How to power Reach M2¶
Emlid Reach M2 module can be powered using Micro-USB port or JST-GH ports. Power circuit is shared for all ports, so when you power the device over one port it will pass power to other ports.
Make sure that you have a stable power source for Reach M2. We recommend using USB 3.0 or 5V source with up to 3A. Only the red LED lights up when M2 lacks power.
Do not plug two power supplies at the same time as it may damage the device.
Power supply over USB¶
You can power Reach over Micro-USB cable using power supplies like:
- Power bank
- USB wall adapter
- Computer USB ports
Powering using JST-GH ports¶
Reach can be powered by providing 5 Volts to corresponding pins on any of the two JST-GH ports.
When Reach is powered over JST-GH port it will pass power to devices connected to Micro-USB OTG port such as flash drives, 3G\4G modems, USB radios etc.
