  Continuing my tale-of-woe about the PaHub: I have now tried using G0 and G26 (StickC) to connect as custom I2C to PaHUB with the ENV III attached, which works on Port A. Via the PaHUB using the top hat pins (the pins an I2C hat uses). I get "Pahub unit maybe not connect", fine on Port A.

  Looks like the upcoming "ENV PRO" is going to have the new BME668 sensor, which is awesome. https://twitter.com/M5Stack/status/1696380881513107502 https://www.bosch-sensortec.com/products/environmental-sensors/gas-sensors/bme688/ Im not sure how much the "first gas sensor with AI" thing is just marketing, but the specs and potential on the sensor are impressive. I hope M5stack supports the full thing (with its AI training capabilities) "The gas sensor can detect Volatile Organic Compounds (VOCs), volatile sulfur compounds (VSCs) and other gases such as carbon monoxide and hydrogen in the part per billion (ppb) range. Additionally to all features of the BME680, the BME688 has a gas scanner function. In standard configuration, the presence of VSCs is being detected as indicator for e.g. bacteria growth. And the gas scanner can be customized with respect to sensitivity, selectivity, data rate and power consumption as well. The BME AI-Studio tool enables customers to train the BME688 gas scanner on their specific application, like in home appliances, IoT products or Smart Home."

  I managed to get the Arduino UI running with the CORE2 (using the M5Unified 0.1.9 and the Sensirion I2C SCD4X 0.4.4 libraries). I took the example ino file and modified the header to use M5Unified.h instead of M5stack.h... and the problem seems to be there as well. The first call to scd4x.stopPeriodicMeasurement() returns an error saying: Error writing to I2C bus. Then it hangs apparently on the subsequent scd4x.startPeriodicMeasurement() call, for what I can say.

  Any chance m5stack releases FW code for individual units like this one? I couldnt find any in github. I have a few decades of experience with RFID firmware, writing ISO15693 anti-collision algorithms, etc and could add some enhancements to it for multi-tag, EAC alarms, etc. (My previous username here was in fact ISO15693) Otherwise Im going to need to use non-m5stack rfid HW for my project I think.

  @pandian-nano Thank you. I have read through that several times and it makes no more sense than the time before. I'll eventually come across something that I understand and it will sink in. Thanks again.

  I did not find any, however there is some example arduino code here: https://github.com/m5stack/M5Stack/blob/master/examples/Unit/RF433/RF433.ino Not very amateur friendly if you want to use that though.

  If you let the kids watch you disassemble and check the impellers you might inspire a future HW engineer instead of a future SW engineer. So be careful and dont do that :)

  @mrburns42, I can't help with the datasheet, I too failed to locate it. But what I did manage to find is a library for a similar sensor, which allowed me to use the M5Stack ultrasonic sensor on I2C connected to a Micro:bit (with 5V carrier board and 3v3 to SCL and SDA). If you have look at the repo below there is a little more info on the address, byte size and data type and more, see SR04_I2C.ts file, which worked for me. Sensor details: https://www.sgbotic.com/index.php?dispatch=products.view&product_id=3028#:~:text=Instead of the common GPIO,easy method of distance measurement. Associated Git repo: https://github.com/SGBotic/pxt-SGBotic-SR04-I2C
