Freenove ESP32-WROVER simulator, the camera board
The Freenove ESP32-WROVER (FNK0060) is a classic ESP32, of which one Xtensa LX6 core runs here, on forty pins named by GPIO with USB-C and a BOOT button. Its blue LED is on GPIO 2, and WiFi joins a simulated network. The OV2640 camera is drawn but not simulated.

What is modeled
Taken from the board's own contract document and put in plain words, with what is missing beside it.
Modeled
- Core
- One Xtensa LX6 core, the DevKit V1 model whole
- GPIO
- Every pin on the headers, numbered as the silkscreen numbers it; 34 to 39 are inputs only
- ADC1
- VP, VN and 32 to 35
- The blue LED
- GPIO 2, lit when the pin is HIGH, as LED_BUILTIN
- UART0
- TX and RX, wired to the serial monitor
- WiFi, simulated
- WiFi.h over a network written in software: no radio, no 802.11, and real internet only when you sign in and switch it on
Not modeled
- The OV2640 camera: its pins are ordinary GPIOs here and no image comes from it.
- The 8 MB of PSRAM, and GPIO 16 and 17, which it uses and the board does not bring out.
- The second core, ADC2, the DAC and touch sensing.

Questions
Is it free?
Yes. Every board and every part is on the free plan, with no account needed.
Does the camera work?
No. The camera is drawn, but nothing simulates it, so esp_camera and its image never arrive. Everything else on the board does run.
Is it the same as the ESP32 DevKit V1?
Same chip and same firmware, other board: forty pins named by GPIO, USB-C, and the camera socket, where the DevKit V1 has thirty pins.
Why are 16 and 17 missing?
The WROVER module uses them for its PSRAM, so the board does not bring them out.
