README
README.mdAaram
PCB design for retro fitting old switch boards with new tech to control it remotely using ESP32-C6-Mini-N1.
Features
- Controls 4 loads using
- 1 Triac
Note: Triac circuit has added protection for the back EMF generated by inductive load like fan.
- 3 Relays for controlling other resistive loads
Try not use heavy inductive load using relays. During testing, the MCU was bugging out when load was switched.
- Input from switches.
- To reduce rewiring the whole switch board, directly connect the rocker switch output terminal to the input provided on the board.
- The FULL BRIDGE RECTIFIER rectifies the AC which is sent to the quad channel opto with a 100k resistor in series for current limiting. The output from the opto is read by the ESP.
- Fuse holder in series with the AC input for overload protection.
- Varistor on all AC output terminals for protection from transient spikes.
- Added support for IR receiver and transmitter.
- Uses DHT22 for temperature and humidity sensor.

Questions
How big is the Aaram PCB?
It measures 100 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Aaram use?
77 parts, built around the ESP32-C6-MINI-1U-H4, BT136-600E, AZ1117D-3.3TRE1 and BC817-25. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Aaram KiCad files?
From the xicor22/Aaram repository on GitHub, at the commit this page was made from: the board is Aaram.kicad_pcb and its schematic Aaram.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Aaram design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
