@kimot No, it is an obvious mistake, I am very sorry. Maybe it is becouse the code in master branch is very old, the newest is not yet on github, but the developement branch is quite new. I am going to fix this soon.

Is this design for some existing enclosure?

@sineverba I see Thanks for clarifying.

@shabba The majority of the components are 0603 SMD package type (except 2 smd resistors on the usb lines which are not really mandatory and can be replaced with a solder bridge). There you go (extracted from schematic - I can't do better than this because it involves more work and I don't have time for it, sorry): a) 9 x 100nF 0603 SMD MLCC capacitors, X5R/X7R (voltage can be 10V and above) b) 3 x 1uF 0603 SMD MLCC capacitors, X5R/X7R (voltage can be 10V and above) c) 1 x 10uF 0603 SMD MLCC capacitor, X5R/X7R (voltage can be 10V and above) d) 1 x 22uF 0603 SMD MLCC capacitor, X5R/X7R (voltage can be 10V and above) e) 1 x 10nF 0603 SMD MLCC capacitor, X5R/X7R (voltage can be 10V and above) f) 1 x ferrite bead 0603 SMD blm18he152sn1d g) 3 x 330 ohm 0603 SMD resistor h) 1 x 1Kohm 0603 SMD resistor i) 1 x 10Kohm 0603 SMD resistor j) 1 x 56Kohm 0603 SMD resistor k) 1 x MCP1703A-3302 3.3V/0.25A voltage regulator l) 1 x TXB0104 voltage level converter m) 1 x ATMEGA328P-MU AVR MCU (QFN32 package) n) 1 x CP2102 USB to serial (QFN28 package) o) 3 x 0603 SMD LEDs (your pick here) p) 1 x ATSHA204A (SOT-23 package) q) 1 x RFM69W module (your pick regarding working frequency) r) 1 x ZTTCS16.00MX ceramic resonator s) 1 x USB A type male connector for PCB and 1 SMD reset switch (I have no exact links for this, sorry)

Hi @berkseo. Thanks for the suggestion, but could you describe in more detail? As for my TODO list, there is already a task to add 485 interface to the gateway. My latest device "xRoom" have this interface. ps/ Where have you gone? I have been working on "xRoom" shield. A small announce: Do you remember the discussion about multinode? So, it will be available soon))
