Where to get the Sanguino Chip ? In one of my experiments I must have gotten some EMF into my Sanguino Chip as some of my PWM pins stopped working. I have the Sanguino breakout board so I was going to populate that also. But I seemed to be unable to source the ATMEGA644P-20PU-ND chip? https://reprap.org/forum/read.php?13,22087,22087#msg-22087 Sat, 18 Jul 2026 22:43:30 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?13,22087,22130#msg-22130 Re: Where to get the Sanguino Chip ? https://reprap.org/forum/read.php?13,22087,22130#msg-22130
If you want this chip with a bootloader pre-installed, you might look at the RBFK644 from [wulfden.org] it comes with a few other components (and probably costs more than the unprogrammed avr), but it's apparently in stock. I have no experience with this Co., yet -- but they did answer my question re stock status very promptly. I may order another sanguino or shield from them, since they have it in stock (and rrrf.org's store seems to be out, still.)

In that case... Use one with less flash?]]> Annirak Controllers Wed, 11 Mar 2009 17:22:54 -0400 https://reprap.org/forum/read.php?13,22087,22120#msg-22120 Re: Where to get the Sanguino Chip ? https://reprap.org/forum/read.php?13,22087,22120#msg-22120
Here's a migration document.

Digikey has almost 1700 of these in stock and zero of the P model.]]> freds Controllers Wed, 11 Mar 2009 15:50:05 -0400 https://reprap.org/forum/read.php?13,22087,22112#msg-22112 Re: Where to get the Sanguino Chip ? https://reprap.org/forum/read.php?13,22087,22112#msg-22112
Normally, I'd suggest digikey, but they seem to be out of stock at the moment. I'd suggest just getting the ATMEGA644-20PU instead. It just takes a little more power than the ATMEGA644O-20PU.]]> Annirak Controllers Wed, 11 Mar 2009 12:23:18 -0400 https://reprap.org/forum/read.php?13,22087,22087#msg-22087 Where to get the Sanguino Chip ? https://reprap.org/forum/read.php?13,22087,22087#msg-22087
