This is a bare-board (PCB) only. You supply the ESP32 and other parts, You build as many of the features as you want.

What is it?

• ESP32 breakout board
• See photo for specific required version of ESP32 board
• TCA9544 - 4-Channel I2C and SMBus Multiplexer With Interrupt Logic
• Isolated I2C channels
• I2C Channels can be independently powered with 3.3V or 5V
• I2C Channels can be powered from the card or use external 3.3V or 5V power
• Interrupt for each I2C channel
• Jumper selectable I2C base address
• FTDI header
• SPI bus header
• GVS (Ground, Voltage, Signal) for all ESP32 pins
• 5V power source selection/distribution
• 5V sources - USB, 5mm terminal block, DC jack
• On-board 3.3V power regulator (doesn't stress the ESP32 regulator)
• 95x95mm ODAS form factor
• 6-32 mounting holes

Why did you make it?

I needed an ESP-32 design along with an I2C hub. I wanted GVS pins for easy power distribution to sensors. I wanted my own source of 3.3V for external sensors.

What makes it special?

It does it all in one board.
