ESP newbee, which ESP is which

ESPHome

I have two ESPHome devices that were all ‘canned’ projects. Trying to work through this one;

and need to buy (another) ESP board, and confused on the variations

First was a " ESP32-S2FN4R2 ESP32-S2 4MB Flash Type-C Connect" which I can not even get to power up, and was a miss as they do not have BLE

Then I got Development Board Base on ESP8266 ESP-12F for Arduino, which power up, and I can program from ESPHome, but Seems like the project needs specifically ESP32??

So where can I go read about the veriety of board and understand what I need.

  • ESP8266 ESP-12F
  • D1 Mini NodeMCU ESP32 ESP-WROOM-32
  • ESP32 ESP-32D ESP-WROOM-32 CP2012
  • Arduino Nano ESP32 Without headers [ABX00092] ESP32-S3
  • ESP32 Mini D1 Mini NodeMCU ESP32 ESP-WROOM-32

It seems that the word " WROOM" should not wory me as it is just refering to the SoC??

Appreciate someone guiding me boefore I buy another 3 or 4 of the wrong boards for the project.

p.s.

The reason I am at this is the yaml for the project is erroring on the need for ESP32.

Component ble_adv_controller requires component esp32.

and I see that I have

esp8266

Thus, I assume I need another board?

Esp8266 is the old chip.
Its replacement is esp32
Esp32 comes in many versions, but for ESPHome you need the WiFi version, so S2, S3 or C3.
I suggest you got for one of the S variants and maybe S2 as a preferred one, because it is better supported by the many guides you can find.
The support is often just tinkering with the settings and once you get it right then that part is solved for the future.

I always shop at the official Espressif Store.

If you just need a board to tinker with then find a devkit board.

Esp wroom32 is the most supported general purpose dev board and would be my first choice if there is no specific reason to choose S or C variants.

S2 does not have Bluetooth as OP wants.

Thank You - I am seeing ESP32D I assume D is the next version after C? Is that code compatible with C?

No, D is just a version of normal Esp32 board, with PCB antenna.

S2,S3,C2,C3,C6 are completely different chips.
