Connect to MicroHydra (MicroPython) on M5Stack Cardputer

Connect to the Cardputer running MicroHydra using UART REPL via serial

1. Plug in and find the serial port

ls /dev/cu.*

Typical outputs:

/dev/cu.usbserial-1410
/dev/cu.usbmodem2101

That’s the device you’ll connect to.

2. Connect with a serial terminal

You can use several tools:

Option A: screen

screen /dev/cu.usbserial-1410 115200

Exit with: Ctrl+A then K then y.

Option B: mpremote (recommended)

Install:

pip install mpremote
brew install mpremote

Connect:

mpremote connect /dev/cu.usbserial-1410

or just:

mpremote

(it will auto-detect if only one device is connected).

# List files on the device
mpremote ls

# Copy file from Mac to ESP32
mpremote cp myscript.py :

# Copy file from ESP32 to Mac
mpremote cp :main.py .

# Run a script directly on device
mpremote run myscript.py

Option C: minicom / picocom

brew install minicom
minicom -D /dev/cu.usbserial-1410 -b 115200
