I have a 5V FTDI board so will need a logic level converter
So to upload a program to the ESP-01:
Just assembled perfboard, need to test it
So push the button on the board and "If a blue light will switch on momentarily on the ESP module, then your ESP is in programming mode."
Board doesn't seem to be working. Checked at the vcc/ground pins of the ESP8266 model and seeing 0V, even though I checked for connectivity and it was fine. Maybe the logic level shifter board cannot supply the ESP8266 model with adequate voltage? Will test this whole setup again on the breadboard and see if it worked. Can't remember if it worked
on the breadboard I connected the ESP-01 module to a 3.3V power source and the red power light came on, so I am assuming the logic level shifter is not sufficient enough to power the board, idek why i thought that was a good idea lol
Using these logic level shifters: https://www.amazon.com/gp/product/B07LG646VS/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
They are showing 3.3V on the out supply side Checking the board right now without the ESP-01 connected to see if there is a connection issue. not seeing 3.3V at the header pins where the ESP-01 would go
Might be some errors in the board
Think on my perfboard I must've flipped the LV and GND pin connections between the logic level shifter and the ESP-01 headers. Need to un-solder it and redo it
