  Hello @teastain your example looks fine to me. Nicely done. Regarding submission: you can create a pull-request for yourself, inside the M5Stack repository, which adds your example and M5Stack engineers eventually will check it out. Thanks Felix

  Hello @Kombistack from what I can tell the damage isn't that severe. According to the schematic those two components are capacitors. I don't think they are critical for the overall functionality of the M5Core2, they might have an influence on the performance of the IMU though. That said, you should be able to resolder those with a small soldering iron. Or find someone who can fix it for you. I don't know if this board can be purchased separately as spare part. Have you checked with M5Stack support? Thanks Felix

  Hello, I begin with this RFID UHF reader (U107), and i encountered the same issue to solve, i.e. to optimize the read distance when "Europe work location" is selected. The patch antenna within the U107 seems fitted to 900MHz band, and as this antenna is very small therefore the bandwith is really narrow. The read performance at 868MHz are then degraded. The solution I found is to modify the patch antenna like this: you have to remove the box to access the top of the patch antenna, and you have to remove the white adhesive protective sheet and stick in place a square of aluminiun adhesive tape above/againts the roof of the integrated patch antenna. The size of about 30mm by 30mm seems close to the best ... but you can try other sizes and see. You can also try cropping the opposite angle along the diagonal passing between the two feed points (not a lot !). Best regards, Thierry

  Hello @ajb2k3 I've just checked. Above blocks work for me with an M5Core2 as well. Instead of TX=17 / RX=16 I use TX=14 / RX=13. That said I do not have the RS485 unit so I am using the little RS485 board (which came with the LAN module) albeit outside the LAN module connected via a BUS module. The ACSSR is powered from an external 12 V power supply. The little RS485 board is powered with 5 V from the M5Core2. There are only two wires between the ACSSR and the little RS485 board: A <-> A and B <-> B. I also added an 120 Ohm resistor between A and B of the little RS485 board. The ACSSR already has that resistor in place internally. Thanks Felix

  The core functions maybe but mine is yet to be shipped to me yet to test.

  Hi Vielen Dank für die Antwort bin mittlerweile einen Schritt weiter. Aber sobald ich den Button drücke kommt jetzt zuerst ein A und danach tauchen lauter 255 auf und der Drucker druckt lauter Chinesische Zeichen.
