1. Introduction
This is a multi-functional expansion board designed for control boards, equipped with XH2.54 power ports (DCIN: 7-12V), supporting 7-12V wide voltage input to power the expansion board and control board; equipped with a power switch and signal indicator light, intuitively controlling the circuit on and off and displaying the power supply status.2.54mm header connector: compatible with universal Dupont wire.
2, Characteristics
1. Provides multiple composite interfaces, supporting the simultaneous expansion of multiple devices
2, on-board power switch, can conveniently control the power supply of the expansion board
3, on-board 2.54mm pitch G|V|S expansion pin interface, more convenient for connecting sensors
4, on-board motor signal toggle switch, flexible to meet motor control requirements
5, XH2.54 power port, convenient for connecting lithium battery power supply
3, Expansion Board Parsing
IO port P0, P1, P2, P8, P13, P14, P15, P16 is a PH2.0 3P socket
These ports are terminated with 3P PH2.0 sockets, convenient for beginners to connect wires.
P1,P0,V,G bracket/P16,P15,V,G bracket/P19,P20,V,G/P9,P8,V,G bracket
This socket circuit is designed for VCC/38/39/GND to facilitate mating with some modules using a PH2.0 4P interface. (Adaptable module: HS-S63-LTCS342 color sensor, HS-F14LTM1650 four-digit LED digital tube module, HS-F15LTM637 four-digit clock digital tube module, HS-F19LOLED display, HS-F21LLCD1602 display, )
P0,P1,P2,V,G seat/P9,P14,P13,V,G seat
This sub-circuit is designed as 12/10/11/V/G for easy connection with some matching modules using PH2.0 5P interfaces. (For example, HS-F13L)8x8 dot matrix display moduleHS-F24-L1-digit digital tube)
D,P13,P14,G seat/D,P15,P16,G seat
This sub-circuit design can only be connected to LEGO motors, and the manual control can be achieved by toggling the switch on the right bottom of the development board,P13,P14,P15,P16The motor is not connected.Pay attention to P13, P14, P15, and P16 being used for other purposes requires that the switch be turned to off!!
