Is it engineering validation v1.3 silicon or proper v3.x production silicon as per all latest chips?

Hey there, @Sam294483, and welcome to the forum. Glad to have you here.

It looks like the chat disconnected before you got your response yesterday.

The ESP32-P4 on the [FireBeetle 2 ESP32-P4 AI Vision Board (360MHz RISC-V, MIPI CSI/DSI, Wi-Fi 6) (SKU: DFR1172)  
 ](http://core-electronics.com.au/dfrobot-firebeetle-2-esp32-p4-riscv-ai-vision-iot-development-board-wifi6-mipi.html) are labelled as P4NRW32. This marks them as the older v1.3 version and not the 3x range, which would have been denoted by P4NRW32x.
