Hello, This module is finally available to buy assembled. Now our project is complete, you can run the whole RS485 system after some shopping here, on openhardware.io. See details on the project pages. Cheers, feanor-anglin

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 @animal64, we are glad to welcome you in the MySensors community. I don't use MQTT, but one of users, who took the gateway, did some work in this direction, you can find on this link - https://gitlab.com/denissp/mdmsgate_mqtt/ Yes, for each type of radio module you need your own gateway, its own subnet. This means that two gateways are needed. If you have any questions, please contact us, we will always be happy to help
