  They actually operate on the same register, this block is used to operate independent wheels, there may be some translatione problems ( use pulse less accurate ). The parameter range is -127 to +127. we will update it later, thank you feedback.

  Thanks @felmue, I have now got the card powered by following your observations : connecting 5v to VIN, GND to GND, TX to RXD, RX to TXD I don't need to trigger PWK to get the modem operational. The modem don't connect to the network, but that's another problem..

  In my railway project I use 12V in but only get 5V out max 0xff stops the motors. Wire.write((speed >> 8)&0x80); Needs to be Wire.write((speed >> 8)&0x00); for the second channel.

  Hi @felmue, Yes, I mean that module. I will look into the documentation you provided, thank you. Regarding the number of servos I mandated the student - i teach art students - to scale down from his initial proposal of 24 servos, because of the logistics implied. He came to the class, proposing 13 servos with this module arguing that it should work, so here we are, trying to make it work. Thank you for your time.

  Hello @Thomasx sorry, I meant this blue one - which is stackable (it's also EOL though). But if yours is black then guess you have the COMX LoraWAN. Thanks Felix

  @felmue said in M5Stamp C3 programming examples: Hello @ajb2k3 What worked for me on macOS Big Sur 11.5.2 is using the ESP32C3 built-in USB via GPIO18 and GPIO19. What also worked for me on macOS Big Sur 11.5.2 was downloading and installing this driver CH9102_VCP_SER_MacOS from here. After a reboot and plugging in M5StampC3 via USB this port show up /dev/cu.wchusbserial... (in addition to /dev/cu.usbmodem... which did not work). Thanks Felix Hello Felix read here for a possible solution.

  Compatibility of IoT Base with CAT-M Module (SIM7080G) with M5Stack Core2 ESP32 IoT Development Kit for AWS IoT EduKit

  Hello @NilZ Note: I do not own an IoT BASE CatM so my conclusions might be incorrect. Firstly M5Core2 for AWS (orange) is the same as M5Core2 (white) - well, except for the color. The secure element (ATECC608) is in the M5GO Bottom2 for AWS (dark gray). From the specs: The M5GO Bottom2 for AWS adds additional features and security for IoT applications. ... the onboard Microchip ATECC608 Trust&GO crypto-authentication chip is pre-provisioned with secure keys to simplify connectivity to AWS and accelerate cryptographic computation. ... In other words to physically stack the IoT Base CatM to the M5Core2 for AWS you have to un-stack the M5GO Bottom2 for AWS first and by doing so you don't have the secure element anymore which I believe is required to connect to AWS. So if you plan to use the SIM7080G to connect to AWS (instead of WiFi) I think the story ends here as you can only have either the SIM7080G or the secure element stacked to the M5Core2 at one time. If your question however is whether a plain M5Core2 (orange or white) can be used with the IoT Base CatM, then the answer is yes. The only thing you need to observe is that between M5Stack (Fire, Base, Gray) and M5Core2 some GPIOs have been changed - so the Arduino example (which is written for M5Stack) needs to be adapted for M5Core2. This list can help you with that. Thanks Felix

  Hi @ajb2k3 - Thanks for the reply. I gather it will take awhile before the M5 gets its hardware updated - the current NRND status is rather "fresh", from 10/2021.
