I cannot say if that is the problem. I can say you should never use a regulator without a bypass cap on it.

Does your LM7805 regulator have 0.1uf bypass caps on both the input and output ?

I think that it's more likely that the issue is that your devboard already has an USB-to-serial-converter connected to the Tx and Rx pins, and that connection is interfering. Suggest you use the onboard USB port to program the board instead.

Dam, something so obvious... Good call ESP_Sprite!

If you want to automatically flash you will need 2 more connections. EN & GPIO0. Your USB to serial board does not support it. There is a sequence with these 2 pins to put it into flashing mode. You can manually put it into flashing mode, but you will have to press and hold down the boot button, the...

This place has the 16MB, but not with 8MBram, just 4MB.

A ESP32 module with onboard Ethernet PHY chip. Without the 9 RMII lines internally connected there will be 10+ lines left only to be routed outside to make the end-users' RJ45 application much easier! Na, that will increase the cost for all who dont even use Ethernet. Adding a PHY chip is ultra sim...

I was looking into the new ESP32-S2, primary because it says this: With LCD interface and 14 configurable capacitive touch GPIOs, ESP32-S2 provides the optimal HMI solution for touchscreen and touchpad-based devices. From this Link: https://www.espressif.com/en/products/socs/esp32-s2 I was looking a...

In short, I can't express how frustrated I am with Arduino, and how great ESP-IDF has been. Simular issues here. I started out with Arduino only because I was new to espressif. As time moved on and I started moving on from simple hello world, toggling GPIO and so on to adding peripherals and making...

Try sticking a delay(10); or delay(100); in your loop().

What voltage is sensors output ?
If it's 5v you have a problem. You need to get it to 3.3v.
