ESP32 - New Test Board

ESP32 – New Test Board, MUCH more than a breadboard

Here I am presenting a very useful test board for the notorius uC ESP32 (AZ Delivery version).

Since it was available on the market, it gained a lot of interest for its performances but the only odd thing is its form factor not very useful to make some test on breadboard or similar.

Features

Starting from this project RPi (Raspberry Pi) – GATE007, a useful test board, I developed this test board dedicated to this microcontroller, so give a look to its performance:

12 digital inputs (drived by negative signal) with LED status and opto-isolated and Schmitt triggered with the ability to invert the signal
8 digital outputs drived by 8ch MosFet ULN2803 with the ability to choose the output voltage between 12Vdc or 5Vdc
I2C bus channel with four ports for 3.3VDC and four port for 5VDC (it can be useful using devices with differents power level and no needs to add level shifter to have all different sensors working together)
6 pin for each voltage level (+3v3, +5, +12, GND) where to connect your sensors quickly
a radio-receiver up to 6 channels for remote control with LED status
main power from main 220vac with LED status on fuse defective
two different Zero Cross Detection circuits for experimental porpouses.
