ESP32CAM is an image recognition development board. It features an ESP32 (4M Flash + 520K RAM) chip and 2-Megapixel camera (OV2640). It also supports image transmission via Wi-Fi and debugging through USB Type-C port.
The hardware comes with a preloaded software, programmed by ESP-IDF. The purpose of the pre-loaded software is to operate the Wi-Fi camera. The camera output image has a resolution of 600*800, since it's 2MP camera it's possible to optimize the software to output a bigger resolution of photos.
What can the software do?
|Maximum resolution||200w pixel|
|Transmission rate||UXGA/SXGA: 15fps, SVGA: 30fps, CIF: 60fps|
|Output format||YUV(422/420)/YCbCr422, RGB565/555, 8-bit compressed data|
The module comes with a self-contained program. It is a nice program to demonstrate the camera. However, 1) I think the "can" program was developed with ESP-IDF not Arduino. 2) there is no instruction to change the SSID of the module.
A simple sketch for the Arduino environment at the product page would be nice.
It worked well. Picture quality good.
Device works as advertised.
Good products. Took 11 days to Japan via registered China Post mail with tracking. Packet in hard shelled box. Demo works (http://192.168.4.1). The plastic housing (case) interfares with the antenna and the side switch. There needs to modify the plastic case little bit.
