The T-Bot is a version that incorporates an expansion board on which an HC-SR04 ultrasonic proximity sensor is placed. The T-Block is then installed on a base equipped with a motor to transform the T-Bot into a mini robot! Up to 3 analog sensors can be installed on the expansion board in addition to the HC-SR04.

K210 AIOT with 2MP OV2640 camera

The K210 uses a SoC K210 AIOT of Kendryte instead of ESP32. The easiest way to use the camera module is to use the LiLyGo MaixPy project fork. MaixPy uses MicroPython for programming.

It is also possible to develop in C++ using the library available for the Arduino IDE.

Warning, Kendryte, the manufacturer of SoC K210 seems to have gone bankrupt, or has been bought ?.
