Power? - baz123 - 10-21-2016 This may seem a stupid question, but does the device need to be powered? If so is there a minimum power required? What is the power consumption? RE: Power? - admin - 10-21-2016 yeah, it is powered via standard Micro USB cable. The devices with the CDM 7160 sensor consume ~15 ma, with short peaks up to 300 The ones with the CM1102 consume ~150ma, and peaks up to 300 in general there are problems with power supplies (i have at least one 1$ chinese one) that cannot supply even 300 ma at 5v. Also there are some power supplies that deliver more than 5.25 v (as per usb spec) and with those - the CDM 7160 sensor has problems RE: Power? - baz123 - 10-21-2016 Great thanks. |
