I missed the 4-layer mention in the documents. I was not planning to install KiCAD to find out part footprints :-)</p> <p>So it might be a bit of a stretch to do it using 1206/0805 and 2 layers, unless I made the PCB bigger. </p> http://forums.leaflabs.com/topic.php?id=74127#post-104936 Sat, 16 Nov 2013 17:16:52 +0000 bnewbold 104936@http://forums.leaflabs.com/ <p>gbulmer: I believe it mostly used 0402 components; some were 0805. The documentation says it's a 4-layer board.</p> <p><a href="http://leaflabs.com/docs/hardware/maple-native-beta.html" rel="nofollow">http://leaflabs.com/docs/hardware/maple-native-beta.html</a><br /> <a href="https://github.com/leaflabs/maplenative" rel="nofollow">https://github.com/leaflabs/maplenative</a> </p> http://forums.leaflabs.com/topic.php?id=74127#post-104935 Sat, 16 Nov 2013 16:44:42 +0000 gbulmer 104935@http://forums.leaflabs.com/ <p>I'm curious. Was the Maple Native a 4-layer PCB? Ignoring the STM32 and memory, what size components did it use? Was it all 0402, or something a bit more DIY-able? </p> http://forums.leaflabs.com/topic.php?id=74127#post-104898 Wed, 13 Nov 2013 13:42:51 +0000 gbulmer 104898@http://forums.leaflabs.com/ <p>randomvibe - You might consider an <a href="http://www.st.com/web/en/catalog/tools/FM116/SC959/SS1532/PF252419">STM32F4DISCOVERY</a></p> <p>It has an STM32F407VGT6 microcontroller with, 1 MB Flash, 192 KB RAM but only an LQFP100 package.</p> <p>However, it is only, about, $16:<br /> <a href="http://www.futureelectronics.com/en/technologies/development-tools/microcontroller-microprocessor/32-bit-eval-board/Pages/6011574-STM32F4DISCOVERY.aspx?IM=0" rel="nofollow">http://www.futureelectronics.com/en/technologies/development-tools/microcontroller-microprocessor/32-bit-eval-board/Pages/6011574-STM32F4DISCOVERY.aspx?IM=0</a><br /> <a href="http://www2.mouser.com/ProductDetail/STMicroelectronics/STM32F4DISCOVERY/?qs=sGAEpiMZZMutVogd4PRSvEN8XDBeCtgD" rel="nofollow">http://www2.mouser.com/ProductDetail/STMicroelectronics/STM32F4DISCOVERY/?qs=sGAEpiMZZMutVogd4PRSvEN8XDBeCtgD</a><br /> <a href="http://www.digikey.com/product-search/en?x=0&amp;y=0&amp;lang=en&amp;site=us&amp;KeyWords=STM32F4DISCOVERY" rel="nofollow">http://www.digikey.com/product-search/en?x=0&amp;y=0&amp;lang=en&amp;site=us&amp;KeyWords=STM32F4DISCOVERY</a><br /> or £10:<br /> <a href="http://uk.rs-online.com/web/p/processor-microcontroller-development-kits/7458434/" rel="nofollow">http://uk.rs-online.com/web/p/processor-microcontroller-development-kits/7458434/</a><br /> <a href="http://uk.farnell.com/jsp/search/productdetail.jsp?sku=2009276" rel="nofollow">http://uk.farnell.com/jsp/search/productdetail.jsp?sku=2009276</a></p> <p>You might also have a look at the STM32F429IDiscovery:</p> <p>It has 8MiB RAM, and a touch LCD, which uses up a lot of its pins<br /> e.g. <a href="http://www.st.com/web/catalog/tools/FM116/SC959/SS1532/LN1199/PF259090?s_searchtype=partnumber" rel="nofollow">http://www.st.com/web/catalog/tools/FM116/SC959/SS1532/LN1199/PF259090?s_searchtype=partnumber</a><br /> It's about £16 in the UK<br /> <a href="http://uk.farnell.com/stmicroelectronics/stm32f429i-disco/stm32f4-discovery-eval-board/dp/2355377?Ntt=2355377" rel="nofollow">http://uk.farnell.com/stmicroelectronics/stm32f429i-disco/stm32f4-discovery-eval-board/dp/2355377?Ntt=2355377</a><br /> <a href="http://uk.rs-online.com/web/p/processor-microcontroller-development-kits/7892815/" rel="nofollow">http://uk.rs-online.com/web/p/processor-microcontroller-development-kits/7892815/</a></p> <p>(Full disclosure: I am not a member of LeafLabs staff, nor any of those companies linked to) </p> http://forums.leaflabs.com/topic.php?id=74127#post-104896 Wed, 13 Nov 2013 13:01:22 +0000 bnewbold 104896@http://forums.leaflabs.com/ <p>It won't be a product we sell, sorry the page is out of date.</p> <p>We did spin one prototype and I think it worked fine, we simply ran out of steam for testing, documenting, and productizing it (which ends up being the majority of the work). </p> <p>The design files (Altium, not kicad or eagle) are on github: <a href="https://github.com/leaflabs/Maple-II" rel="nofollow">https://github.com/leaflabs/Maple-II</a></p> <p>I think somebody around here mentioned a blackmagic-style integrated STM32 dev board recently; I think we're recommend that if you are looking for something now. </p> http://forums.leaflabs.com/topic.php?id=74127#post-104895 Wed, 13 Nov 2013 05:12:05 +0000 randomvibe 104895@http://forums.leaflabs.com/ <p>The link leaflabs.com/devices says that the Maple Native Beta is closed, and Maple Native II is being worked. Is this still the case, and if so, when will it be available? The number of I/O pins, ADCs (21 total!), peripherals and chip specs are extraordinary. </p>
