Small-footprint Due
hi guys - need expert feedback on due board designing. we wanted build smallest possible footprint due-compatible board embedding our products (such our open source ev charging stations, ev chargers, etc - info curious ones: http://www.emotorwerks.com/products/online-store/product/show/44-emw-juicebox-level-2-15kw-ev-charging-station-kit-or-assembled-unit). we have sifted through posts find on various relevant topics try collect gotchas (e.g., errors in schematics, suboptimal i2c pullup resistor values). have looked various types of user feedback design board can not useful interesting others making small production runs based on sam3x8e. e.g. have added 64kbit eeprom on board, broken out aref pin, etc. at moment, able 4-layer layout containing lqfp-144 package fit 1.2"x1.4" footprint. have external programming board due programming circuit on it. way small production runs way more economical don't have spend $$ , board space on programmer circuits don't us...
