This is a PCB that only contains the basic functions for MySensors but is somewhat dynamic. The main goal was to eliminate the build time soldering wires between the Arduino Pro Mini and the Radio. Its a PCB for all newbies that wants to do basic nodes like myself out there... :)
So pretty much is this PCB for all newbies that only wants the basic part of MySensors documented in the website! This cuts my work with one node from a couple of hours soldering wires to 20-30min
Only easy to solder components (bigger components with legs) Only basic functions (Pro Mini, Radio, Input for sensors and if battery powered booster and voltage divider) Dynamic in what power you use (Battery, 5v or Raw pin). Some inputs for all the normal sensors used in the build section. 5x5 or 3x5 depending on function
3x5cm (cut PCB)
(If you are using regulated 3.3v, use 5v instructions but skip the voltage regulator and bypass this with a jumper between Vin and Vout)
3x5cm (cut PCB)
BAT: Short this if you are using batteries as power supply. It will activate booster circuit and feed the radio directly from the batteries and not voltage regulator
REG: Use this if you are using 5v regulated DC. It will power the radio from the voltage converter.
RAW: This is a MysX feauture. This cuts onboard Vraw source if daughterboard provides Vraw. This is only used when EasyPCB is connected to a daugheterboard.
IRQ (Radio): Pin 2 on the arduino is disabled so you can use this for interupts instead of the radio. Most of the time this pin isnt used by the radio, so therefore disabled. If you want to enable this pin you can connect this jumper.
Rev 9: 13/12-2016 (Not tested)
Order: openhardware.io (Recommended!) and support me and MySensors! (It may say another rev. at the orderpage but this is not EasyPCB rev but the rev for manufacturer. I always update the gerber files for sale)
Rev 8: 23/1-2016 (Tested!)
1) Order DirtyPCB (Not the latestversion, some small changes is made compared to 1).
2) Download from this page to get Eagles and Gerber files. Note that the gerber files are run with Itead cam job.
All free to use as open hardware but I like if you tell me any cool project you make with it :)
All feedback welcome! The main goal is to keep it as simple as possible though.
