This is a 4" LCD (480x480) with a RPi Pico and an ESP3-2S3.

I want to use it in my car as a scangauge "work-alike". OBD-II CAN bus

I had a Garmin EcoRoute for a few years but it no longer works. I miss the gauge displays, especially for engine temperature.

I want to try to calculate MPG.

I would normally expect a product like this to be Android/Debian/Ubuntu but this is lower level, that intrigues me. I want to know the architecture and how to program it.

ESP32 manages wireless (WiFi, BT 5 and LoRa) and the LCD/touch panel. It says it has LoRa and it says "optional" so ? I wonder if I get one or not?

RP2040 has a 32GB SD card and 2 Grove interfaces, one for I2C and one for analog. It has the speaker too.

USB: there are two USB-C ports and an internal USB hub. Both processors are attached to the hub, the ESP32 has a USB->UART interface.
