Look for the Wallbox and Hypervolt EV chargers - they use a Pi inside! :palm: :palm: :palm: :palm: :palm: --- End quote --- Just piss-poor engineering to use something with about 100x the processing power that's needed for the job - an ESP23 would do just fine. And if it wasn't enough of a toy - the Hypervolt also has a bunch of WS2812 LEDs inside to make pretty colour patterns :palm: --- End quote --- Oh dear... I cannot wait the time when they have to RMA them by the thousands when the SD card will start failing. And the WS2812 is also a sure way to get the board yields down the drain, those things are way too easy to damage during soldering. It sounds like those typical devices that are top-down designed by 30 year old "CTOs" who wrote some scripts for embedded systems, so they are immediately experts in the field. --- Quote from: bd139 on September 05, 2021, 09:47:07 am ---It's probably a fair assertion to use a Linux SoC for the network side of it. What worries me is how much control that has over power delivery. I'd hope they hell that was a separate MCU with a constrained verified protocol between it and the host computer. Also the RPi compute module is a dumb idea. Just solder a COTS SoC onto the damn board. There are enough of them out there! --- End quote --- Nah, those boards are less dumb than you think. For example, I had to write Kernel patches for some NXP imx processor because it was powered by 5V, and the internal DC-DC was hardcoded software configured to 3.8-4.2 V. Buying DDR memory, and configuring it is not straightforward. And those BGA packages are difficult to production test. Amongst more things, I would much rather prefer someone else to deal with these issues. |

Indeed. Modules are a design&test (=$$$) saver, especially when DDR is involved. If RF is there... Then Intentional irradiator certification costs can be reduced quite swiftly with a module. |

He had it coming when he started doing Linux for a living and critically relying on corporate contributors, from the US of all places :scared: It's like dealing with Satan - you get superpowers but you sell your soul :P |

Linus was right. Honestly to maintain control of a non trivial software project you have to be an asshole to people here and there. They are nests of complacency and disorder at the best of times all of which cost you dearly later down the line. However you need to nurture good behaviour at the same time. Everyone only talks about how mean people were to them because it’s cheap and easy being a victim. |
