I would like to power the SP140 using an external power supply. The Hardware User Guide describes various power modes including a battery mode but gives very little information for where to connect an external power supply. I assume that I could possibly use "battery" mode or tap into the Arduino connector but there is no information on how/where to do this. The best scenario is to be able to jumper onto the board somewhere and then be able to turn power on and off using S5.
Any help from someone who has done this would be appreciated.
