Re: MatchboxARM
I'm tired of the anti-3.3V logic arguments. What does commodity even mean? Does it mean standard? What does standard even mean in MOSFETs? It's not like there are any standards... there may be...

Just an FYI, even if you wanted to change the multiplier, the driver can be speed pulsed, to the next several steps, and will settle and the new step as long as it is less than a whole step. This...

what would be nice is if board manufacturers would either include 5v shift level voltage buffers to i/o or the hardware that attaches can output 3.3v logic signals, which by the way is detectable and...

Hello. I want to tell you some more things the MatchboxARM. The micro used is STM32F103C8T6, it has 72MHz, 64Kb Flash, 20Kb RAM, also on the same board can be used the STM32F103CBT6 128Kb Flash! The...

Fascinating thread, especially since MatchboxARM folks have joined us Just want to repeat earlier question, is there a benefit of using micro faster than 16/20 MHz when controlling a RepRap?

View ArticleRe: MatchboxARM
On the subject of cost, a complete RAMPS kit goes for about €116 on ebay, Smoothieboard when it was on sale was about €110 and that includes 120Mhz ARM with 512KB Flash and Ethernet. So I would say...

Have you considered using one resonator intead of a crystal and two caps? The Murata-Electronics CSTLS20M0X53-B0 is ideally suited for this, lowers the parts count as well as the cost.

Thank you! so now im trying to decide between an E3D to j-head :P, can i hear some opinions or recommendations from some E3D or j-head owners?
View ArticleRe: Sanguish development
Yes, although the crystal is about the same price at the supplier I use and the caps are pennies. Also the crystal is tighter tolerance. Not sure if that makes any difference with our type of use. I...
