The 328 buddy is a bread boarding tool for the ATMega328 dip package.
This board still need to be completely veted, so purchase the current version at your own risk. So far everything seems good.
This board acts as a backpack and sits right over top.
32Kb additional I2C eeprom storage
required 4.7k pullups
selector switch for selecting ISCP mode or debugWire mode
serial breakout ala sparkfun ftdi friend thing.
schematics and what not are below. The board is alone is also available through PCBs.io link on the left hand side. As well as my Tindie store for those of you who don't want to put one together or are a little squeamish when it comes to smd components.
As a note, the selector switch footprint is a little small... I will fix that and update the PCBs.io link to the new board files.
The 328 buddy is a bread boarded tool, allowing you to quickly breadboard a 328. Just snap the backpack over the 328 and your done.
Has an extra 32Kb EEPROM, and the required 4.7k pull ups on board, 16Mhz crystal, a reset switch, blink led, power led ICSP/Debug port and serial breakout.
I designed this a long time ago but never got around to actually building it. I'll release the schematic's etc soon.
Can also be found on my pcbs.io page, as well as my Tindie store. Feel free to build them yourself. They are on my Tindie store if you don't want to spend the time building one and don't mind throwing me a few bones :)
