Quiz Answer- smallest unit in KiCAD

printed-circuit-board-design-124847_800x345

Smallest unit in KiCAD is 1 nm. This is (1/1 000 000)-th of millimeter.

Quite precise for PCB design!

For comparison the popular Eagle CAD base unit is 1 um which is 1000 times bigger, so KiCAD uses 1000 times more precise metrics than Eagle.

Actually lot of the modern chips today are made on 28-40 nm technology.

So maybe KiCAD designers when deciding to use 1 nm as smallest unit were thinking too expand KiCAD as ASIC mask generation tool in future?

…who knows:)

KiCAD knowledge base – Quiz Answer: KiCAD can have up to 32 copper layers

kicad

KiCAD can have up to 32 copper layers, quite plenty to finish even very demanding PCBs + 14 technical layers like masks, silk prints, components adhesives, solder paste, edge milling etc. + 4 auxilary layers for drawings and comments.

Thanks for all who participated the quiz. Random.org says our winner is @PetrMoses . Congratulations! Waiting to email us at info@olimex.com your address to send your prize.

 

Friday Free Board Quiz prize is A20-OLinuXino-LIME, Question: How many copper layers you can have in PCB design with KiCAD?

a20-olinuxino-lime-1

A20-OLinuXino-LIME is Open Source Hardware low cost Linux single board computer with native Ethernet, LiPo battery charger, native SATA and HDMI.

What makes different this board from other similar is that ALL board peripherals keep running from single LiPo battery in case of power loss. i.e. if you have SATA drive connected and USB dongles plug they will keep operating until battery discharge.

Recently we made upgrade to A20-OLinuXino-LIME2 which have Gigabit Ethernet and 1GB RAM and added industrial temperature -40+85C eMMC Flash 4GB which can operate in both MLC and SLC modeto A20-OLinuXino-LIME2-eMMC . Now we are one step away to offer completely industrial grade LIME2 as we successfully tested KSZ9031 Gigabit Ethernet PHY interface from Microchip which performs up to 700MB up and down link and Microchip is offering it in industrial grade too, so it’s matter of time to have completely industrial version of LIME2 operating -40+85C.

 

You can win A20-OLinuXino-LIME!

Appnotes and Tutorials about Debugging UEFI and Linux Kernel on Intel SoCs with OpenOCD and ARM-USB-OCD-H or ARM-USB-TINY-H

INTEL-OPENOCD

Intel made nice video tutorial how to use OpenOCD and our JTAGs with their SoCs! This explains the frequent purchases they do from many Intel locations all around the world of ARM-USB-TINY-H , ARM-USB-OCD-H and ARM-JTAG-20-10.

Searching bit more there is application note How to setup ARM-USB-OCD-H with Intel Quark SoC X1000 and tutorials about Low-cost UEFI debugging options for Intel and How to debug Linux Kernel on Intel Quark

MOD-RFID1356MIFARE NFC / RFID reader writer for MIFARE 13.56Mhz tags

MOD-RFID1356MIFARE

MOD-RFID1356MIFARE is re-design of our popular RFID card readers. It’s based on NXP PN532 chip and can read and write in ISO/IEC 14443A/MIFARE tags.

Like with MOD-RFID125 and MOD-RFID1356 it’s extremly easy to use. It connects via USB to any computer and creates HID keyboard or CDC serial port. There is no need for any drivers and switching between the modes is very easy with one push button.

WiKi description explains how to use. Read distance is up to 15 cm for ISO cards. We will stock soon 4 different types of tags: ISO card, clamshell, keychain and adhesive sticker.

A20-CAN – new OSHW board designed with KiCAD adds CAN networking to A20-OLinuXino and A20-SOM

A20-CAN

Want to sniff your car’s CAN bus or to drive Industrial machines with CAN networking bus?

Allwinner A20 SOCs have CAN but almost no one use it. If I remember correctly it was not even included in the Allwinner documentation just two pins had CAN on their names, so many people doubt if there is or not CAN.

Fortunately some people investigated further and add proper CAN support for A20 Linux, so we decided to make small driver board which to allow A20-OLinuXino and A20-SOM to have CAN. What does this means? Now you can use A20-OLinuXino to talk to other devices with CAN like industrial equipment, automotive CAN bus etc etc.

Current Linux image we have is without CAN support, but we put instructions on our WiKi how to build one with Linux-Sunxi 3.4 Kernel and with Mainline kernel: https://www.olimex.com/wiki/A20-CAN

What you see above on the picture is our first prototype of A20-CAN it works well although we use 5V CAN driver and A20 is 3.3V device. We successfully connected AM3352-SOM-EVB to A20-OLinuXino-LIME with A20-CAN driver and exchanged some messages at the highest speed 1Mbit and it works fine.

All CAD files, Gerbers, BOM are in this Github account: https://github.com/OLIMEX/A20-CAN . The board is done with KiCAD.

The PCBs are now in production and in 2 weeks A20-CAN will be orderable on our web page . While the PCBs are made we will work to add the CAN in our official images, so you do not have to bother with Kernels configurations and re-compiling.
