HI, I’m new to this and have just signed up for the ESP32 course, which looks very comprehensive.
I have ordered the recommended board from Ebay but I have noticed that there are many boards on offer, that have the same description apart from some letters on the end of the description, such as
ESP32 ESP32S CP2102 Development Board 2.4GHz Dual-Mode WiFi+Bluetooth Antenna YJ
ESP32 ESP32S CP2102 Development Board 2.4GHz Dual-Mode WiFi+Bluetooth Antenna ON
Can someone please explain the difference?
All ESP32 development boards come with a PCB antenna.
To be honest, I have no idea what those letters at the end mean. I think those letters vary depending on the seller (but I’m not sure).
We usually get our ESP32 boards from Banggood, or from eBay (seller alice1101983).
If anyone knows what those letters mean, please let us know.
