This project is missing a bill of materials. In particular, the LCD components don't appear to be named, not even on the schematic.

Also, do there exist gerber files to accompany it?

Looks like a typical text LCD like 1602 on the picture.

@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)

@marceltrapman when you change the BAUD rate setting in the source/config file to something lower/other you can also use 3.3V Arduinos as (Serial)Gateway. Of cause your controller needs also to be told about the lower BAUD rate. Check out http://wormfood.net/avrbaudcalc.php?postbitrate=9600&postclock=8 for an overview of Clockspeeds (usually 8MHz for 3.3V and 16MHz for 5V types) and coresponding BAUD rates.

@terxw okey, thanks for reporting back !! Let me know if there is something else. This is a 0.5v so I'm open for improvements.

Everything is possible I just added CAD files. If anyone wants to change something.

Hi, for everyone who reads all of this, forget about the last few posts. I don't know why it works even when the Interrups are masked out on the radio, but it works now. The error I had occured because of the config of the OrangePi-Gateway. I removed: --extra-cxxflags="-DMY_RF24_DATARATE=\(RF24_250KBPS\) -DMY_RF24_BASE_RADIO_ID=\(0x00,0xFC,0xE1,0xA8,0xA8\) -DMY_DEBUG_VERBOSE_RF24" and wrote: --extra-cxxflags="-DMY_RF24_DATARATE=\(RF24_250KBPS\) -DMY_DEBUG_VERBOSE_RF24" Now I think I have an working OrangePi-Gateway without signing but with interrupt enabled. If there are new problems I will come back here. The next step for me is to activate signing again and bring the node into homeassistant.

@AWI @Hoffan @sundberg84 I can see both sketches are working, this is what the gateway prints out: 0;0;3;0;14;Gateway startup complete. 0;0;3;0;9;read: 105-105-0 s=255,c=0,t=18,pt=0,l=5:1.5.1 105;255;0;0;18;1.5.1 0;0;3;0;9;read: 105-105-0 s=255,c=3,t=6,pt=1,l=1:0 105;255;3;0;6;0 0;0;3;0;9;read: 105-105-0 s=255,c=3,t=11,pt=0,l=5:Relay 105;255;3;0;11;Relay 0;0;3;0;9;read: 105-105-0 s=255,c=3,t=12,pt=0,l=3:1.0 105;255;3;0;12;1.0 0;0;3;0;9;read: 105-105-0 s=1,c=0,t=3,pt=0,l=0: 105;1;0;0;3; 0;0;3;0;9;read: 105-105-0 s=2,c=0,t=3,pt=0,l=0: 105;2;0;0;3; 0;0;3;0;9;read: 105-105-0 s=3,c=0,t=3,pt=0,l=0: 105;3;0;0;3; 0;0;3;0;9;read: 105-105-0 s=4,c=0,t=3,pt=0,l=0: 105;4;0;0;3; Is this correct?
