PB Pro Mini

By
No, it isn't Lead, nor is it Peanut Butter.  It is the 'B' version of the prolific ATmega328P microcontroller which started all this maker craziness off!

Description

This is a minimal microcontroller board with only a voltage reg, crystal, I2C pull-ups, LEDs and the chip itself.  The goal here is to reduce costs while hosting the beefy 328PB!

This is based on, and pin compatible with, the Arduino Pro Mini 5v/16MHz from Sparkfun.

Notable, not-so-minor improvements for the 'B' version:
  • 2 UARTs
  • 2 I2Cs (TWI)
  • 2 SPI
  • Qtouch
  • 5 Timers (with OC, IC, and PWM)
Everything else is about the same.  You should be aware the clock driver on the chip is a low-power version, but this board and crystal operate at 16MHz just fine at 5V.  The Arduino library I've been using for the PB has been working without a problem!

Getting Started

You'll need a FTDI Friend or FTDI Cable to program this as there is no secondary USB chip, like on the Arduino Uno. You'll also need the Arduino libraries to support this new micro (see my blog post), or go directly to Watterott's GitHub.

Purchase

If you send me $10 and an address via PayPal, I'll send you one (5V, 16MHz).  Of course it'll be hand soldered!  Lower US states only, unless you send me extra for international shipping.

Atmega328PB Dev on Linux x64

By
The Atmega328PB is the greatest thing to come to the Arduino platform since the UNO.  Who wouldn't want more 16-bit PWMs and double all 3 serial protocols? The new unofficial Arduino Mini PB Pro! To get the IDE to support it, follow this guide: https://github.com/watterott/ATmega328PB-Testing Since the JSON file is incomplete for Linux, do the manual toolchain replacement.  This was a little tricky, and there isn't much on the internet on where the toolchain resides inside the Arduino base folder.  Here's what I did to make it work. I downloaded the latest Arduino build, and I will refer to the extracted base directory as "arduino-1.6.9".  Also download the "hardware.zip" and the "Arduino Toolchain (4.9.2)" Linux x64 version from the github links. 1. Replace the toolchain The builtin toolchain resides in "arduino-1.6.9/hardware/tools/avr/".  Rename the avr folder to "avr.old".  Extract the "Arduino Toolc...

Geode LX800 cash-in

I discovered an AMD Geode processor lurking in a slim client SBC (single board computer) originally for a printer kiosk.  I wonder if I could fit a TinyGentoo  onto its 128MB compact flash card??? Introduction and overview I will utilize crossdev, and avoid any chrooting problems and mismatching CHOST/CFLAGS... Customize the target systems make.conf generated by crossdev. Compile and install packages into runtime tree. [picture of slim client and screen] >>>I'm writing this while my Gentoo system cross-compiles a i486-pc-linux-uclibc toolchain into /usr/i486-pc-linux-uclibc. There are many resources that I had to pull together to get this working: http://en.gentoo-wiki.com/wiki/Tiny_Gentoo  HOWTO guide to install a 5MB system on a USB flashdrive or similar http://www.gentoo.org/proj/en/base/embedded/handbook/index.xml?full=1  Gentoo Embedded Handbook details cross-compiling for various dev boards http://judepereira.com/blog/going-...
