So I have an M2 that per the online docs states that if I power the M2 via the JST, then I can use the micro usb as host power for another device. I cut into a micro usb, connected the red and black wires to the second device and it did nothing. My understanding is that it would host 5v but it did not. Am I doing something wrong?
Hi Seth,
May I ask you to elaborate on which power source you use? Does it provide 5V 3A power?
I’m using a dc down converter that pulls from a 22v DC battery.
Hi Seth,
Does the Reach M2 power on with your setup?
May I also ask you to specify the DC/DC converter you are using?
Yes it does power on. Here is the converter I am using.

Hi Seth,
Sorry it took so long to get back to you! We’ve been trying to reproduce your setup to find out what might be the cause of your issue.
May I ask you to clarify whether you connect a host device over USB-OTG cable? It’s the only way to make them work together.
Also, could you post your hardware setup photos?
Yes that is correct. I took a micro USB cable and cut one end of it to use just the positive and negative ends to try and power the second piece of equipment.
