The power source is determined by the header +labeled "PWRSEL" on the silkscreen. Boards are shipped with a jumper +on the USB selector. In order to power it off of an alternative +source, unplug the Maple Native, then move the jumper to the desired +selector before reconnecting power. + +You can also power the Maple Native via the pin labeled "Vin" on the +vertical header to the right of the PWRSEL header. This pin feeds +into both the digital and analog voltage regulators. However, don't +do this while simultaneously powering the board from another source, +or you could damage it. + +We recommend an input voltage no greater than 12 V. + +Using the Built-in Battery Charger +---------------------------------- + +Maple Native includes a built-in LiPo battery charger. In order to +use it, put a jumper across the CHRG selector on the PWRSEL header and +across the USB, or EXT selectors, depending on whether you're charging +the battery via USB cable or Vin, respectively. The LED labeled CHRG +will light up while the battery is being charged. When the battery is +finished charging, the LED labeled DONE will light up. + +.. _maple-native-b-gpios: + +GPIO Information +---------------- + +The Maple Native features 106 total input/output pins, numbered ``D0`` +through ``D105``. In most cases, these numbers correspond to the +numeric values next to each header on the Maple Native's silkscreen. +However, pins ``D101`` through ``D105`` are broken out to the +:ref:`JTAG <jtag>` header, and are not numbered on the silkscreen. In +addition, some other pins have other uses by default [#fusedpins]_. + +.. _maple-native-b-but: + +Pin ``D6`` is the Native's :ref:`button pin <lang-board-values-but>`. +It is thus mainly useful as an :ref:`input <lang-pin-levels>`. The +pin will :ref:`read <lang-digitalread>` ``HIGH`` when the :ref:`button +is pressed <lang-isbuttonpressed>`. + +.. _maple-native-b-led: + +Pin ``D22`` is the Native's :ref:`LED pin <lang-board-values-led>`. +It is thus mainly useful as an :ref:`output <lang-pin-levels>`. The +LED will glow when ``HIGH`` is :ref:`written <lang-digitalwrite>` to +it. + +.. _maple-native-b-fsmc: + +.. FIXME [0.0.12] Add note on Native "use SRAM" vs. "no SRAM" builds +.. +.. TODO [0.0.12] Specify which pins are safe, and which aren't + +Many of the pins on the right header (pins ``D56`` through ``D100``, +the header is labeled "FSMC" on the silkscreen) are connected to +:ref:`FSMC <fsmc>` lines. Using these pins as GPIOs may render the +memory chip useless, which can cause your program to crash. For this +reason, we don't recommend that you use these pins unless you know +what you are doing. + +.. _maple-native-b-jtag: + +Pins ``D101`` through ``D105`` are connected to the pads on the +:ref:`JTAG <jtag>` header. In order to use them as GPIOs, you must +first disable the Maple Native's debug ports. You can do this by +calling :ref:`lang-disabledebugports`. (Note that this means you +won't be able to use JTAG or SW-Debug to debug your program). + +..
