  Felix, you were correct. All that was required was a cross-over of the white and yellow leads in the cable. Thanks. ...Brian

  @felmue You are right, it seems to be a voltage mismatch. The UART requests 5V, but ESP32 delivers only 3.3V. Reading: "On-board level shifter, Standard 5V TTL for I2C and UART, 3.3V TTL SPI" Find more: https://manuals.plus/elechouse/pn532-nfc-rfid-module-manual#introduction Time to buy a M5stack reader unit and use the standard UiFlow drivers. Thanks!

  Stamp Pico won't connect to UIFlow

  I think I probably have a defective unit. I have tried with only a single tab open, latest version of Google Chrome, tried it incognito mode also just to be sure some extension wasn't getting in the way. Despite all efforts it never connects to UIFlow. I know it's on the network because my router is showing it connected and sending/receiving some packets. I will probably stick with devices that have USB-C on them, this is way too much hassle and I don't want to have to rig up a programmer just to toy around with a prototyping device. Oh well, at least I'm only out $5.

  Hi Felix, thank you for your fast reply. I've used different Atmega, Attiny and STM32 based boards in the past, but new to ESP32. That's the reason for my "stupid" question. ;-) Thanks again.

  @srmobar said in Just a single M5Stack Plus-Module and no idea what to do: @ajb2k3 Thanks! Looking forward to additional tipps. My goal would be, to not require a core but to find a way to interact with it another way. If this is not possible, I concede :) I'm keen to try out different things and be it just for the sake of trying it. Can't be bad to learn a thing or two along the way While it’s designed for ‘Tara know, your not limited to M5Stack. You just need to understand the pin outs and communication method

  Hello @IndianaTux does that work with real loads (and not just the multimeter) attached to the output? I am asking because it looks like the MOSFET keeps conducting after M5.shudown() is called and only putting ESP32 into deep sleep (and by doing so reducing the current) makes the MOSFET to finally open. If my thinking is correct a real load on the output would keep the current high and thus the MOSFET closed. (I hope I am wrong.) Thanks Felix

  I'm sorry, the sample works! The problem was that the RFID2 return a different chip ID and takes longer to initialize, and my microBlocks library didn't expect that. Thanks for your fast response.

  Multiple M020 USB modules stacked?

  Hello @cyberluke not without hardware modification, I think. While SPI uses some signals (SCK, MISO, MOSI) in parallel for all SPI slaves, there is one signal for each SPI slave so it can be selected. In other words if you stack multiple M020 USB modules (w/o hardware modification) all of them would share the same select signal and therefore react at the same time (which is not what you want.) Thanks Felix

  Hi, I am experiencing the exact same problem. Two of the devices giving me this issue for a while now. I have no idea how to resolve.

  Hello @Veto6017 thank you for reporting back - this is quite interesting. I used AT+COPS=1,2,"22802",2 to manually select UTRAN (2) instead of EUTRAN (7). Note: "22802" is provider Sunrise in Switzerland. BTW: AT+COPS=0 gets you back to automatic selection. Thanks Felix

  Hi Lukas, Even I'm trying to interface ADS1256 ADC with Stamp PICO using SPI protocol but it is not working and I'm not able to read any data in arduino IDE. I cross-checked all connections and seems to be OK. Any advice on this problem.

  Thanks @felmue , I did notice that too so I used continuity tester to see if andy of the RS-485 terminal screws were directly connected to the header pins that connect to the Atom's 33/23 pins I did't detect any continuity. I want to connect a Nextion Display that uses a Serial connection to the Atom Switch and was hoping to utilize Pins 33/23. I'm thinking I may need to purchase something like the MAX485 RS-485 module to attach to the Nextion display and run my serial connection over this RS-485 connection. Think I have some reading to do. ;)

  Hello @solders-soul_0z from what I understand the GPS module only supports one antenna at the time connected to the connector labelled IPEX. It looks to me that currently the internal antenna is connected (gray cable). Have you tried to switch and connect the external antenna (black cable) instead? Thanks Felix
