<![CDATA[M5Atom Matrix and micropython]]>The Problem

I just flashed a vanilla micropython for esp32 on the M5Atom matrix. There seems to be an issue with network. I can connect to it, enter REPL and play with micropython. However if I try to turn the RF part on, the chip reboots. The reason being a power-on reboot.

An example is:

import network # Ok
wlan = network.wlan(network.STA_IF) # Ok
wlan.active(True) # Reboot on the matrix

I also have an M5Atom Lite and I have no problem using either the WiFi or the Bluetooth modules with micropython

The question

Is my M5Atom Matrix faulty, or is there a problem with micropython?

Basically it reboots because of a brown-out due to a power consumption that is at the limit of what a plain usb port can deliver.
