How to reduce your PCB assembly cost & production risk by optimising schematic and BOM. Dave explains three ways to consolidate your project PCB Bill Of Materials (BOM), to make your products potentially cheaper and easier to manufacture with less supply risk. As well as being an essential good design practice! A look at a complex FPGA based design with a large number of components, how far can this design be optimised and for what benefit? https://github.com/ciaa/Hardware/tree/master/PCB/ACC/CIAA_ACC Forum: https://www.eevblog.com/forum/blog/eevblog-1307-tutorial-pcb-bom-consolidation/ #PCB #Design #Tutorial EEVblog Main Web Site: http://www.eevblog.com The 2nd EEVblog Channel: http://www.youtube.com/EEVblog2 Support the EEVblog through Patreon! http://www.patreon.com/eevblog AliExpress Affiliate: http://s.click.aliexpress.com/e/c2LRpe8g Buy anything through that link and Dave gets a commission at no cost to you.

Dave takes a look at the Orange Pi One $10 single board 4 ARM Cortex A7 processor computer and compares it to the Raspberry Pi 2. Coving the install of the ARMbian flavour of Debian. Beware the security bug! And what is the power/watt efficiency between the two? http://www.orangepi.org/orangepione/ Schematic: http://linux-sunxi.org/images/7/7e/ORANGE_PI-ONE-V1_1.pdf Allwinner H3 datasheet: http://linux-sunxi.org/File:Allwinner_H3_Datasheet_V1.2.pdf Open source Allwinner H3 community: http://linux-sunxi.org/Main_Page ... https://www.youtube.com/watch?v=TEyU1zSqFwU
