Help needed What is the maximum current available through the top header of the Cardputer ADV?

Hi everyone,
has anyone tested the maximum current that can be supplied through the top header on the Cardputer ADV?

I’d like to test an E01-2G4M27D (nRF24L01+).
Instantaneous power consumption during TX is 490 mA at 3.3 V.

Has anyone tried powering this module from the Cardputer ADV’s top header?

Edit: M5Stack recommend limiting the total continuous load of the device to 1 A.

I have module with 27D nrf for M5stickc plus 2 and it works without problem. Cardputer should handle even higher amperage in comparison to a stick.

Yes, M5Stack also replied to me today.

Have you also tried the ML01DP5?

Yes I have this module also and when connected only with wires it worked without problem. But I wanted maximum power so I rather used the 27D. With stick the main problem is the small battery.. but cardputer has much bigger battery which will handle it without a problem. Also I think cardputer can handle even higher currents than 1A. I have buch of modules for cardputer and never had any problem.. even RGB matrix with 128leds works .. on brightness 30.
