DIN Rail LEGO
A LEGO set:
That looks really good. Did you made an estimate of the average cost of single node?
@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
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:
- EEPROM I2C 512K - to support OTA
- 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
it looks really good
@gohan thanks. working hard to make it good)
this is going to be WiFi router from local 3 wire net to Internet or remote ioT net
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
