I/O Expansion Board for R3 DIY Sensor Modules

I/O Expansion Board for R3 DIY Sensor Modules Description

1、When using, just stacks the expansion board on for R3 control board, use a specific wiring to connect the sensor/module. 2、Anti‑reverse interface, fixed wire sequence, and sensor/module will not be burnt out due to the reverse connection of the wire sequence. 3、3 pin interface silkscreen is generally G V S, where all G on expansion board represents GND, V represents the VCC (5V) interface, and S represents digital port/analog port above interface. 4、2 sides of the expansion board also come with a 2.54mm female header interface, and the wiring sequence is the same as that of the for R3 board header interface. 5、At the same time, the expansion board comes with a reset button, a reset button indicator (D2), and a power indicator (D1). 6、In order to fix the expansion board to other equipment conveniently, the expansion board only has two positioning holes with a diameter of 3mm.
