Talk:Vaporware Electronics
February 2015 and the Raspberry Pi Foundation has just released a quad-core ARM Cortex-A7 version of the Raspberry Pi for the same low price of $35. It runs Debian Linux armhf (32-bit) quite properly.
I personally believe that using a combination of a Raspberry Pi quad-core running Linux and a more than proven AVR Mega for realtime tasks together would provide any RepRap with more than enough processing power and connectivity options required for the foreseeable future - all that at an unbeatable price.

- Yes. And it's almost trivial to replace such an ATmega with some 32-bit CPU, as Gen7-ARM and 3DPCB show. Then not even polar or delta printers should experience a processing power bottleneck. --Traumflug (talk) 04:53, 3 February 2015 (PST)
- Hi Markus, I was not aware of the existence of the Gen7-ARM, it seems like a really interesting controller board. I hope it is further developed and can be offered as an economical 32-bit alternative to what we have right now. But, a single ARM M0 core @ 50MHz is rather far from a quad core ARM Cortex-A7 @ 900MHz in terms of processing power. So I am still of the opinion that combining a multicore ARM SOC on a mass-produced board with an AVR 8-bit MCU-based Arduino (also mass-produced) offers - in February 2015 - the best combination of processing power, cost and feasibility. Of course things can (and do) change very quickly, let' s see what the coming months bring us in terms of developments in this area. --AndrewBCN (talk) 06:14, 4 February 2015 (PST)
