The following sections will help you to help you identify your +Rev. Known issues are listed in the :ref:`errata <errata>`. + +Rev 1 +^^^^^ + +A small number of Maple Rev 1 boards went on sale in late 2009. They +have a light red silkscreen and a single pixelated leaf as a logo. + +.. figure:: /_static/img/maple_rev1.png + :align: center + :alt: Maple Rev 1 + +.. rubric:: Footnotes + +.. [#frev2_4] Revs 2 and 4 were prototypes that didn't pass internal + testing. + +Rev 3 +^^^^^ + +This batch of boards went on sale beginning in May 2010. They have a +darker red silkscreen and the "infinity leaf" logo. The Maple Rev 3 +was the first version which includes the built-in button, labeled BUT. +It also includes a built-in LiPo battery charger. + +.. figure:: /_static/img/maple_rev3.png + :align: center + :alt: Maple Rev 3 + +Rev 5 +^^^^^ + +These boards went on sale in November 2010. They have white buttons, +and "r5" in small print near the "LeafLabs Maple" text next to the +"infinity leaf" logo. The Maple Rev 5 repositioned the double header +on the right hand side to better fit 0.1 inch pitch breadboard. This +necessitated the removal of pins 21 and 22 from the double header; +they are still available, but don't have any headers installed on +them. + +.. figure:: /_static/img/maple_rev5.png + :align: center + :alt: Maple Rev 5 + +Powering the Maple +------------------ + +The Maple's power source is determined by the header to the left of +the "LeafLabs" label on the silkscreen. All versions of the Maple can +be powered from the barrel jack connector, USB, or a LiPo battery. We +ship the Maple with a jumper on the USB selector. In order to power +it off of an alternative source, unplug the Maple, then move the +jumper to the desired selector before reconnecting power. + +You can also power the Maple via the pin labeled "Vin" on the lower +header. However, don't do this while simultaneously powering the +Maple from another source, or you could damage the board. + +Using the Built-in Battery Charger +---------------------------------- + +Maples Rev 3 and Rev 5 also have a built-in LiPo battery charger. In +order to use it, put a jumper across the CHRG header on the power +selection header and across the USB, or EXT selectors, depending on +whether you're charging the battery via USB cable or barrel jack +connector. The LED labeled CHRG will light up while the battery is +being charged. When the battery is finished charging, the LED labeled +DONE will also light up. + +Hardware Design Files +--------------------- + +The hardware schematics and board layout files are available in the +`Maple github repository <https://github.com/leaflabs/maple>`_. The +design files for Rev 1, Rev 3, and Rev 5 are respectively in the +``maple-r1``, ``maple-r3``, and ``maple-r5`` subdirectories. A +schematic for a JTAG adapter suitable for use with Maple is available +in the ``jtagadapter`` directory. + +From the github repository main page, you can download the entire +repository by clicking the "Download" button. If you are familiar +with `git <http://git-scm.com/>`_, you can also clone the repository +at the command line with :: + + $ git clone git://github.com/leaflabs/maple.git + |
