AtomS3U USB otg.

Krist — Fri, 02 Jan 2026 15:34:21 GMT

I tried the following code: import os, sys, io import M5 from M5 import * from unit import KeyUnit from usb.device.keyboard import Keyboard from usb.device.hid import KeyCode keyboard = None key_0 = None def key_0_wasClicked_event(state): global keyboard, key_0 keyboard.set_keys(KeyCode.A, 0, 0, 0, 0, 0) def setup(): global keyboard, key_0 M5.begin() keyboard = Keyboard() key_0 = KeyUnit((1, 2)) key_0.setCallback(type=key_0.CB_TYPE.WAS_CLICKED, cb=key_0_wasClicked_event) def loop(): global keyboard, key_0 M5.update() key_0.tick(None) if __name__ == '__main__': try: setup() while True: loop() except (Exception, KeyboardInterrupt) as e: try: from utility import print_error_msg print_error_msg(e) except ImportError: print("please update to latest firmware") And I got the following error: Traceback (most recent call last): File "main.py", line 5, in ImportError: no module named 'usb' So the usb module is not present in the firmware. Is that on purpose, or is this a bug? Is there a way to add the library?

Atom S3 with UIFlow

Then probably the fact that Atom S3 currently supports only tiny subset of UIFlow features should be made clearer in the product description. I bought an Atom Matrix for a DIY watering project, was fairly impressed with the device (and the whole M5Stack concept) and decided that small local display for current humidity etc would be even better. So I bought the new AtomS3 (described as supporting UIFlow development platform) and currently can't connect it neither to my Watering sensors nor the MQTT data collection server. I will switch my development back to the Matrix and will be looking forward to switch it again when the features I need will be supported in UIFlow 2
