  • How much current will this draw on the 3.3v “LV” pin if I use this module for serial communication? Will it draw more than 5mA?

  • I’ve purchased this awesome device, though I have one small problem with it: I have it basically ‘sniffing’ serial communications going from an Arduino to a radio transmitter (so everything that is sent to the radio is saved onto the SD card). About 50% of the time the OpenLog starts blinking and not writing anything - it goes into ‘emergency mode’, this means that the RX pin was LOW for at least two seconds.

    As you can imagine, this is quite bad. There is a 50% chance that the OpenLog will do absolutely nothing upon boot. I know that I can reflash the Openlog to remove this ‘emergency mode’, but I don’t have the required equipment (an AVR programmer), are there other solutions? Can I just put in weak pullup resistor?

    Thanks
