A: NO. I was not promoting Raspberry Pi here, merely mentioning the release of board schematics (a Good Thing, IMO). 2012-04-21 17:13 Not sure I understand the latent hostimity to a $35 computer that will run Linux. While not perfectly open, they have released datasheet on the SoC and now we see schematics. As best I can tell, they are not forcing people to purchase the board. 2012-04-21 17:14 Why not let 1,000 flowers bloom? Raspberry Pi may well fail, if so, then it failed. It is not a threat to Ben Nanonote, rather it has very different target market. 2012-04-21 17:16 Ben NN has been an interesting (ongoing experiment). I am not sure Raspberry Pi can not achive a similar level of open-ness as Ben NN. Both have published SoC datasheets. 2012-04-21 17:18 The life forces of qi hardware have already shifted to Milkymist, which has promise, although it will never be a $35 system. Will Milkylist someday be converted to an ASIC? It could happen. 2012-04-21 17:19 s/hostimity/hostility/ 2012-04-21 18:05 what damn latent hostility? 2012-04-21 18:11 wpwrak: (precharge) hah, well you want some proper current limiters in a number of places 2012-04-21 18:21 wpwrak: and I don't think you could place "the capacitor to the right side of switch" here 2012-04-21 18:21 anyway we had sth similar with Vsys on GTA02, no? ;-D 2012-04-21 18:27 (current limiter) a LDO with /ENA input is probably the better alternative to a switch with current limiter 2012-04-21 18:27 this way you got a decent decoupling from system VDD by design 2012-04-21 18:28 and a LDO probably is even cheaper than a switch with current limiter 2012-04-21 18:29 of course this requires some power rail providing Uout + Udrop_LDO 2012-04-21 18:31 running a commerical device without any on-board power stabilization is ... a bit unusual.
