So what can this be \ud83d\ude09 ?<\/p>\n<p>Looks like this is the new CPU board which will be used in UP! box or Mini2 to support wireless. Based on the footprint and layout we can assume this:<\/p>\n<p>ANT : Antenna<\/p>\n<p>U3: ESP8266 (ultra cheap WiFi CPU)<\/p>\n<p>U2: MX25&#8230; (serial flash required by ESP8266, content unknown yet since IC is missing)<\/p>\n<p>RX \/ TX: Led showing serial communication between UP! main CPU(U1) and ESP8266<\/p>\n<p>LINK \/ SYS: Led showing state of wireless connection of ESP8266<\/p>\n<p>&nbsp;<\/p>\n<p>So how can we upgrade our old printer to be compatible to UP! Studio without even opening it?<\/p>\n<p>Here comes the plan:<\/p>\n<ul>\n<li>take a cheap $10 WiFi router with USB host like the TP-Link TL-WR703N (still available for cheap from some Chinese sources)<\/li>\n<li>change the firmware to OpenWRT<\/li>\n<li>write a small package for OpenWRT which emulates the ESP8266 functions from UP! wireless (looks like some simple UDP and TCP is used to tunnel the standard USB traffic to the printer)<\/li>\n<li>bridge the received data\u00a0between WiFi and USB<\/li>\n<li>optionally we can add a small USB Hub and a cheap USB WebCam and whatever else you might have in mind<\/li>\n<\/ul>\n<p>\ud83d\ude42<\/p>\n<p>UPDATE:<\/p>\n<p>I played a bit and it turns out UP!Studio sends an UDP broadcast to the subnet (sending it&#8217;s own IP address and ports) and expects an UDP response. It also opens a TCP server socket and waits for the printer to connect to it. Most likely the data communication is handled via this connections later.<\/p>\n<p>UPDATE 2:<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-large wp-image-4389\" src=\"http:\/\/stohn.de\/3d\/wp-content\/uploads\/2016\/03\/upstudiowifi-1024x609.png\" alt=\"upstudiowifi\" width=\"1024\" height=\"609\" srcset=\"https:\/\/www.stohn.de\/3d\/wp-content\/uploads\/2016\/03\/upstudiowifi-1024x609.png 1024w, https:\/\/www.stohn.de\/3d\/wp-content\/uploads\/2016\/03\/upstudiowifi-300x178.png 300w, https:\/\/www.stohn.de\/3d\/wp-content\/uploads\/2016\/03\/upstudiowifi-768x456.png 768w, https:\/\/www.stohn.de\/3d\/wp-content\/uploads\/2016\/03\/upstudiowifi-1024x609-200x118.png 200w, https:\/\/www.stohn.de\/3d\/wp-content\/uploads\/2016\/03\/upstudiowifi.png 1176w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/p>\n<p>Getting closer \ud83d\ude42<\/p>\n<p>UPDATE 3:<\/p>\n<p>IT&#8217;S WORKING \ud83d\ude42 \ud83d\ude42 \ud83d\ude42<\/p>\n<p>UP Studio WiFi printing with my UP mini (only hardware required: a $10 TL-WR703N)<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-large wp-image-4391\" src=\"http:\/\/stohn.de\/3d\/wp-content\/uploads\/2016\/03\/UpStudioWifiWorking-1024x700.png\" alt=\"UpStudioWifiWorking\" width=\"1024\" height=\"700\" srcset=\"https:\/\/www.stohn.de\/3d\/wp-content\/uploads\/2016\/03\/UpStudioWifiWorking-1024x700.png 1024w, https:\/\/www.stohn.de\/3d\/wp-content\/uploads\/2016\/03\/UpStudioWifiWorking-300x205.png 300w, https:\/\/www.stohn.de\/3d\/wp-content\/uploads\/2016\/03\/UpStudioWifiWorking-768x525.png 768w, https:\/\/www.stohn.de\/3d\/wp-content\/uploads\/2016\/03\/UpStudioWifiWorking.png 1333w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/p>\n<p>The project needs some cleanup before publishing.
