I2C Universal MosFET 2A fused AC/DC OptoCoupler board for ESP32 / Arduino
16 channels, Toshiba PHOTORELAY 100V no clicking, no signal bounce. Switch signals on/off, 2 Amps DC or AC using I2C bus. IO extender PCF9535 Allows many devices on single bus ( > 100 channels). Uses new tech TLP241B, Toshiba Mosfet Opto insulators. Open source project. Updated design 15 Mai 2022. Now LED's are precisely placed on grid. Updated part numbers, added 3d models. Other optimizations have been done. Latest version v2.
Switch signals, DC or AC with an I2C bus, optically insulated with new advanced OptoCouplers.
It can switch relay, a light bulb, or some analog signal, just like with a electromechanical relay.
I will add example code for python/micropython later that shows how to control the I2C bus and the outputs.

Everything is nicely placed on a precise grid.
Feedback welcome.
I will add a little example of using the PCA9535 IO extender soon.
Hope you like it.

We can have 7 cards on a single I2C bus and the tests have been done on 3.3V using an ESP32 dev kit.

I'm writing to express some concerns I have regarding the usability of this forum. I've found it difficult to locate specific files, such as those in the "CAD" and "Schematics" tabs, especially because they're only accessible when logged in. This arrangement isn't very user-friendly and makes finding necessary resources more challenging than it should be.
Additionally, I've noticed there's no efficient way to track updates or messages related to my projects. As it stands, I have to manually log into each of my projects and scan for "unread" messages. This is quite inefficient and has led me to miss important communications. In one instance, it took me a year to find a message simply because I don't routinely log into all my projects.
I suggest implementing a notification system for messages associated with users' projects. This would greatly enhance the user experience and ensure important updates are not overlooked.
I hope these concerns can be addressed in future updates to improve the platform's usability.

The files are there Schematics+ CAD TABS, please take a look and, if you do please notify me, I want to know how long it takes before you see my message on this page.
