aeric Expert Licensed User Longtime User Feb 19, 2024 #1 Hi, As far as I know the usual way to program an ESP-01(S) is using a USB to TTL/Serial Port Adapter/Programmer either CH340G (I read that it is not very stable) - 2x4 pins female perfect for ESP-01 - I have ordered one but not yet arrived CP2102 or CP2104 (more reliable) - 5 pins male FT232RL - 5 pins male PL2303 (not stable) - 4 pins male Have anyone tried to program ESP-01(S) using Arduino UNO? I found this: https://www.hackster.io/pratikdesai/how-to-program-esp8266-esp-01-module-with-arduino-uno-598166 I am wondering is this working with B4R? Which board should I choose in B4R?

T thetrueman Active Member Feb 20, 2024 #2 Your research is on the right path... All the modules in your pictures will work but just focus on correct connections. ESP01 (third pic) will directly fit on the USB with yellow color header (first picture). Upvote 0

aeric Expert Licensed User Longtime User Feb 21, 2024 #3 Yes, I know but my adapter is not yet reached so I thought I find another way to program the ESP with just jump cables. It is possible but it may need more time to research so I decided just wait for the adapter to arrive and save my time doing more research unless I have free time to do more testings. Upvote 0

This is good link showing detailed pics to wire the UNO and ESP01... Also on your other post, there is video link, that is also good to follow. Upvote 0

T thetrueman Active Member Feb 22, 2024 #6 Yes it can work but be sure to use 3.3V on this USB-Serial Module. Better check voltage with meter before wire to ESP01 module. Upvote 0

I programmed ESP01/ESP-03/ESP12E with no problems. Arduino has a serial converter on board, (ATmega 16u2) It's not a very simple method Upvote 0
