Yet energia.nu says: "LaunchPad pins can source (provide positive current) or sink (provide negative current) up to 40 mA (milliamps) of current to other devices/circuits."
I note that the Arduino documentation says the same 40mA, so suspect this specification may have accidentally been copied from the AVR. If so, seems like an invitation to release the magic smoke.
Please someone either point me to where the documentation says that the various launchpads can source/sink that much, or fix the web site to either include the actual numbers for the various launchpads, or remove the misleading number.
I previously posted this question on stellarisiti (where it failed to generate any action), but just noticed that the web site says to post documentation corrections on the 43oh Energia forums.
