Why Robomaster TT is more expensive than Tello EDU?

The reason for this question is that Robomaster tt add a extension kit. Robomaster tt expension kit includes open source controller, ranging dot-matrix screen extension module and adapter extension board. Below is the specs of robomaster tt expansion kit.

Open source controller

Weight：12.5 g (including the open source controller and ranging dot-matrix screen)

Operating mode：AP and Station modes

Wi-Fi frequency band：2.4 GHz and 5.8 GHz

Bluetooth：2.4 GHz

MCU：ESP32-D2WD, dual-core at 160 MHz, 400 MIPS

Open source：Supports SDK development, Arduino, graphical programming, and MicroPython programming.

Scalability：14-pin extended interface (for I2C, UART, SPI, GPIO, PWM, and power supply)

Programmable LED indicator：Full-color LED

Ranging dot-matrix screen extension module

Dimensions：35.3×31.5×8.6 mm

Programmable dot-matrix LED indicator：8×8 red-and-blue indicator

Dot matrix driving function：IIC interface, automatic dot matrix scanning, 256-level adjustable overall brightness, and 256-level adjustable single-LED brightness

Ranging module：Infrared distance sensor (ToF)

Adapter extension board

DIY adaptation

14-pin extended interface to the 2×7-pin 2.54-mm in-line pad, 2 power indicator positions, and 2 debugging indicator positions

So robomaster tello talent is more expensive than tello edu, and it worth it.

If I already have a tello edu, and you want to upgrade to robomaster tt, what you need to do is buy a ROBOMASTER TT expansion kit.
