1. No wiring: We integrate wiring in circuit board, so no worry about the wrong wiring to burn the module.
2. Multiple functions: With ESP32 development board as control board, this box contains 16 sensors and modules, and it is available to either external 7-12V DC power or 6 AA batteries.
3. Simple structure: Ready-to-use and full shell package prevents hands from being scratched by pins and protects the board as well.
4. Strong expansibility: Four RJ11 interfaces are reserved beyond the shell, all of which are compatible with IIC communication.
5. Basic programming learning: Graphical programming for new hands to cultivate programming logic and foundation; MicroPython programming for developers to contact the underlying codes combined with hardware.
