I am trying to get the reference (C6, S3 ....) of the chip I am using since it is embedded in a module. Is it possible to have this information? The best I got from espflash board-info is:

Chip type:         esp32 (revision v3.0)
Crystal frequency: 40MHz
Flash size:        4MB
Features:          WiFi, BT, Dual Core, 240MHz, Coding Scheme None

Yours is an ESP32, no suffix. It's in the first line. I guess the lineup is a bit confusing but if it's a different variant, board info will say so.

e.g. for me:

❯ cargo espflash board-info
[2023-10-17T09:06:13Z INFO ] Serial port: 'COM4'
[2023-10-17T09:06:13Z INFO ] Connecting...
[2023-10-17T09:06:13Z INFO ] Using flash stub
Chip type:         esp32s3 (revision v0.1)
Crystal frequency: 40MHz
Flash size:        8MB
Features:          WiFi, BLE
MAC address:       68:b6:b3:2d:94:7c
