  @dumitru, See https://docs.m5stack.com/en/product_i2c_addr I think you might have a clash either way: Depending on chip, ENV III (QMP6988) with PaHUB: Or ENVIII (SHT30) and the cradle base with the SHT30 in it. https://shop.m5stack.com/products/btc-standing-base-for-m5-core-with-sht30 "Once M5Stack Core has been attached to BTC, it can not connect to an ENV Unit. This is to avoid I2C address conflict with built-in SHT30 sensor of BTC Base." ENV III UNIT 0x44(SHT30) 0x70(QMP6988) PM2.5 0x40(SHT20) DLight UNIT 0x23(BH1750FVI) M5Core 0x75(IP5306) 0x68(MPU6886) 0x6C(SH200Q) 0x10(BMM150) PaHUB UNIT 0x70(TCA9548A) PaHUB2 UNIT 0x70(PCA9548AP) You can confirm chip on ENV III from the sticker on the back. If conflict is with SHT30, try with Core out of the cradle.

  @ajb2k3 said in Cheap camera module for M5Stack Atom Matrix: https://shop.m5stack.com/collections/m5-unit/products/unit-cam-wi-fi-camera-diy-kit-ov2640 I was not able to have my Atom Matrix interact with the OV2640 Unit Cam... @Exie were you able to connect your Atom Matrix with the Unit Cam and have the Matrix retrieve the Unit Cam output?

  @gavin67890 I was able to get it working with 32/33 just by assigning with uart1 = machine.UART(1, tx=32, rx=33) which it looks like is the same the guy did in the video

  Hello @DanK actually there is an AMS1117 version with exactly the output voltage you measured: 2.85 V - coincidence? From the AMS1117 datasheet - feature list: Three Terminal Adjustable or Fixed Voltages* 1.5V, 1.8V, 2.5V, 2.85V, 3.3V and 5.0V But yes, the input voltage is probably on the low side. Thanks Felix

  So, the 4.6V is consistent with the schematic for the Stamp-S3, I see. The EN is connected to VIN, not VCC, via a diode, which drops it a little below the 5V from USB. This is different from the Stamp-C3, but I guess that's fine.

  Stamp-S3 randomly starts drawing 500mA.

  @bram The EN is the Reset input and is pulled up normally, and brought down to reset the ESP. While it does seem odd that it is 5V, mine does the same thing! My (ahem) LilyGO T-Display S3 Reset pin is at 3.3, which makes more sense. -Terry

  Hello @H-Gruber below code works for me using M5Stack Basic or Fire (running UIFlow firmware 1.12.3): from m5stack import * from m5ui import * from uiflow import * import module setScreenColor(0x222222) lan = module.get(module.LANBASE) label0 = M5TextBox(21, 24, "label0", lcd.FONT_Default, 0xFFFFFF, rotate=0) label1 = M5TextBox(22, 58, "label1", lcd.FONT_Default, 0xFFFFFF, rotate=0) label0.setText('Hello 1') lan.tcp_udp_config('192.168.144.1', 4711, 1, 2) label0.setText('Hello 2') label1.setText(str(lan.get_if_config())) lan.tcp_send_packet('1234') label0.setText('Hello 3') lan.socket_close() label0.setText('Hello 4') Thanks Felix

  Hello @Hnerik-Schmidt correct. I know it is a bit confusing. Most (if not all) modules have their GPIOs labelled for M5Stack (Core) and need some 'translation' when used with M5Core2 (Core2) or M5CoreS3 (CoreS3). Note: M5Core2 (Core2) has internal PSRAM and while most ESP32 GPIOs can be reassigned for various functions, PSRAM can only be used with GPIO16 / 17. That is the reason M5Stack engineers replaced them with GPIO13 / 14 on the M5Stack bus. Thanks Felix

  Has anyone had success with MicroPython SD card access on the CoreInk? I just installed the firmware that seems to be about 1 week old, but all I get is different error messages when trying to mount the SD card. With slot 1 or 2, I get: E (8624) sdmmc_common: sdmmc_init_OCR: send_op_cond(1) returned 0x107 With slot 2, I get: E (8049) spi_master: spi_bus_add_device(373): host not initialized E (8052) sdmmc_io: sdmmc_io_reset: unexpected return: 0x102 With slot 3, I only get OSError(16,), without additional info. If anyone has gotten the SD card to work on the CoreInk, which slot and pins do you use? Is there any other initialization necessary? -- Correction: it seems the only reason I get different error message is because I commented out sd.info(). With sd.info(), I still get the original error. So still no SD card support at all?

  Hi @teastain, Cool, thanks. I went ahead and ordered at risk JST XH 2-pin from Adafruit, 2.5mm seems spot on for the connectors of GoPlus2. http://adafru.it/4872
