  tnks a lot !!!! this sketch is working for me #include <M5UnitOLED.h> M5UnitOLED display ( 26, 32, 400000 ); // SDA, SCL, FREQ M5Canvas canvas(&display); static constexpr char text[] = "Hello world ! こんにちは世界！ this is long long string sample. 寿限無、寿限無、五劫の擦り切れ、海砂利水魚の、水行末・雲来末・風来末、喰う寝る処に住む処、藪ら柑子の藪柑子、パイポ・パイポ・パイポのシューリンガン、シューリンガンのグーリンダイ、グーリンダイのポンポコピーのポンポコナの、長久命の長助"; static constexpr size_t textlen = sizeof(text) / sizeof(text[0]); int textpos = 0; int scrollstep = 2; void setup(void) { display.begin(); if (display.width() < display.height()) { display.setRotation(display.getRotation() ^ 1); } canvas.setColorDepth(1); // mono color canvas.setFont(&fonts::lgfxJapanMinchoP_32); canvas.setTextWrap(false); canvas.setTextSize(2); canvas.createSprite(display.width() + 64, 72); } void loop(void) { int32_t cursor_x = canvas.getCursorX() - scrollstep; if (cursor_x <= 0) { textpos = 0; cursor_x = display.width(); } canvas.setCursor(cursor_x, 0); canvas.scroll(-scrollstep, 0); while (textpos < textlen && cursor_x <= display.width()) { canvas.print(text[textpos++]); cursor_x = canvas.getCursorX(); } display.waitDisplay(); canvas.pushSprite(&display, 0, (display.height() - canvas.height()) >> 1); }

  @brunz It seems that the power lines of motor and servo ports are directly connected to the battery. So voltage is ~3.3 - 4.2 V.

  The problem is finding the atom lite schematic. It is not clear what voltage stabilizer was used. I suspect it has a voltage drop between input and output of ~1.0-1.2V. I connected a li-po cell (4.2V 900mAh) directly into the 5V input. I measured the cell voltage and sent the data to the local blynk server every 20 seconds. Additionally, I measured the internal temperature of the esp32 chip and it oscillated at a constant 50-51°C. With this connection the chip worked for about 6.5 hours and then turned off or stopped working properly at 3.41±0.1V cell voltage. So the esp32 chip probably stopped working at ~2.2-2.4V on a 3.3V supply line. I don't know how usb-uart converter will work with supply voltage lower than 5V. A colleague from "Esp Poland" forum tested power supply for ws2812 diode and at 3.9V the diode went crazy. Screenshot from blynk contain: cell coltage esp32 internalge temperature atom lite uptime/working time

  ATOM HUB AC/DC, RS-485 VOLTAGE CONVERTER, VOLTAGE PROBLEM

  @kine90 said in ATOM HUB AC/DC, RS-485 VOLTAGE CONVERTER, VOLTAGE PROBLEM: I am working on a project where the switch is controlled by the M5 PIR SENSOR. When I power the ATOM from USB everything works fine, when I power it with a 12V 3A PSU thought the RS485 voltage converter the PIR begins malfunctioning (fake triggers). I checked the voltage of the two groove outputs (from the hub and from the atom lite) under USB and 12V power. As long as USB is connected, the interfaces shows a quite stable 4.98V. When the USB is unplugged, leaving only the 12V power source, the voltage drops to 3.3-3.28V, if the atom is removed it goes back to 5V I guess this is causing the PIR to misbehave, since it requires 5V. What´s wrong? According to labels on the components and to the HUB schematics, I expect 5V 2A from the DC/DC converter. Based on your photo's you haven't connected the 12V to the correct pins of the RS485 connection. 12V needs to be connected to the RS485's red and black pins.

  Have you tried the "Cold boot" method i posted in the forum? windows has a preinstalled driver that breaks the current driver requiring a very specific method to remove and install.

  Lobo Micropython is out of date. You need the 1.7.7 firmware that is available in the M5Burner firmware installer found on m5stacks download page.

  Hello @mviewlab yes, they are just GPIO pins. Please checkout the pinmap here. Thanks Felix

  Hello guys from the schematic there should be no difference whether you power M5Atom via 5V on the Groove connector or the 5 V pin in the back. Measuring for continuity between Groove and the respective pins in the back also shows they are connected 1:1 and are the same. Running a simple sketch on my M5Atom Matrix, which only connects WiFi and is showing that by changing the LEDs from red to green, I see that working ok with voltages from 2.8 V to 5.2 V. BTW: I am getting the same results with an M5Atom Lite. Thanks Felix

  @felmue Tried both. 3.3V has a bit higher current. Strange, if there's just an LDO (guessing - no schematics!). Also removed IR and RGB LEDs. Tried with Arduino and Espressif IDF deep-sleep example. No success. NodeMCU with Wroom32 is kind of OK (1.6mA), by the way. But mechanically too large ...

  Hello, how long you've had the module? it does sound like the battery have been worn out. have you been leaving it away for quite some time? this could be one of the reasons.

  Hello @alien on the M5Atom there are no predefined pins assigned to RX2 and TX2. GPIO21 and GPIO25 are assigned to I2C so I would not use those. I have successfully tried GPIO19 for RX2 and GPIO22 for TX2. Good luck! Felix
