The calibration code, as well as the Remote Client and ESP32 codes, are all there for your hacking pleasure. Its been a while since we have seen OpenCV in action like with the Motion Tracking ...

ESP32 上的 UART 控制器支持多种字符长度和停止位。 另外，控制器还支持软硬件流控和 DMA，可以实现无缝高速的数据传输。 我们这里就是简单的介绍一下 这里再讲LEDC外设，ESP32芯片-LEDC外设（另附Arduino代码），如果觉得这里浅尝辄止，可以看我前几日写的这个文章。

It still needs to be plugged into a board to hold the motor drivers like the Arduino, but beyond that [bdring] opines the ESP32 is about as close to the perfect Grbl platform as you can get.

An undocumented set of low-level commands has been discovered in the ESP32 microchip, a widely used component in IoT devices. Manufactured by the Chinese company Espressif, the ...
