Hardware description This small USB powered board accepts commands from an infra-red remote to control the behaviour of a strip of RGB LEDs. I started to document this as it seemed like a great low power interface for all sorts of things as it contained a microcontroller, serial eprom, 3 driver transistors, an infra-red receiver and connections for 3 switches. But once I found the datasheets for the mic… text/html 2023-04-05T13:29:10+12:00 electronic:led:coh309toa http://www.projects.scorchingbay.nz/dokuwiki/electronic/led/coh309toa?rev=1680658150&do=diff [COH309TOA overview] LED Description ModelCOH309TOA/E1Manufacturer Recovered fromClockBoard IDsCOH309TOA/E1, PC-1 94HBDigits3½ColourredDriver IC Arduino driver Connectorpin headerNum Pins16Pin spacing0.1” [segment labels] Pin#digitsegdigitseg1 am21bpm31c2e42b2g52c2d62a2f73f3a83g3b93d3c103e4e114b4g124c4d134a4f14 : 15 k2 16k1 text/html 2023-10-23T20:06:22+12:00 electronic:led:sidebar http://www.projects.scorchingbay.nz/dokuwiki/electronic/led/sidebar?rev=1698044782&do=diff LED module data * COH309TOA/E1 * BJ-0324 text/html 2019-11-16T10:11:56+12:00 electronic:led:start http://www.projects.scorchingbay.nz/dokuwiki/electronic/led/start?rev=1573852316&do=diff [Cone icon by Fornax, CC-BY-SA 3.0, wikimedia commons] I have a few LED (light emitting diode display) modules, recovered from various scrapped devices, that I wish to use in Arduino projects. They vary from 1/2” high single digit displays to tiny multi digit calculator displays.
