So I have an ESP32 Thing: https://www.sparkfun.com/products/13907
Bidirectional LLC: https://www.sparkfun.com/products/12009
and a 4 channel 5v Relay board: http://www.ebay.com/itm/5V-Four-4-Chann … 2048264659
I am trying to use the ESP32 to control the relay board. Here is my mockup:

I have a 5v 5A power supply on the top breadboard rail, and using the ESP32’s 3.3v on the bottom rail. in this configuration, the ESP32 will not boot. if i change it to use 3.3v → VCC on the board, and removed the JD-VCC jumper, and apply 5v directly to JD-VCC. Then go straight from the esp32 to in1 and in2, it will work for only one about 80% of the time. the LED turns on and off, but the relay wont flip. sometimes it will.
My main question, is what is wrong with the schematic above?
