#MikesElectricStuff explains that Shenzhen Fine Mad (or Fine Made) Electronics (FM) has a “74HC595A” that can’t run nearly as fast as a normal 74HC595, lacks the enable pin, and has open-drain outputs. Unfortunately lots of anti-Chinese racism & xenophobia in the comments from “bd139”, “jonpaul”, “SL4P”, “floobydust”, and a particularly repugnant specimen from “CaptDon”. #electronics #hardware
on 02026-09-03#MikesElectricStuff recommends some fast-turnaround #PCBA companies in the #UK: <https://hcd-electronics.co.uk/> which he used to use and <https://www.fringeelectronics.co.uk/> (not fast), plus <https://www.ablcircuits.co.uk> (which he hasn't tried) and <https://www.pcbtrain.co.uk/> (“nearest thing UK has to JLC, but at much higher prices”). Also a discussion thread about how to qualify suppliers and reduce BOM delays. #electronics #hardware #manufacturing
