      nice, maybe more text Instructions on the board will be better.

        Is the custom proto board working out good for you? I just received my stock Proto board and found the same limitation you did. I can’t connect any pins and use the bottom module. Do you have any extras for sale or where could I purchase it?

        Also I noticed your ADC and DAC screen printed labels are swapped compared to the core. Is that a mistake or did you swap the pins in the design?

          @m5stack 在 Custom Prototype Board 中说:

          I've just received the headers, which seem to be custom parts so they're not readily available which is a shame (and expensive since they only ship them with a module or core). Once they have been soldered I'll test them and report back - thanks for the note on DAC/ADC it's a print error the pins are the same as the main board.

          I have also had a few blank enclosures made, with the holes removed, in both PLS and ABS for testing.

          I really like the M5Stack but it's let down by not releasing more design files (for all the enclosure parts) and having better access to custom parts such as the headers so other developers can make their own modules.

            @world101 the pins and the sockets are the customization. if u want more, u can order from me(email me), i will give u nice price. i had not swapped anything, it is the same.

              Out of curiosity what package did you use to do your breakout boards? I am looking at drawing up a breakout sch/pcb in KiCad for sharing as we speak.

                I used Easy EDA which imported the pcbdoc file after some messing around with the format. I will make the gerber and pcb files files available as well as the 3D prototype enclosure file (with solid edges) soon.

                I have now tried out the new board with a couple of simple jack connectors and all seems to work!

                      This is excellent. Looks like you are doing a temperature reading (thermistor/thermocouple) setup, which is what I have been working on. Are you using a voltage divider to calculate temperature? If so, please provide your schematic.

                      Also, can you provide part numbers for the input jacks (2.5mm I assume)? I have some panel mount jacks that were for another case enclosure, but they are too big for the m5stack. Yours look great.

                      How accurate is the temperature? I've been reading the ESP32 ADC can be not quite linear and therefore not so accurate. So I was looking into another ADC breakout module like the ADS1115 for more resolution bits and accuracy.

                        Yes the device will be used to record multiple temperatures using DS18B20 sensors on one wire with a single 4.7k resistor. I hooked up 5 and can read them indiviudally since they have there own addresses. I only need the temperature to the nearest degree so they are fine for my purposes.

                        I actually use a 3.5mm jack and bought a few connectors as like you found that many do not fit, however the very small SMD mounted ones just fit in the standard case. The ones I found are on Amazon:

                          Hello, your prototype board is very usefull, more than the genuine one.

                          It's possible to order a set from EasyEDA ?

                            Yes, if you head over to https://easyeda.com/suremicro the design is there which you can use to get your own boards made. I used JLCPCB.

                              Haven't used JLCPCB, I've used Seeedstudio Fusion service https://www.seeedstudio.com/fusion_pcb.html a few times. They are especially good if you need several of the same board as they send 10 copies

                                @suremicro sorry its been a long time, but do you still have pcb/3D case somewhere ?
                                Gonna github / easyeda ... nothing found :(

                                  Hello @saiaman01

                                  don't know about the PCB, but the 3D case is here.

                                  Thanks
