Working prototype:

A LEGO set:

That looks really good. Did you made an estimate of the average cost of single node?

[axillent]

@gohan Price is very depends on volume. 10 pcbs are costing me $10 for the set while 50pcs costing $15
Etc. 4pcb for the unit is $1.2-4
Box +$1.3
The rest is BOM, also very depends on volumes and on a unit specific details.

I'm an automation engineer. I build control panels and I program PLCs.
I must say that your project is really interresting.
I always liked the idea of creating DIN rail modules with MCUs, IO...

Keep the good work!

A new design, just ordered PCB. An upgrade of previous MCU PCB:

• STM8S105C6
• EEPROM I2C 512K - to support OTA
  added:

• ADC1115
• DS3231
• ESP-M1
• NCP1529 for 3.3V
• supercapacitor to support RTC
• SH1.0 connector to flash ESP
• 2 pin on base 1
• 2pin on base 2

with soldered ESP will became a local net router, can connect local wired network to Internet and MQTT
also will run RTC application on local and global net

assembled for particular applications

[gohan]

it looks really good

[axillent]

@gohan thanks. working hard to make it good)

[axillent]

this is going to be WiFi router from local 3 wire net to Internet or remote ioT net

[axillent]

wifi router got a firmware and box

can be cloned as many as needed, one per simple network segment
it is managing automated routing between segments

A really impressive project based with DIN interface.
Do you also integrate in DIN format the system to put a mysensors controller as well such as a RPi , etc... ?
