After a quick search, i see many having problems with the power brick mini which comes with pixhawk 2.1
Basically, it has no documentation and i cannot see a specific option in power modules list in MP. Setting “Other” and 17 as volt x A scale, gives no current information. If i connect my Pix with usb, it gives a measurement in the 0.6 a area, but useless (?).
my battery is connected to Power1 and i tried different configurations, also the one i found here:
BATT_MONITOR = 4
BATT2_MONITOR = 4
BATT_VOLT_PIN = 2
BATT2_VOLT_PIN = 13
BATT_CURR_PIN = 3
