Please post pictures!

I bought radxda board before however the support for it is very limited. The best could be a som with a good support and a competitive price but today we dont have this option. I think for now the best available option is Pine64 with 2gb ram. I propose to make a github and build a common board with our collaborative work. I can do something in hardware side but it is way too much for one person, and I am not really expert on it. I would like to touch on the issues discussed before: 1) Power The best option should be pow management via an simple arduino controller even an attiny 85 would work. When there is a bus activity (remote key unlock) the pine64 will start to boot up and when the ignition removed pine64 will start to shutdown. I can help with the schematics. 2) Sound We dont need to amplify the output the amplifier can be external and can stay in the car forever. The sound output should be differential 5ch output with derived from 2ch by an audio mixer IC. If we have digital output, it can be helpful for some car owners which have onboard dsp. 3) Linbus/canbus Can be achieved by very cheap ICs can be found. 4) Screen LVDS or RGB screens should work with pine64 and they are relatively cheap. The maximum lenght for lvds cable is 20cm but we can use logic level converters to amplify it to 5V or 12V and we can use longer cables. 5) Camera Analog input can be used it with usb adapters but also we can use raw camera input with using logic converters as we can do in screen part. 6) USB If we need powered USB it should be piped to extension board we make and externally powered. 7) Buttons They can be easily implemented through GPIO. RE: Pine64 Head Unit - Traveler - 10-05-2016 I would love to see Canbus. I have a couple of waterproof /fuse/relay boxes mounted under the hood. Each box can handle 10 relays but would settle for 8 for simple bit reasons. The wiring between the switches is a huge time and material consumer. I would love to be able to read the switches at 12 volt levels then translate that to Canbus on a slave then send to a slave mounted inside the relay box. Another feature would be to have 12 volt inputs on the Relay box slave so that it can monitor the fused output of the relays. On the switch panel, each switch has two LEDs one LED is a panel lamp to identify the switch, the other LED is to indicate an on condition. By monitoring the fused outputs on the relay box side and sending that status back to switch panel slave to illuminate the 2nd LED to indicate good condition. Switch on and no 2nd LED would be blown fuse indication. Reason for staying with 12 Volt rather than TTL is because I can use common off the shelf automotive parts and it allows it to be configured with direct wiring instead of Canbus if someone wishes to. There are commercial products that are available to do exactly this but are high priced for the DIY crowd. A future option could be a touch screen on the Master to provide a GUI switch/indication screen eliminating the need for mechanical switches and mounting. I have found some I2C boards I could do this with, but I think the environment is too noisy electrically to cover the distance between inputs and outputs. RE: Pine64 Head Unit - mbt28 - 10-06-2016 Hi, Actually I couldnt get what do you mean exactly? What is this 12V line? Is it a bidirectional 12V level serial line? If it is, it is quite easy to implement is with couple of diodes or small ICs. RE: Pine64 Head Unit - Zoidiano0 - 10-09-2016 Hey guys good news mi new LCD has just arrive I install it on my playbox enclosure and burn the. Android 7 image Due the gpio are available now from default in the kernel we might be able to use them I have download some libraries to start working on some apps to use them If u have some info of how to make them work any help is welcome @mbt28 Thanks for the suggestions going to post them in the fist post to keep it clean to new users Thanks to all to keep this thread alive Please any progress on your ideas please post them Thanks [GRINNING FACE WITH SMILING EYES] Sent from my Xperia V using Tapatalk RE: Pine64 Head Unit - Traveler - 10-09-2016 (10-06-2016, 02:50 AM)mbt28 Wrote: Hi, Wow had to figure out why the quote function didn't work like other forums. No it is not a bi-directional serial line. It is a logic line that is at a 12 volt level but due to being an automotive application you have to becareful of voltage spikes well above 20 volts. I have located some I2C boards with either N Channel Mosfet outputs to drive the existing 12 volt relays. Also found some I2C shield with opto-isolated inputs rated 3-30 volts that I can use to wire the existing switches to. Here are the Output boards I found. https://www.ereshop.com/shop/index.php?main_page=product_info&cPath=143_182&products_id=806&zenid=c9fe48f1ed71d6b21518e6729df3a46c These are the input boards. https://www.ereshop.com/shop/index.php?main_page=index&cPath=143_181&zenid=c9fe48f1ed71d6b21518e6729df3a46c I have to do some dimension checking to make sure the output boards will fit into the waterproof relay box and the input boards will fit in behind the mounted switches.
