This is a PCB for all beginners, like myself, who want to quickly build the nodes described in the MySensors website! It can be used with both regulated power and batteries.
This is the RFM69(HW/W) edition of EasyPCB! If you want the original EasyPCB with Nrf24l01+ transiever - go here.
So pretty much this PCB covers all the basic stuff documented in the MySensors website! This cuts my work with one node from a couple of hours (soldering wires) to 20min.
Only easy to solder components with good space in between. Only basic functions (Pro Mini, Radio, Input for sensors and if battery powered booster and voltage divider) Some inputs for all the normal sensors used in the build section. 5x5 or 3x5 depending on function and dynamic in what power you use (Battery, 3.3v or >3.3v (requires voltage regulator).

3x5cm (cut PCB)
Only the lower capacitor marked 0.1uF affects the RFM69 module! The capacitor marked 10uF only affects the input of the voltage regulator.

BAT: Short this if you are using batteries as power supply. It will activate booster circuit and power everything with a stable 3.3v. Make sure you have a corresponding DC/DC step up booster to match your batteries to 3.3v
REG: Use this if you are using 3.3v regulated DC.
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.
Rev 9 - RFM69 Edition
20/7-2017 This PCB is still under development and testings! Its far from finished and comfirmed working
Order 10pcs: 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! Current = Rev 9)
Download from this page to get Eagles and Gerber files.
If you want a faster shipping time or less pieces you can I will soon be selling these from Ebay.
