Hello,

I will develop a full featured PCB fitting in a DIN rail enclosure and release it as OSH (Open Source Harware).

I had like to have your feedback obout your needs or interest. The idea is to be able to develop and test the library arduino-zigbee (or with IDF and VS code).

Working with EVK does not help me.

For the moment I will tailor to my future needs:

16 input buttons
20 output relays (230V AC command to lights)
1-wire bus
AC ATM90E26 or 32 1/3 phase power/egy monitor
i2c bus with RTC, I/O expander GPIO, ADC for pH and Chlorine
Water & gas meter with pulse counting
OLED LCD (debug and usage info)
Input buttons and leds for debuggin
USB-C (debug / UART)
230VAC and 5-24V DC input (+output for usage)
Onboard RGB WD2812 for tests
Onboard wrapping aread in order for anybody to test whatever is required
All free GPIO of ESP32-C6
Using ESP32-C-Zero for easy soldering
Onboard ESP32-C6 QFN with external UFL or correct antenna (no ceramic antenna poor range!)
Can add other ESP with WiFi (ESP32-S3) for those requiring more PSRAM.
I can integrate if I get enough polling request what most user want.

I can produce boards and sell at real cost - no margin nothing.

My objective is to help me and others going forward.

Of course the idea (Jan already answered he could be interested) is open to suggestions.

I believe a number of 0-10v analog output to control hydronic radiant in-floor/in-wall/in-ceiling systems, 0-10v thermal actuators, HVAC dampers, fancoil fan speed would really help, HVAC zoning systems and radiant systems are widespread and becoming increasingly common. Likewise RS232/485 serial port for modbus RTU / serial communication would be really useful. Another nice to have might be that the board would be able to interface with DALI 2 bus (I know there is a Pico-DALI2 commercial adapter board based on ESP32) and/or KNX (there is a commercial ESP32-KNX board). Physical ethernet port and maybe POE would also be great. I know I am dreaming. In any case congratulation for your project.

Mhh your are mixing zigbee and esp32 classic. Ethernet the is only with esp32-d0 as others don’t have mac onboard anymore (S3 for example). Rs232 is nogo rs485 is foreseen. O-10 or 4/20mA is ok. Dali will have a look not used too much anymore. Knx is nogo proprietary shit... why not LON 🙂 Can add can bus.
