recommended but not required. If everything is clean then the solder mask will prevent shorts from occurring. The ground connection is made th...

Re: PSU5 will not power Panel64
I'm not entirely sure what a Panel64 is so I Googled it and found this https://forums.parallax.com/discussion/173346/playing-with-the-parallax-p2-panel64 and in the photo I see a couple of my power supply modules. I assume those are what you are referring too. I have no experience with those panels ...

Re: ESP32_BAT_PRO power measurements
You need to initialize all the parts on the board. There's example code on Github.https://github.com/EzSBC/ESP32_Bat_Pro/ ... pSleep.ino
You can't leave parts of the system in an unknown state and expect it to behave well.

Re: ESP32_BAT detect USB connection
I have seen this thread and some other users emailed me. There isn't a way of detecting if the USB power is present. It is an oversight in the design of the board. There's a way that will work if you are prepared to add external resistors. The Vin pin will have voltage on it only if the USB connecto...

Re: Issue with PSU5
This is new to me on the PSU5. This is a generic issue with switch mode regulators with built in current limits and I haven't seen it on the PSU5, only on the PSU3-12 and PSU3-5. The mechanism is a little hard to explain so I will provide the fix first and then try to explain what is happening. The ...

Re: ESP32_Bat_Pro and esphome
Nothing that I can think of. Thanks for publishing the code. Everything helps I'm very interested in knowing how well the remaining capacity corresponds to remaining runtime. I did some tests but its a very slow process and I would like to see some data for cases where the average current drain is l...

Re: Pin 26 ?
Next to pin 25?
Do you mean IO26? It is labeled DAC1 on the schematic.

Re: Grbl-Esp32 Big Problem
The SD card is just the card, no electronics and its wired in the same way as the original Grbl_ESP schematic. In the beginning of the code is a list of the pin numbers used. The ESP32 board works, the code works. That means its not wired up correctly or the adapter is interfering with the signals t...

Re: Grbl-Esp32 Big Problem
I will try to load the code on my board and see if I run into any issues. It is extremely unlikely that the LEDs are causing the issue you are seeing. Many people have successfully accessed microSD cards from my boards. I wired up the SD Card as per the diagram of the esp32_cnc_test_v4.1_schm.pdf I ...

Re: Newby lost getting started with ESP32_Bat_Pro
I'm going to answer in steps as I load the library on a clean install of the IDE and duplicate the process of getting the demo to compile. I will make screen captures as I go. The pinout is also OK for the Bat_Pro board. Pin 13 is the battery connection. The driver for my board is on the GitHub page...

Re: SPI on ESP32
The ESP32 is a strange device. It seems to be more flexible than it really is, in particular, it has fewer true IO pins than you may think by just looking at the pin diagram. Many pins are not truly available as IO pins. Since most ESP32s are used online I chose to compromise the pins used by the SD...

Re: Max Vin voltage
I have resolved the high input voltage issue once and for-all by adding a switch mode regulator to the ESP32 board. The board can be found here https://www.ezsbc.com/product/wifi01-sw/ It doesn't have the low standby current of the battery powered units but it works directly off car and truck power ...

Re: Start button programmable?
The USB to Serial converter is always on when there's power on the USB connector. You may have the incorrect baud rate selected. When you press the reset button you get the boot messages from the ESP32.
